First things first, thanks for your effort and a truly quality product. Next, I’ve noticed that suddenly MKVCleaver is SLOW to launch….Like 30 to 45 seconds slow. I didn’t seem to take that long when I first installed it. Is there something that could be gumming up the startup that I could possible clean up?
Really thanks for your work!! Its awesome! The only thing is… is slow :o( I’ve Intel Core i7-6950X 25M Broadwell-E 10-Core 3.0GHz (oveclocked to 3.8GHz) LGA 2011-v3 140W processor, 128 DDR4 – 3200, aCOOL sys w/420 rad (stress test: full 3D 60fps, 24h, fans speed 1450 rpm – never plus that 35C) 4 WD VelociRaptor WD1000DHTZ 1TB 10000 RPM 64MB Cache SATA 6.0Gb/s 3.5″. Any idea why 3.8GB took 28 h?
MKVCleaver is a GUI so it doesn’t actually extract anything. Mkvextract.exe is doing all the work. You may need to ask Mosu on doom9 forums.
If I had to guess though, it could be an antivirus or other security software constantly scanning the extracted data as it’s being extracted or a bad HDD. Maybe try extracting the same file when all the security software is turned off or make an exception for the destination folder so its not being scanned. Check your OS partition for errors as I’ve seen NTFS journal errors cause very slow systems.
Thank you for a positive comment. I’m glad you like it.
I would consider making a GUI for muxing in the future, but first, I would like to know what is wrong with the mktoolnix-gui.exe that comes with the MKVTollNix package ? It has batch job mode.
Yeah, yeah, I know that you have to pay for your site…but you really don’t need to be such a dick about it. There *are* other ways to get the money. People use ad blocking software for a reason, and you apparently don’t understand what the reason is. Since you’re such an annoying little prick, I find it worth the bother to comment. Eat shit and die, you fucking little shit. Grow up and get a fucking life, punk. It isn’t like your puny GUI is the most wonderful and necessary program out there, and, if it’s such a big deal to you that people not use your bandwidth for downloading it, there sure as fuck ARE places that will host the fucking thing. If you can’t think any better than this, then your crap is probably not worth my time anyway. However, I will take a look at it, I won’t whitelist your sorry ass, and I’ll STILL download it from your site. I’m not going to tell you how I do it, but you’re not the only greedy little bastard attempting to block people this way…and I’ve found that it isn’t at all difficult to bypass your so-called blocker. Have a nice fucking day, kid.
So much anger, you must be an American redneck I’ve heard so much about. 🙂
So, Mr. Redneck I would like to thank you for your kind comments. Yes, as you already figured out the download block is largely symbolic and yes there are other places where you can download MKVCleaver: VideoHelp or SoftPedia to just name a couple. If you do a Google search you can find hundreds of sites hosting the files.
In the future, please be more respectful in your comments. You are entitled to your opinion (free speech and all), however, I ask that you express it in a less angry manner.
I just started using your GUI and whilst looking for info on it, I came across this discussion.
Wow. That is one angry guy and his logic makes no sense. He expects you to do a load of work without payment and for you to also pay for the bandwidth that allows him to get it for free. How he can call you a “greedy little bastard is beyond me.
It’s a wonder people like this don’t put off more software developers like you. Well done for your only mildly racist, but otherwise extremely restrained reply. Also thanks for the GUI.
I’m assuming you reloaded the page after disabling the AdBlocker. Do you have other extensions that block javascript ? Those do the same thing as abdlockers since the ads are served with JavaScript
Also having this issue, with ublock disabled and JS enabled, still not being served the downloads page.
Using Firefox 52.0.2 on win10. I was able to download a previous version but I’m experiencing one of the bugs that was fixed in the latest version.
Can you please do me a favor and restart FireFox with add-ons disabled and let me know if that works ? It’s under Help > Restart with Add-ons Disabled… You may have to press Alt if the menu bar is hidden.
Also, if I may. In my experience, asking people nicely to disable Adblock works very well but preventing access to the downloads will just piss people off, just my two cents.
I think your browser might be caching the page and since it was first loaded without ads it caches it that way. Try clearing your cache after you add it to white list.
MKVCleaver is getting a couple of “suspicious/generic trojan” alerts on virustotal.com. I believe these are false positives but just writing to let you know.
This has been happening from the beginning. It’s because it’s packed with upx. There are a lot of bad antivirus software out there (I hate Symantec the most) that just don’t produce good signatures and mark anything that has been written with AutoIt and packed with upx as suspicious.
I won’t even debate how ethical is to show a big download button in your website that doesn’t download your software. Maybe you’re happy with a toolbar hijacking your browser. I’m not. The web is full of advice about how to remove that particular toolbar.
Again: check your sources for ad revenue or accept that people have the right to protect themselves from your ads.
The URL you provided is clean according to virustotal.com.
I’m not sure what fake download button or a toolbar you are referring to. Please either post images here or email me. When I’m browsing my own site, I don’t get any fake download buttons.
I’ve decided I will conduct a review of ads that are being displayed on my site to identify if there may be any security issues.
However, I just wanted to make it clear to everyone that the ads will be staying on this site and no amount of complaining will change my mind.
I will work to remove any malicious ads as soon as they are reported to me.
You do not have to disable your ad blocker as there are other places where you can get the files on the internet.
For those who are very concerned about their security, please install an antivirus and use a secure browser such as Firefox or Chrome. There are multiple free versions available for any mentioned software. Keep your Windows, anti virus, browsers and browser extensions up to date. Do a full hard drive scan at least once a week.
Personal Note: I’ve never in my life had been infected with a malware from an ad or a website as I’ve always followed my own advice.
I’m assuming you extracted AVI from an MKV file. In that case the AVI file only contains the video stream. The audio stream will need to be extracted separately, if you haven’t already done so. Then you will have to mux it into the AVI file using something like AviDeMux.
Depending on the hardware you use to play it the audio stream may need to be converted to mp3.
Drag and Drop stopped working for me after update to 0702 – 64bit. Reported via Bug Report: nothing happened, no answer, no publishing. Anybody care to help? Using Win 8.1 64bit, MKV ToolNix 15.0 & MKV Cleaver in version 0.7.0.2… BTW open MKV files via button “open mkv files to process” works fine and no probs with the extraction itself.
It’s okay Ilia… RL first. And it’s nothing really important, as long as the “open mkv files to process” button works, but I am so used to do it with drag and drop, so I get angry (’bout myself, cause I know it doesn’t work but I use D’n’D nearly all the time *stupido me*) every time I hear that “Bing” sound… So whenever you will find the time it will be fine. Great prog btw 🙂
Hi Ilia,
Is it possible MKVCleaver just to extract the unwanted (second) Audio and/or second Subtitle, but the video to stay merged with our wanted audio? Or we must afterwards merge them with AviDemux?
The way MKVCleaver works is the tracks are extracted as separate files and the original file is never modified in any way.
You then have to merge the separate track files into one by using any software you want.
I thought so Ilia, but then what software do you suggest to be used for merging and being the fastest in that, also even to be able to merge the latest HEVC compression, nevertheless it is free or premium Software? 🙂
Are you converting it to avi or keeping it as mkv ?
AviDemux is what I use when I want the files in avi format (which is very rare). If you want to keep the file in mkv format then just use mkvtoolnix-gui.exe to merge it back together.
I install the MKVCleaver but the window does not pop up when I start it , it stays in the task bar. I install the toolnix and added the extract gui in the toolnix folder along with newtonsoft.json.dll and toolnix.dll. I actually place both, GUI and GUI2 extractor. Mkv Cleaver still stays on the task bar..
Are you using a portable version ? Make sure the directory is writable to MKVCleaver. It is not advised to run MKVCleaver from a directory where another application is installed.
Please, try both portable and the installer versions.
Is not portable, is my PC. It worked fine and, one time when I start it I saw the main screen for half a second and since than it when in the side bar , does not want to show up again. It opens fine , I just can’t see the window! I uninstall and reinstall same result. How to file a bug?
I’m assuming you are using Firefox. There is a shield icon in the left corner of the address bar that you need to click on and disable tracking protection for this site. Also, under Options -> Privacy & Security -> Accept Third Party Cookies needs to be set to always.
I placed MKVCleaver_x64_v0702.exe in C:\Program Files\BDrip\Other\MKVCleaver\ and ran it. The program created its ancillary files and started normally.However when I created a shortcut (LNK) to MKVCleaver_x64_v0702.exe on the Desktop and tried to run it, the program would not start and gave “database error”.
The solution was to “Run as Administrator”! Then MKVCleaver started normally.
Everytime i try and import or drag and drop more than 3 MKVs, the gui freezes and shuts itself down, only to relaunch moments later, try and restore the files and freeze again, and loop indefinitely. Any help?
I’ve had it happen with certain files. Does it always do it with any combination of files ? Can you test with different sets of files and let me know ?
Ive tested with many different files now, its almost as if it has a mind of its own, and decides to “kill itself” anytime it wishes. I could add 1 file and it would be fine, add the same file again moments later and it will shut itself down.
Tried adding files 1 by 1, doesnt seem to solve the problem, hangs a bit and kills itself if it wants, but eventually, will get to a point where the file has loaded and you can extract stuff.
Tried adding batches of 5, 10 and 12, most unstable and (for me) has a 100% rate of crashing sometime whilst loading the files into the program.
Tried adding completely different files with different content and varying sizes and lengths, not much correlation between them and rate of killing self.
So far, ive only been able to use it to extract files one at a time, which kind of kills the point of me having downloaded this to use as a batch subtitle extraction…
Happens to me also quite regularly but only with files which have lots of different subtititle tracks included.
Just had another series of which each episode contained 22! different subtitletracks which basically means You have to try to open episode by episode with MKVCleaver before You are able to extract the required sub.
In this case subtitletracks were (All UTF-8) : English, Danish, German, Spanish, French, Indonesian, Italian, Dutch, Norwegian, Polish, Portuguese, Swedish, Turkish, Russian, Arabic, Marathi, Hindi, Bengali, Telugu, Chinese, mnc and Korean.
Ofcourse I can not tell whether MKV shuts ifself down and restarts again due to the number of title tracks or whether this happens because of certain subtitle languages which are present..
Hope this helps You.
Other than that, under normal conditions MKVCleaver really works like a charm.
Great program!
I think I have found the problem causing MKVCleaver to crash under certain conditions and usually with files containing multiple subtitles. By coincidence I noticed in the taskmanager under Windows 10 that while these crashes occur, next to the regular “windows explorer” running in the taskmanager under the category “applications” there are also multiple tasks with the same name “windows explorer” running under the category “windows-processes”
Restarting windows explorer in the taskmanager will end the multiple tasks running under “windows-processes” whereafter MKVCleaver was able to load and run and extract a batch of 10 MKV-files containing each 25 subtitles without any problem.
Before restarting windows explorer in the taskmanager this was impossible with exact the same files and I was only able to extract a subtitile file by file while MKVCleaver would stop and restart three, four times before being able to load the file.
Again,these crashes only appeared with files containing a large amount of subtitiles.
Files containing only one subtitle will not cause MKVCleaver to crash under the same conditions when extracting sutitles in batch.
Hope You this will help You in one or another way.
Also, I hope all names used in my explanation correspond to those used in the English version of Win10 since I am running another language version.
Hmm… I’ve been trying to reproduce it, however, my computers do not exhibit the same behavior.
I’m very close to releasing the next version. There are a lot of changes in regards to how MKVcleaver “talks” to mkvmerge.exe and so hopefully this issue will go away.
Unfortunately it requires an e-mail address of the recipient (which I do not have) to upload a file.
This link will take You to the download I was talking about, maybe You can get the file directly :
Would like to try out the new version to see if it fix the problem with it crashing when adding multiple files but my virus program wont let me, says that LogRotate.exe is infected with Trojan.Win32.Miner.urua.
It’s just a false positive. You have 2 options to deal with it:
1. Delete the file. Its not required for the normal operation. It just truncates logs in the database.
2. Add it as an exception in you antivirus software.
greetings,
Upon updating the MKVToolNix to the latest v35,
the installer suggests to get your MKVCleaver frontend.
So, just downloaded your latest cleaver v0.8.0
But, when trying to install the 32 bit windows version – it gets nearly all the way through install , then displays:
SETUP
Internal error: Cannot run files in 64-bit locations on this version of Windows.
then
Internal error: Expression error ‘Runtime Error (at 1:37)
The System cannot find the path specified.’
it then displays “install complete – hit OK to exit setup”
Opening the program, it complains that it cannot connect to the internet. Why it needs internet and eventually how can I allow it to connect? Unlike with other programs windows 10 didn’t ask my consent.
After many months of successful usage I hit a wall using MKVCleaver.
No matter what I try to extract I get a finished successfully message but MKVcleaver did not output any files even through it reported successful extraction.
I found similar issue solved in 5th version of the software.
Could you help me troubleshot it Ilia please.
I even reinstalled whole OS only to see it didn’t help.
Which OS are you using ?
Which version of MKVToolsNix ?
Which version of MKVCleaver ?
32 or 64 bit OS ?
If you are using the latest version of MKVCleaver:
Please turn on debug, restart MKVCleaver then extract any one file that causes the issue. After that please zip up the directory C:\Users\%username%\AppData\Local\MKVCleaver (Replace %username% with your username) and send the zip to me via email (find it in the Help menu of MKVCleaver) or upload it to ft.sapib.ca.

After that please zip up the directory C:\Users\%username%\AppData\Local\MKVCleaver (Replace %username% with your username) and send the zip to me via email (find it in the Help menu of MKVCleaver) or upload it to ft.sapib.ca.
Some files show a subtitle track, if I go into MVVToolnix-GUI it shows the file there as an SRT file. However, when I go to extract, it just skips through the files like nothing is there and although creates a SUB folder, it’s empty. Other files work perfectly fine. Basically works great when it works, doesn’t do anything when it doesn’t.
Please file a bug. Comments is not an appropriate channel for reporting issues.
Also, please send me the file that causes the issue, if possible. For large files, please go to https://ft.sapib.ca. I will need the file to test the bug.
please figure out a bug that when I encountered a error (the destination drive partition remaining space has been used up, for example) that the program didn’t give the feedback to users, at the meantime the software mini/max/close buttons are disabled and it have no responses all the time untill i end it up with the windows task manager.
my system: OS windwos 10 21H1, graphics card: nvidia quadro T 600, cpu i5-11400, motherboard intel z590
Windows 11 crashed; after that i can’t get MKVCleaver to work.
It takes all the files in n presents them nicely, as usual. but when i press extract now, nothing happens.
do I need to clear a cache or .ini file or…?

Installed previous 64-bit version. Works great! (Made donation) Want to upgrade, but not a computer guy. Downloaded the latest portable version and tried merely renaming it and replacing the older version. No go. Got error messages about being unable to open the database (or words to that effect). Tried making a new folder in C:\Program Files with a shortcut to the unrenamed executable and got the same error. Permissions don’t seem to enter into it. Is there a way to “upgrade” or should I just be content with the older version?
The installer version and the portable versions are not compatible. Please uninstall the installer version then create a new folder somewhere, for example C:\Apps\MKVcleaver, and copy the portable version there. That should do it.
I’m guessing the installer version must be WAY more difficult to continue to support. Looked around and found no other programs installed as “portable” and this leaves me with security concerns, so I think I’ll just stick with the installer version until it starts misbehaving in some way. Thanks for your lightening quick reply, though. Pretty rare, nowadays!
Ultimately, it is up to you which version you use, but I, personally, do not see any issues with using a portable version of any App. In fact, there is a whole site dedicated to making Apps portable.
Installers are more complicated to maintain and in the case of MKVcleaver not needed.
Not to beat a dead horse – and please forgive a non-computer guy – but does Windows antivirus check and monitor executables ANYWHERE they are are installed? For argument’s sake, if a bad actor modified your code where you suggested (C:\Apps\MKVcleaver) to say, steal & send my passwords somewhere, would Windows antivirus catch that? Anyway. to a non-programmer/expert, it seems so much more logical and organized to have everything in C:\Program Files (X86) & C:\Program Files. I currently have 168 programs installed, and they’re all there.
Windows Defender should be checking all folders on C:\ drive. I cannot make a claim about your specific setup though.
As far as malware and password stealing, you have it somewhat upside down. Both, installers and portable apps are capable of stealing password and other info, however, if an installer is infected with malware it would be a much, much worse situation.
In order to install software into C:\Program Files, Admin right must be given to an installer. In that case, should malware be present in that installer, well, you just handed the keys to the kingdom to some guy/gal somewhere in the world.
On the other hand, no portable app should ever request Admin rights to work (if one does, that’s a red flag right there). So if a portable app is infected with malware and, for argument’s sake, doesn’t get Admin rights, it can only do damage to your user profile and files you have access to as a user. In such a case, it would be a fairly trivial task to delete a user’s profile and start from scratch then restore important files (provided you do regular backups or sync to the cloud).
This is why it is far more important to trust the source site (download location) of the downloaded file and check the checksum/crypto signature to make sure no part of software was modified.
I always post a MD5 checksum for the latest version. Verifying that checksum after downloading MKVcleaver would be the best way to make sure it was not modified by someone else.
Hi,
New error during extracting: The JSON option file mkv_cmd.json contains an error : JSON options files must contain an array composed only of JSON strings
Mkvextract.exe and/or Mkvmerge.exe was not found.
Make sure that the path to the files is correct.

Make sure you tell MKVCleaver where those files are. Click on Locate MKVToolsnix button.
First things first, thanks for your effort and a truly quality product. Next, I’ve noticed that suddenly MKVCleaver is SLOW to launch….Like 30 to 45 seconds slow. I didn’t seem to take that long when I first installed it. Is there something that could be gumming up the startup that I could possible clean up?
Looks like automatic update check is causing this. I will fix it in the next version, however, for now, please disable update check in the settings.

Check your OS partition for errors as I’ve seen NTFS journal errors cause very slow systems.
And finally, a corrupt MKV file will do that too.
this program is amazing, idk what i’d do without it.
Can you make a program like this, but instead of extracting it will batch remux things?
i’ve only found one so far that remuxes subtitles (called cenko) but its really basic and also removes fonts when it does it.
Thank you for a positive comment. I’m glad you like it.
I would consider making a GUI for muxing in the future, but first, I would like to know what is wrong with the mktoolnix-gui.exe that comes with the MKVTollNix package ? It has batch job mode.
Yeah it has a batch mode, but that’s only after you’ve done all the work for each individual file yourself.
so i mean it kind of defeats the point.
OK. I will look into it. I can’t really promise anything, especially about an ETA. It all depends on how much work is involved.
Muxing MKVs is a bit more complex task than taking them apart.
What about this one ?
https://bitbucket.org/sstanford/bulk-mkv-muxer
eh it requires a ton of manual work to remux the files.
nothing like your program that you just select specific boxes and it takes care of the rest.
Yeah, yeah, I know that you have to pay for your site…but you really don’t need to be such a dick about it. There *are* other ways to get the money. People use ad blocking software for a reason, and you apparently don’t understand what the reason is. Since you’re such an annoying little prick, I find it worth the bother to comment. Eat shit and die, you fucking little shit. Grow up and get a fucking life, punk. It isn’t like your puny GUI is the most wonderful and necessary program out there, and, if it’s such a big deal to you that people not use your bandwidth for downloading it, there sure as fuck ARE places that will host the fucking thing. If you can’t think any better than this, then your crap is probably not worth my time anyway. However, I will take a look at it, I won’t whitelist your sorry ass, and I’ll STILL download it from your site. I’m not going to tell you how I do it, but you’re not the only greedy little bastard attempting to block people this way…and I’ve found that it isn’t at all difficult to bypass your so-called blocker. Have a nice fucking day, kid.

I’ve got AdBlocker disabled on this site but the site is too effin stupid to know the difference !
I’m assuming you reloaded the page after disabling the AdBlocker. Do you have other extensions that block javascript ? Those do the same thing as abdlockers since the ads are served with JavaScript
Also having this issue, with ublock disabled and JS enabled, still not being served the downloads page.
Using Firefox 52.0.2 on win10. I was able to download a previous version but I’m experiencing one of the bugs that was fixed in the latest version.
Can you please do me a favor and restart FireFox with add-ons disabled and let me know if that works ? It’s under Help > Restart with Add-ons Disabled… You may have to press Alt if the menu bar is hidden.
Thanks.
Or if you’re in a hurry, you can use Internet Explorer or download it from Video Help.

Also, what browser are you using ? It’s so I can test it, ’cause it’s working for me in FireFox when I disable the AdBlocker.
I was able to reproduce this behavior with custom DNS and when using dnscrypt-proxy. Some ad domains get filtered out.

Hi,
I will look into the why it still detecting you as using the AdBlock.
I will also add alternative download link to the block message, however, the block itself will stay in place.
I think your browser might be caching the page and since it was first loaded without ads it caches it that way. Try clearing your cache after you add it to white list.

Hello,
I cannot hear anything when I play the avi file. How can I get the audio to play in the movie?
I’m assuming you extracted AVI from an MKV file. In that case the AVI file only contains the video stream. The audio stream will need to be extracted separately, if you haven’t already done so. Then you will have to mux it into the AVI file using something like AviDeMux.
Depending on the hardware you use to play it the audio stream may need to be converted to mp3.
Drag and Drop stopped working for me after update to 0702 – 64bit. Reported via Bug Report: nothing happened, no answer, no publishing. Anybody care to help? Using Win 8.1 64bit, MKV ToolNix 15.0 & MKV Cleaver in version 0.7.0.2… BTW open MKV files via button “open mkv files to process” works fine and no probs with the extraction itself.
My apologies. I have to approve when someone posts anything for the first time. I was busy with personal matters.
It is OK to email me if you don’t get a response in a timely manner.
It’s okay Ilia… RL first. And it’s nothing really important, as long as the “open mkv files to process” button works, but I am so used to do it with drag and drop, so I get angry (’bout myself, cause I know it doesn’t work but I use D’n’D nearly all the time *stupido me*) every time I hear that “Bing” sound… So whenever you will find the time it will be fine. Great prog btw 🙂
Hi Ilia,
Is it possible MKVCleaver just to extract the unwanted (second) Audio and/or second Subtitle, but the video to stay merged with our wanted audio? Or we must afterwards merge them with AviDemux?
Hi,
The way MKVCleaver works is the tracks are extracted as separate files and the original file is never modified in any way.
You then have to merge the separate track files into one by using any software you want.
Hope that helps.
Thanks.
I thought so Ilia, but then what software do you suggest to be used for merging and being the fastest in that, also even to be able to merge the latest HEVC compression, nevertheless it is free or premium Software? 🙂
Are you converting it to avi or keeping it as mkv ?
AviDemux is what I use when I want the files in avi format (which is very rare). If you want to keep the file in mkv format then just use mkvtoolnix-gui.exe to merge it back together.
Thanks, I prefer keeping in mkv.
I install the MKVCleaver but the window does not pop up when I start it , it stays in the task bar. I install the toolnix and added the extract gui in the toolnix folder along with newtonsoft.json.dll and toolnix.dll. I actually place both, GUI and GUI2 extractor. Mkv Cleaver still stays on the task bar..
Are you using a portable version ? Make sure the directory is writable to MKVCleaver. It is not advised to run MKVCleaver from a directory where another application is installed.
Please, try both portable and the installer versions.
Please file a bug if the issue persists.
Is not portable, is my PC. It worked fine and, one time when I start it I saw the main screen for half a second and since than it when in the side bar , does not want to show up again. It opens fine , I just can’t see the window! I uninstall and reinstall same result. How to file a bug?
No, I meant if you were using MKVCleaver portable or the installer version (not what type of computer…).
Please install MKVCleaver installer version before filing a bug.
Then if it still not working, file a bug here: https://blogs.sapib.ca/apps/bugs-requests/
AdBlock is “Green”, but you still indicate that i have to use the alternative download…
I’m assuming you are using Firefox. There is a shield icon in the left corner of the address bar that you need to click on and disable tracking protection for this site. Also, under Options -> Privacy & Security -> Accept Third Party Cookies needs to be set to always.
I placed MKVCleaver_x64_v0702.exe in C:\Program Files\BDrip\Other\MKVCleaver\ and ran it. The program created its ancillary files and started normally.However when I created a shortcut (LNK) to MKVCleaver_x64_v0702.exe on the Desktop and tried to run it, the program would not start and gave “database error”.
The solution was to “Run as Administrator”! Then MKVCleaver started normally.
I’m glad it worked for you.
However, there is no need to do that. The best solution is to install the installer version of MKVCleaver.
If you want to continue to run the portable version then please move it to a directory where Admin rights are not needed for writing.
Everytime i try and import or drag and drop more than 3 MKVs, the gui freezes and shuts itself down, only to relaunch moments later, try and restore the files and freeze again, and loop indefinitely. Any help?
I’ve had it happen with certain files. Does it always do it with any combination of files ? Can you test with different sets of files and let me know ?
Ive tested with many different files now, its almost as if it has a mind of its own, and decides to “kill itself” anytime it wishes. I could add 1 file and it would be fine, add the same file again moments later and it will shut itself down.
Tried adding files 1 by 1, doesnt seem to solve the problem, hangs a bit and kills itself if it wants, but eventually, will get to a point where the file has loaded and you can extract stuff.
Tried adding batches of 5, 10 and 12, most unstable and (for me) has a 100% rate of crashing sometime whilst loading the files into the program.
Tried adding completely different files with different content and varying sizes and lengths, not much correlation between them and rate of killing self.
So far, ive only been able to use it to extract files one at a time, which kind of kills the point of me having downloaded this to use as a batch subtitle extraction…
Happens to me also quite regularly but only with files which have lots of different subtititle tracks included.
Just had another series of which each episode contained 22! different subtitletracks which basically means You have to try to open episode by episode with MKVCleaver before You are able to extract the required sub.
In this case subtitletracks were (All UTF-8) : English, Danish, German, Spanish, French, Indonesian, Italian, Dutch, Norwegian, Polish, Portuguese, Swedish, Turkish, Russian, Arabic, Marathi, Hindi, Bengali, Telugu, Chinese, mnc and Korean.
Ofcourse I can not tell whether MKV shuts ifself down and restarts again due to the number of title tracks or whether this happens because of certain subtitle languages which are present..
Hope this helps You.
Other than that, under normal conditions MKVCleaver really works like a charm.
Great program!
Would you be able to upload a file that cuases MKVCleaver to crash ?
It is quite hard to reproduce this error if I don’t know the exact cause.
Please go to https://ft.sapib.ca
Hi again,
I think I have found the problem causing MKVCleaver to crash under certain conditions and usually with files containing multiple subtitles. By coincidence I noticed in the taskmanager under Windows 10 that while these crashes occur, next to the regular “windows explorer” running in the taskmanager under the category “applications” there are also multiple tasks with the same name “windows explorer” running under the category “windows-processes”
Restarting windows explorer in the taskmanager will end the multiple tasks running under “windows-processes” whereafter MKVCleaver was able to load and run and extract a batch of 10 MKV-files containing each 25 subtitles without any problem.
Before restarting windows explorer in the taskmanager this was impossible with exact the same files and I was only able to extract a subtitile file by file while MKVCleaver would stop and restart three, four times before being able to load the file.
Again,these crashes only appeared with files containing a large amount of subtitiles.
Files containing only one subtitle will not cause MKVCleaver to crash under the same conditions when extracting sutitles in batch.
Hope You this will help You in one or another way.
Also, I hope all names used in my explanation correspond to those used in the English version of Win10 since I am running another language version.
Hmm… I’ve been trying to reproduce it, however, my computers do not exhibit the same behavior.
I’m very close to releasing the next version. There are a lot of changes in regards to how MKVcleaver “talks” to mkvmerge.exe and so hopefully this issue will go away.
Hi,
I disabled my adblock software (AdBlock Plus) on your site but still get the warning and cannot download.
Please improve your checking technique.
Are you using FireFox ?
You must allow 3rd party cookies (you can change it back later) and also disable the tracking protection for my site.
If you have any other add-ons that block cookies they are also need to be adjusted.
Unfortunately it requires an e-mail address of the recipient (which I do not have) to upload a file.
This link will take You to the download I was talking about, maybe You can get the file directly :
https://rarbgmirror.org/torrent/agnzv7b
Episode 2 is the smallest with 1,87 GB and all files have 22 different subtitles.
Would like to try out the new version to see if it fix the problem with it crashing when adding multiple files but my virus program wont let me, says that LogRotate.exe is infected with Trojan.Win32.Miner.urua.
A new source of income or just a mistake?
It’s just a false positive. You have 2 options to deal with it:
1. Delete the file. Its not required for the normal operation. It just truncates logs in the database.
2. Add it as an exception in you antivirus software.
Thanks.
greetings,
Upon updating the MKVToolNix to the latest v35,
the installer suggests to get your MKVCleaver frontend.
So, just downloaded your latest cleaver v0.8.0
But, when trying to install the 32 bit windows version – it gets nearly all the way through install , then displays:
SETUP
Internal error: Cannot run files in 64-bit locations on this version of Windows.
then
Internal error: Expression error ‘Runtime Error (at 1:37)
The System cannot find the path specified.’
it then displays “install complete – hit OK to exit setup”
but it Has Not Installed anything…
OS=Win7Sp1 32Bit
I will check it.
Please file a bug next time.
Thx.
The installer is now fixed. Thank you for reporting this.
Opening the program, it complains that it cannot connect to the internet. Why it needs internet and eventually how can I allow it to connect? Unlike with other programs windows 10 didn’t ask my consent.
It only needs internet for checking for updates. You can disable this in the settings.
I’m not sure which security software you are using. You may need to allow MKVCleaver access to the internet in your firewall settings.
After many months of successful usage I hit a wall using MKVCleaver.
No matter what I try to extract I get a finished successfully message but MKVcleaver did not output any files even through it reported successful extraction.
I found similar issue solved in 5th version of the software.
Could you help me troubleshot it Ilia please.
I even reinstalled whole OS only to see it didn’t help.
Which OS are you using ?
Which version of MKVToolsNix ?
Which version of MKVCleaver ?
32 or 64 bit OS ?
If you are using the latest version of MKVCleaver:
Please turn on debug, restart MKVCleaver then extract any one file that causes the issue. After that please zip up the directory C:\Users\%username%\AppData\Local\MKVCleaver (Replace %username% with your username) and send the zip to me via email (find it in the Help menu of MKVCleaver) or upload it to ft.sapib.ca.
Thx.
Thank you for quick response.

Some files show a subtitle track, if I go into MVVToolnix-GUI it shows the file there as an SRT file. However, when I go to extract, it just skips through the files like nothing is there and although creates a SUB folder, it’s empty. Other files work perfectly fine. Basically works great when it works, doesn’t do anything when it doesn’t.
Please file a bug. Comments is not an appropriate channel for reporting issues.
Also, please send me the file that causes the issue, if possible. For large files, please go to https://ft.sapib.ca. I will need the file to test the bug.
please figure out a bug that when I encountered a error (the destination drive partition remaining space has been used up, for example) that the program didn’t give the feedback to users, at the meantime the software mini/max/close buttons are disabled and it have no responses all the time untill i end it up with the windows task manager.
my system: OS windwos 10 21H1, graphics card: nvidia quadro T 600, cpu i5-11400, motherboard intel z590
I would have to probably check free space before each extraction. I will look into it.
your app is full of virus as of today. probably u need to upload the clean version of the app.
please check virustotal report – https://www.virustotal.com/gui/file/bcd94679675d9e039c88b121a83e575d0be4bc99fb3b289aff04f221e5a70fb9
thanks
If you check the hash and it matches the one on the download page on this site, then it’s safe. VirusTotal report is full of false positives.
Alternatively, you can compile it from source.
V0.8.0.0 Continually Generates Errors if you are still working on it.
Please file a bug report.
I will take a look once you can provide more information.
Windows 11 crashed; after that i can’t get MKVCleaver to work.
It takes all the files in n presents them nicely, as usual. but when i press extract now, nothing happens.
do I need to clear a cache or .ini file or…?
Try deleting all MKVCleaver files. Re-download the executable and try again.
If that doesn’t work, enable debug and execute all the actions. Send me the debug log.
Hi, where can I find installation file for v 0.8.0.1 ?
Sorry, all installers are deprecated. Only the portable versions will be published from now on.
Hi, I reinstalled version 0.8.0.1 and then 0.8.0.0 but I just get “Extraction successful” but no file. Below is the log

Hi Neutr0n.
Please enable debug and run the extraction on any file that causes the issue again, then send me the debug log please (email is preferred).
The log file will be in the same directory as MKVCleaver executable.
Hi what email address do I send it to pls?

Installed previous 64-bit version. Works great! (Made donation) Want to upgrade, but not a computer guy. Downloaded the latest portable version and tried merely renaming it and replacing the older version. No go. Got error messages about being unable to open the database (or words to that effect). Tried making a new folder in C:\Program Files with a shortcut to the unrenamed executable and got the same error. Permissions don’t seem to enter into it. Is there a way to “upgrade” or should I just be content with the older version?
Hi
Your donation is much appreciated.
The installer version and the portable versions are not compatible. Please uninstall the installer version then create a new folder somewhere, for example C:\Apps\MKVcleaver, and copy the portable version there. That should do it.
I’m guessing the installer version must be WAY more difficult to continue to support. Looked around and found no other programs installed as “portable” and this leaves me with security concerns, so I think I’ll just stick with the installer version until it starts misbehaving in some way. Thanks for your lightening quick reply, though. Pretty rare, nowadays!
Hi
Ultimately, it is up to you which version you use, but I, personally, do not see any issues with using a portable version of any App. In fact, there is a whole site dedicated to making Apps portable.
Installers are more complicated to maintain and in the case of MKVcleaver not needed.
Not to beat a dead horse – and please forgive a non-computer guy – but does Windows antivirus check and monitor executables ANYWHERE they are are installed? For argument’s sake, if a bad actor modified your code where you suggested (C:\Apps\MKVcleaver) to say, steal & send my passwords somewhere, would Windows antivirus catch that? Anyway. to a non-programmer/expert, it seems so much more logical and organized to have everything in C:\Program Files (X86) & C:\Program Files. I currently have 168 programs installed, and they’re all there.
Windows Defender should be checking all folders on C:\ drive. I cannot make a claim about your specific setup though.
As far as malware and password stealing, you have it somewhat upside down. Both, installers and portable apps are capable of stealing password and other info, however, if an installer is infected with malware it would be a much, much worse situation.
In order to install software into C:\Program Files, Admin right must be given to an installer. In that case, should malware be present in that installer, well, you just handed the keys to the kingdom to some guy/gal somewhere in the world.
On the other hand, no portable app should ever request Admin rights to work (if one does, that’s a red flag right there). So if a portable app is infected with malware and, for argument’s sake, doesn’t get Admin rights, it can only do damage to your user profile and files you have access to as a user. In such a case, it would be a fairly trivial task to delete a user’s profile and start from scratch then restore important files (provided you do regular backups or sync to the cloud).
This is why it is far more important to trust the source site (download location) of the downloaded file and check the checksum/crypto signature to make sure no part of software was modified.
I always post a MD5 checksum for the latest version. Verifying that checksum after downloading MKVcleaver would be the best way to make sure it was not modified by someone else.
Hi,
Error with last version 0.8.0.2 : can’t load mediainfo DLL !?
Please either install MediaInfo package on your system or download MediaInfo DLL and place it in the same directory as MKVCleaver is being run in.
MediaInfo Package v25.10
MediaInfo DLL v25.10 Zip
Hi,
New error during extracting: The JSON option file mkv_cmd.json contains an error : JSON options files must contain an array composed only of JSON strings
Hmm. Possibly a bug.
Would you mind filing a bug ? If you could provide a debug log and a file that causes the error, it would make troubleshooting easier.
BTW, does this happen with all the files or just some ?
