Multicam Synchronization is so slow

[James Culbertson]

3 hours seems like something is wrong. Shouldn’t take more than 5-10 minutes to sync at the longest for a 2 hour 2-3 camera (single clip or broken up clips). Most of the time much less. At least that is my experience. Have you set the camera angle field correctly?

Here’s how I set up the Camera Angles, based on a video I watched on it.

I didn’t think it would take that long. Also, when I did a smaller selection (1 Take), which had 3 video and 4 audio channels, they weren’t in sync, is there something I need to do to prep the files to be in sync?

Not quite sure why you’re using such complex names for your angles.

All they do in the X database is allow it to understand what to put on the same track in the Angle Editor – and what to split onto separate tracks.

All I ever use is A, B, C, D, etc.

The rest of the ascii characters are irrelevant. So why force the program mess with them?

FWIW.

I didn’t know better.

So for Camera’s I’ll use A, B, C, D and for Audio should I use X, Y, Z to sort the audio?

I’ll simplify it now.

Any other suggestions?

Try syncing the 29.97 angles only. Any better?

[Bill Davis]

Definitely try what Jeremy suggests.

One thing about the way X does Multicam is that you can use it in an ADDITIVE fashion rather than needing to sync everything all at once.

In other words, If you have 20 cameras – but only 12 of them have good sync audio. You can sync just the 12 at first. THEN go back and add the additional angles that might be more problematic. Not only that, but you can elect to sync the first batch via audio waveforms, (or timecode or whatever) but then add additional angles based on OTHER sync criteria. So if cameras 13-17 all have a shot of a particular action – you can put manual markers on that sync point and then ADD those angles to your original 12. Then take a look at the last 3 angles and perhaps find a muffled audio hit, or a physical movement that is reflected in ANY of the already synced tracks, and use that as a sync strategy to add the next three.

X is almost amazingly flexible in this way, working well beyond the simple idea of “if EVERYTHING doesn’t work, then that means nothing is working.”

Have fun.
