Synchronizing Video Clips basing on the audio track
Hi,
The following image represents my timeline:
===============================================================
| FIRST CLIP | | SECOND CLIP |
===============================================================
--- LONG VIDEO CLIP HERE ---
===============================================================
I have a long video clip and a series of small video clips that have been recorded using two different cameras.
CAMERA 1: LONG VIDEO CLIP
CAMERA 2: FIRST CLIP, SECOND CLIPThe “long video clip” will occupe the whole screen in the final video, while the “first” and “second” clips will appear on a corner, when needed.
Since the audio is in common between the long and the tiny video clips, what I’m trying to do is to put the “first” and the “second” clip in “the right place”. so their audio overlaps with the one belonging to the “long video clip”.
Right now, I’m doing this manually, searching for the right frame for every clip. Any chance to do this more quickly/effectively?
Hope the problem is clear enough. If not, I’ll try to explain it a bit more.
Thanks.

Hi Roberto,
I have to do this all the time when I edit stage shows. Obviously the way you should do it is with a clapboard.
The best way I have found to sync clips is to find either an audio ‘pop’ (sharp audio sound that I can hear) or some quick video movement that I can see (you’ll need to see or hear this on both clips). Then I will place a ‘marker’ on each clip where the action is. Then line up the markers. Sometimes it’s still off by a couple frames so you may still need to slide the clips forward or back a few frames. But it’s a lot easier than just searching for the sync without it.
Good Luck,

Thanks for the hint. I’ve also just realized Final Cut can automatically mark all audio peaks in a track.
I’ll definitely start using a clapperboard… -
You could also invest in Pluraleyes® which will sync everything up for you in the FCP timeline. It’s very accurate – and fast.
