I'm having a really strange issue with handbrake currently. I tried to convert an .avi file (xvid, ac3). It works, but when watching the created file (.mp4, h264, ac3) I noticed that the audio was out of sync with the video. I looked at the source and the created video and noticed, that the source video has like 2 seconds of just black at the very beginning. the video handbrake created does not have that black screen - and that's what causes the audio to be out of sync, because the audio handbrake creates HAS that 2 second "nothing" at the beginning.
Now for the strange thing: I tried to simply delete the black screens at the beginning of the source file with virtualdub. The length of the video vdub created was 2 seconds shorter than the original video, but I couldn't notice any difference in the video stream. the audio began 2 seconds later (so without 2 seconds of nothing at the beginning), but the video was still the same. 2 seconds black, then it started - and that even though I cut out the black screens in vdub! it doesn't matter how often I repeat that operation. the audio gets shortened by 2 seconds, and even though I cut out the blackness in the video when I watch the video there it is.
any ideas on how to solve this? could this be a broken header or something special with the avi file? is there maybe any option in handbrake to deal with this kind of video?
thanks!
PS: I will give you a activity log, but unfortunatly I had another video in my queue so it deleted the log - will post it asap.
