MKV to AVI

Anyone know a free program that can convert and MKV file to a AVI? I had this one but unless you purchase it it leaves a big logo on like the middle of the video

I haven't tried this myself, but you can probably load them ino VirtualDubMod, make sure direct stream copy is selected for both the video and the audio stream, and use save as avi.

Now, for the obligatory statements: Using downloaded footage to make an AMV is very bad. The end-product will look shitty, your editing software will keep crashing and the original artists will die of starvation. Buy the DVD's if that's at all possible, or no-one will take your hard work seriously. If it was not your intention do edit with these mkv's, ignore my rambling.

Yes, that works, as long as it's not ISO-AVC (possibly ISO-MPEG4, also) or RealMedia or any other weird non-VFW format. Otherwise VDubMod won't even be able to process it. MKVExtract may be able to, but AFAIK, it suffers from the same VFW weakness that VDub does.

Thanks for the help let me give this a shot.

If there's a DirectShow splitter and decoder for the container + codec being used, AVISynth's DirectShowSource can usually handle it. Speed isn't great but it works for transcoding.

For some reason, whenever I try to use DirectShowSource, the audio sync gets skewed. It doesn't matter what type of video file it is - MKV, RM, WMV, etc. - even if the file has a constant framerate. Graphedit doesn't seem to have this error, but trying to open the graph file through DirectShowSource screws up the sync. If only it was possible to use TMPGEnc's DirectShow loader with AVISynth or Graphedit files without using DirectShowSource, there wouldn't be a problem.

And on the subject of extracting, is there anything that can demux a raw ISO-AVC stream from a Matroska file? Especially one that I believe is damaged, since Haali's splitter won't even give an audio or video output when I try to render it through Graphedit.
