I have an odd problem, I searched thru the forums and I'm sure the answer is out there but I can't seem to find it. I also posted this first in the wrong forum, so I am trying in the right one now ;)
I was converting an AVI to an MPEG, the video conversion went fine. (roughly 52 min of video) I then extracted the audio WAV with Vdub and converted the wav to ac3 in besweet. Problem is, the ac3 that gets output is about 10 min too long. (about 1 hr, 2 min.) It stretches the audio badly (slow, low pitch). Not sure why. The audio wav out of Vdub still sounds fine, so it is something happening during the transcode in besweet. Is there some way to fix this problem?
It's not PAL. I'm doing NTSC at 29.97. I did this to several other AVIs and they worked fine but this one seems to be made differently. As near as I can tell almost everything matches up except one small difference.
the standard I've been working with is:
384 kb/s (6 ch) CBR 48000 Hz source. (i.e. almost a straight changeover to AC3 in besweet)
The one causing problems is:
384 kb/s (5 ch) CBR 48000 Hz
Apparently it is missing one of the 5.1 channels. (?) Regardless, looking at the others I've done there are a few that had the same missing channel yet did not cause this problem.
edit: so I fixed the time problem (not sure how, just reencoded with a bunch of different settings) but the wierd low pitch still exists. It sounds like everyone is talking in a deep bass and there is intermitent static. Anyone?
