[MEncoder-users] adding harddup's after the fact...

So basically I encoded an mpeg stream without '-vf harddup' and am
regretting it.  The file is in an AVI with h264 video and ac3 audio and I'm
trying to convert it to mp4/264/aac (so I can play it in quicktime).

I've managed go get everything dumped, re-encoded and remuxed the way I
want, but I have a sync issue.  The video is going much faster than the
audio.  (Is this because all of those 0-byte frames got dropped when the
remuxing occured??)

So, my original AVI file plays fine, which tells me that those 0-byte
'duplicate' frames must be sitting there acting like duplicates, waiting to
be blown away by the resmuxer and screwing me over...  Is there any way I
can convert all of those fake duplicate frames to hard dups **without
re-encoding the video** so that when I do dump and remux them that the sync
issue doesn't happen?

Does that all make sense?

Thanks!
