Resynching new audio w/old video?

[funsoul]

Hi folks

I've got a bunch of older concert vids (and other vids with poor audio) that am in the process of capturing and was wondering if there are any good step-by-step guides that explain how to replace the existing audio with new (better quality) audio? The replacing of the tracks is easy....getting the new audio synched with the video is much less so

Any tips, hints, guidance, urls, etc would be appreciated (including which choice of software) would be much appreciated.

It ranges from "very difficult" to "impossible". The problem is that the video is recorded at different rates (29.97fps for a while, then 29.965fps for a while, then 29.978fps for a while), while the new audio is most likely recorded at a constant timebase. That alone makes syncing very difficult.

What you can do, is import both audios on a mixer timeline (I use the COOLEDIT 2000 four channel mixer), then stretch and compress the timeline of the new audio to match the original - a LOT of work, but this is the only way that I know that can do what you want.

Or, if the variations are not that large, sync the new audio at a single point, and let the rest drift in and out of sync.

Thanks SLK001....thought it'd go something like that. Will give it a try once the new soundcard arrives (so I can grab the replacement audio from DAT's).
