[Jeremy Press] “live theatre production with two cameras…I had a separate mic and, thus far, have made four sync clips — two synced to first performance audio track and two synced to the second. The performances on both nights are close, but not close enough to multicam.
Right now I’m attempting to edit by dropping scenes from the browser onto the timeline, but it’s proving to be a monster (it doesn’t help that the play is 3 1/2 hours long).”
I just spent five weeks editing a similar multcam stage act with multiple performances. It is difficult, esp. if you need to mix performances.
I suggest using multicam not sync clips. Make separate multicams for each performance. Do not drop parent clips into the timeline; those don’t have quality audio (unless each camera received the house feed).
If you need a “best of” or overview reel that’s one thing. The dilemma is if you need complete coverage. In that case you can’t just put in favorites.
Normally the preferred approach is mark/keyword the multicam clip in the browser. With FCPX you do maximum possible work in the browser. However if you need complete continuous coverage, that is different.
Yet you can’t fully sync both performances together — they are too different. I’d be tempted to lay the two multicams on top of each other in the timeline, maybe insert periodic gap clips to roughly maintain sync, then visually go through them with the angle editor enabled.
Mainly (or solely) use audio from one performance. You’ll have to make a case-by-case judgment on when you can cut to video of performance #2 and keep “good enough” sync. It might be possible to switch audio in some cases if you expand audio, overlap and feather them together. It depends on how similar/different the audio sounds.
The goal is leverage each performance as a multicam to the degree possible, and somehow blend them in the timeline. It’s not easy but it’s easier than just patching in camera clips.
If there was anyone else shooting (ie crowd reaction shots, etc) and you can get that material it would help – even if cell phone. That would allow cutaways to cover difficult cases.
