How to convert from .mkv to .avi?

[omegaevolution]

don´t know if this is the correct thread to post this, still I have a pack of videos with a .mkv codec and I want to convert them to .avi for better use in my Vegas, the problem is that I don´t know how to do it, if anyone know please help me.

PS: if it can be converted with VirtualDub that would rock, still I need any method possible.

thanks in advance

VDubMod can do it. I've never messed with editing .mkv's before for though, so I can't really tell you how to fine tune it.

You can load them through an avisynth script using DirectShowSource(), then open that up in virtualdub and save it to a lossless codec like Lagarith.

wow I will try that out, thanks

I use.... hmm... what do I use.... River Past Video Cleaner. It basically takes the avi OUT of the mkv container and SOME avi's are raws!! So if you got it from a good fansubber (like I got my SHIT footage for my Corn segment, with apologies to Zarxrax for riding on his wave of popularity ;p) than you'll get it without subtitles at all! ;p
Oh, but the demo version of Riverpast leaves a tiney watermark.... Tere's other 'mkv rippers' but I can't get any of them to work

.mkv codec

excuse me for a second *patches bleeding eyes*... there... now:

Look no further.

Here's how you do it:

1: open the MKV/OGM in virtualdubmod,
2: go to the "streams" tab, deactivate all audio,
3: then go to the "video" tab and select "Direct Stream Copy"
4: now File>Save As... and save as an AVI.

You'll have the video with no audio in AVI. If the file doesn't open in VDM, load it through a directshowsource AVS with the killaudio() command.

IF IT STILL DOESN'T WORK, you need to convert to lossless:
1: Download HuffYUV.
2: Open VirtualDubMod again, deactivate the audio, but this time select "Fast Recompress" on the video tab.
3: Video>Compression, select HuffYUV.
4: File>Save As...

Done. You have a huge lossless AVI file. If it's too big, then save clips rather than entire episodes.

it says:

Avisynth open failure:
DirectShowSource: Could not open as video or audio

Video returned: "DirectShowSource could not open file C:\blablabla.mkv: it can not be reproduced. Format is not compatible."

same happened with the audio, do I need a codec too to open the file in VDB?

get VirtualDubMod
it was made specifically for importing other filetypes (like .mkv)...and has a few other features too.

if you don't have a VFW codec for the .mkv file extension (format or container? I don't know) you should get one. If you have FFDshow you should be fine. otherwise, you can google it. (it comes in the amvapp, matroska pack and CCCP)

This only works if the video was encoded using VFW. If you're looking at ISO-MPEG4 or ISO-AVC, you have to load it in through AviSynth/DirectShowSource (unless of course you want to go to the trouble of reordering the frames - MKVExtract should work okay with ISO-MPEG4, but if it's ISO-AVC you need to extract the raw .264 file using MKVExtract's command-line and then run it through avc2avi). Still, VDubMod does have the Open via AviSynth option in the Open dialog box that lets you set DirectShowSource and open the file that way.
