Lip Sync Super 8 Film

Hello

I have a job to convert analog Super 8 film. The subjects were filmed and the sessions recorded on cassette tape. What I must do is sync the audio to subject. In this sample I can as is evident in the start of the segment sync the audio to the subjects lips. Later the audio slips out of sync.

I started at the beginning of this 19minute film recorded 1971 where Margarete introduces herself 'I am Margarate...." and using the Alt + arrow key moved the audio left and right to find her lip sync.

Is there a method in Audtion CS6 where the whole of the audio matches the speaker? I think I am missing the obvious and seek advice here in this forum.

Thanks

I'm afraid that there's no easy way to do this, and you are unlikely to be able to get it absolutely lip-synced, as the sources were completely and utterly unlinked to each other.

Generally you look for 'syncing' points, and measure (on the video) exactly how long it is between them. Then you locate the same points on the audio, select them and use Audition's Stretch and Pitch tool in Waveform to match the duration to the time you've got from the video. You probably won't be able to do it over a very long period, and you'll have to redo it in sections.

Oh, and the tracking control on your video playback machine needs adjusting!

Thanks for the insight.

It is the tracking control - how to I adjust? This is new, thanks!

This drifts out gradually on your clip. On the video playback machine somewhere (possibly hidden under a panel) you'll find a 'tracking' control. What this does is to attempt to line up the scanning head on your machine with the way that the head scanned on the machine it was recorded on. Sometimes this is a complete failure, especially if the machine a track was recorded on is significantly out of alignment, and you end up having to adjust it frequently as you digitise. What you are looking at is all those shimmering lines in the middle of the picture, and minimising them. Other things that I can tell from this are that the tape guides and possibly the sync head need cleaning! That's not a job for the faint-hearted, but often you can improve things a bit, for a while at least, by running a head cleaning tape through the machine.

Do you have any idea what this was originally recorded on? It's also possible that if this is a copy from an original that the errors may have been introduced at the original copy stage, and there's nothing you can do about that; it's then built into your copy.

The reason, incidentally, that your sound drifts so far is that the speed specification on cassette recorders was very generous; you could easily get 2% errors regularly, so if you don't play the tape on the machine that it was recorded on, all bets are completely off, as this could easily get compounded to about 4% across two machines, and that's 2-3 seconds per minute!
