[Greg Ball] “…editing a series of 90-minute presentations with 3 cameras….I’m trying to synchronize the angles, and it’s taking forever. Is this normal? Any way to speed this up?”

From Apple KB article PH12659 “Final Cut Pro X: Create multicam clips in the browser”:

https://support.apple.com/kb/PH12659?locale=en_US&viewlocale=en_US

“Some audio recordings are not suited for use with this feature. Selecting this option may result in long processing times”

To expedite this the article suggests:

“First Marker on the Angle: Final Cut Pro uses the first marker in each angle as the sync point….you can use the first marker to define a region that can be fine-tuned with the “Use audio for synchronization” option (described above). In other words, you don’t need to place the marker exactly—just close enough so that the automatic audio sync feature can sync the angles the rest of the way.”

[Joe Marler] “To expedite this…”

Exactly what I was about to suggest, too. Had no idea that that was in the manual. Good to know. ????

Alternatively you can also make a selection of the first minute or so of each clip, make a multicam just from THEM, then simply extend them to full length in the Angle Viewer once the MC is created.

[Greg Ball] “90-minute presentations with 3 cameras. 2 angles are the presenter wide and tight shots, and the third is an Atmos recording of the PowerPoint slides. All video is 1920 X 1080P 29.97 frames per second.

I’m trying to synchronize the angles, and it’s taking forever. Is this normal? Any way to speed this up?”

Besides the previous comments you can also use PluralEyes which has better and faster sync algorithms than FCPX: https://www.redgiant.com/products/shooter-pluraleyes/

Another option is use Tentacle sync devices. My doc team uses these frequently and they work very well. I just synced a 3-hr-long six-camera 4k shoot using Tentacle and it took a few seconds, despite most of the cameras shooting stop/start: https://tentaclesync.com

BTW: the issue being, that if you use audio sync ONLY, then you’re telling Final Cut to “listen” to each clip in its entirety and figure out how and where they sync up. Obviously not a good idea when the clips are that long. As the manual states, by setting even just rough markers in each clip around the same spot tells FC to “listen around this area”, not the entire clip.

Pretty darn clever if you ask me.

In summary: For long takes, like events, presentations and performances, using a sync point or markers from something like a clapperboard will always be faster. If you have loads of media to sync which has not clear sync point then try out the Red Giant Plug-in:
