[FFmpeg-user] Keeping A/V sync during telecine

[Carl Zwanzig]

Hello,

Using a handy VOB, I did a conversion and created a pair of files of the 
first ~2 minutes. The lack of sync is quite apparent in the last 15 seconds.

Original- https://www.dropbox.com/s/l4mw62oz62xbph3/tb-orig.mpg?dl=0
Processed- https://www.dropbox.com/s/abnockk5wht6oeg/tb-proc.mpg?dl=0
(I'll leave these up for maybe a week)

Completely uneducated guessing--
If the actual audio stream doesn't start with the video, could something is 
messing with the timestamps (muxer?) instead of passing them through? I'm 
not sure how to look at them.

Would it be possible to sort of force things by mixing silence from another 
source with the clip's audio stream? I have no idea how the filter graph for 
that would go.

Thanks,

z!
