After your works done in VDub, export video AVI format with lossless codecs and after encode MP4 this video. I want to rip the sound track from the avi/mpg file using VirtualDub 1.7.8 (Build 28346). Open VirtualDub, import video, after choose « Audio > Audio from other file » and select WAV file. I can play that file with Windows Media Player (v.11). I think what we need here is a more helpful error message. I have an AVI file which I successfully converted from flv format to avi/mpg format using avs Video Converter (v.6) trial version. VirtualDub's MPEG-1 parser is intolerant to errors compared to its AVI parser, so unfortunately there is no easy solution to the latter problem. Fast recompress now works even if no decompressor is present (i.e. In theory, if you've installed an ACM codec for MPEG Layer II, then you shouldn't receive an error with the box checked. It means one of two possibilities: You have an MPEG-2 file, which VirtualDub doesn't support You have an MPEG-1 file that is corrupted. That turned out to cause the problem with VirtualDub destroying the audio sync. What the checkbox really does is it makes the MPEG audio parser behave exactly like the AVI and ASF audio parsers, both of which require external ACM codecs to decompress their audio streams. My checkbox is a dirty kludge to get around that, at least for audio. Unfortunately, this design makes Direct Stream Copy of MPEG audio and video impossible. By someone's request, I recently moved it to the Preferences dialog and made it remember its setting.īecause of the way the MPEG module is structured, MPEG audio and video are always decompressed before being sent through the rest of VirtualDub's pipeline. It defaulted to unchecked, and you had to check it for each and every MPEG if you wanted to use it. It was originally "hidden" in the extended open options dialog for MPEG files. That option has a long history of confusing people.
