Multicam Synchronization is so slow
on Feb 10, 2015 at 5:01:11 am

I don't know if its the length, or the number of video & audio channels? I have a new Thunderbolt 2 G-Tech drive going into a Macbook Pro 2.5 Ghz with 16gm of ram and usually things run pretty quickly for me and FCPX. This is my first heavy lifting Multicam sequence I am setting up and I renamed all my clips according to each camera, take and scene. Made sure it was all Scene 1 with each of the 4 video and 4 audio channels, and it is dragging on forever. It's been almost 3 hours so far and I'm not sure what to do. I did one round and got the beach ball, this round is going fine but it is just slowly crawling.

Anything I can do to speed this up? I can'r really separate this into chunks, but I guess I could try? If I didn't transcode PROXIES, how would I go about using Proxies instead of the masters to maybe speed things up?

I'm fairly new to this so any help would be great!

You have to transcode in order to use proxies no way around that. How long are the clips and what codec? If they are hour+ H.264s, expect a long wait on that hardware.

Hi and thanks!

It was about 15 takes of 4 cameras + plus 3 audio. In all, about 30 minutes per video /audio. It hasn't gone to the spinning ball, so I assume it is still going?

The original footage were Panasonic AVC, but I've transcoded everything to Optimal ProRes. I'm thinking I should do Proxies to help speed things up. That being said, I've not used Proxies yet, is there anything I need to do aside from Transcoding the footage to Proxies? When I go to sync everything up via Multicam, will it automatically go to the Proxies to sync up or do I need to tell it to use the Proxies?

Thanks for the help.

PluralEyes 3 by Red Giant is a much faster way of creating and organizing multicam clips for Final Cut Pro X. I work with multicam projects consistently and for me, using PluralEyes 3 is the only way to go.

Check out the demo from Red Giant here:

and you're doing all 15 takes at once? Yes this will take a long time.

Yeah, the show was improvised so I don't know which moments will be the best, so I need to bring everything in and handle it all. I know, crazy, but I think its how I have to deal with it.

I think I'm gonna give Plural Eyes a try to see if it handles it faster than FCPX does. I'll give FCPX tonight to try to get this right, but it seems like Plural Eyes is far more robust and as a niche product, probably handles this past better.

What are your multicam settings?

So I was going through the footage and realized 3 of the 4 cameras are 29.97, which is what my setting is for the timeline (720p, 29.97), but one of the cameras was shot at 720p, 23.98. When I removed that camera, it has been moving much quicker, for obvious reasons. So now I'm trying to figure out if I should go to the camera that shot 23.98 and convert it to 29.97 outside of FCPX in some conversion software? Or how should I handle, I still need that camera badly, so I need to figure out a workflow to get all that footage (3 days worth) into a format that will play nice with my 29.97 footage.

Any thoughts? Any good third party software to convert from 23.98 to 29.97?

Thanks,
Daniel

The time savings in using Plural Eyes over FCPX syncing will pay for itself in under two weeks. I have to sync two hour timelines all the time. Not even worth trying in FCPX. I only use the NLE sync for sequences under a 10 minutes. If you have long takes, it may be ok. But stop/start run and gun over a long period of time....fuhghetaboutit.

IMHO, definitely convert it to 29.97 outside of FCPX. Compressor will do that nicely. Be sure to turn on Frame Controls and select the highest quality for rate conversion.

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?

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.
