MKV to anything else

[y4m4]

I have a whole bunch of MKV files I need to convert to something else. I'm not going to be picky about what format. I've tried VDM, tried Demuxing the audio tried not demuxing the audio, all that stuff. The only program I have found that will actually come close to what I need is River Past Video CLeaner. This program works very well for all the other formats I convert except MKVs. When I convert a MKV with this program to anything else it has a horrible 4 second audio delay. I have even tried AVIMux_GUI to put a -4000 or -3000 or -3500 and so on delay on the audio and that kinda works but it only seems to work for the first few minutes. I have tried TMPGenc and that gets the job done except I am not smart enough to make it batch encode and it takes a very long time to convert the files.

Anyone have any suggestions?

I have searched and search (google and these forums) and have found quite a few threads but they all say the same thing, use VDM and demux the audio then make the audio-less avi and then enconde them together. For some reason I cannot get it to work. I demux the audio and when I try and add it to the avi VDM will not open the audio. Maybe I don't know what format to save the demuxed audio as. I have also tried using VDM to save the audio stream as a WAV and that doesn't work. I ahve also tried saving it as a AVI in VDM and disabling the audio track and subs I don't want and then use full processing mode with MP3 audio to try and make it into a AVI and that did not work. I also tried that with uncompressed audio and nothing.

Thanks

Did you try GraphEdit as well? Render the file with graphedit, disconnect everything after the mkv splitter and add an avi mux filter where you connect the streams to (at least video and audio).
After that filter you should be able to put a filewriter filter whcih then saves the file to disk.

At least worth a try. You can set the audio delay as well if necessary in the avi muxer if I remember correctly.

y4m4: If putting a delay works only for the first few minutes, then either your video framerate is b0rked, or file needs more "treatment"

In the 2nd case, you might try to split the file into pieces of a few minutes and sync each one separately

In the first case, do this:
Try this not-yet-ready-AVI-Mux GUI 1.16.9 (http://www-user.tu-chemnitz.de/~noe/amg.zip). It will allow to mux MKV->AVI if no audio stream is selected and if there are no crappy gaps in the video stream. Then, extract the audio streams as well and mux the result to an AVI file. Put a delay, so that the beginning is in sync, and then play around with the framerate (in AVI-Mux GUI: load a file you want to change the framerate of, rightclick -> information -> rightclick)

Subtitles can be extracted using mkvextract.
