I encoded a movie (from DVD, ripped with DVDDecrypter) with Autogordianknot. (newest versions of both programs) I understand that AutoGK uses vdubmod as one of its most important sub-programs.
As this was a music video, and the music was especially important to it, I tried to increase the quality of the music for the video, as much as might be possible in a small video for the Pocket PC, like I was making. For such a movie keeping the AC3 sound would not be at all practical. I chose the option of VBR MP3 sound in AutoGK. (Theoretically VBR should produce better sound quality than CBR.) I also raised the bit rate from the default 128 kbps to 192 kbps.
After AutoGK was finished making the AVI, I tried playing it with Media Player Classic. It played fine. The music sounded good, was well in sync with the video, etc.
I thought I might want to do a little editing, so I then opened the movie with Vdubmod. (In fact the same one AutoGK had used in making the movie, located in a sub-folder of the AutoGK folder.)
I was surprised, that Vdubmod had a severe problem in opening the file. I would immediately get an error message regarding the VBR, asking me if I wanted to change it to CBR. I clicked on "NO'. I tried playing the movie in vdubmod, and the sound was strange, and way out of sync with the video. Then vdubmod crashed. I tried several times, always the same result. I tried also in regular vdub (not mod,) with the same result.
What is the problem here? Why do vdubmod and vdub have a major problem with this AVI file, although vdubmod helped make it? Can they not open a video with VBR MP3 sound? Or is it the 192 kbps bit rate? Is VBR not a good idea in video encoding?
