I’m editing a surgical video with 5 cameras. I have the following angles:
1. Master Wide shot
2. Close Up Cam
3. Overhead Cam
4. GoPro mounted on surgeon’s head
5. Live X-ray camera
I have an audio clap of hands to sync everything, but the issue is the X-ray cam was a very late addition to the shoot and had to stop periodically. So that one will not synced to the other cams. Do you have any advice on the best way to sync this? Do I just sync everything else then drop in the rest of the X-cam in the angle editor?

What method are you using to sync the angles (cameras) when you create the multicam clip? If you have audio on all 5 cameras, including the X-ray camera, try creating a multicam clip by synchronizing using audio. FCP is usually very good at doing this, and you may be surprised that camera 5 sync’d with the other 4, leaving gaps where you had to stop that camera.

You can try the sync with all angles; it might work for the stop/stop camera 5. If only some of the clips from that camera sync, you can open the multicam, select the non-sync’d clip from camera 5, then at left of that track click the drop down menu and pick “sync selection to monitoring angle”. It will try to re-sync only that one clip within the multicam. Repeat for any mis-synced clips. For monitoring angle pick the one with best audio, or the audio which sounds closest to camera 5 audio.
In the future, a possible way to avoid this is setting all cameras to “free run timecode”, assuming that is possible, them jam-syncing them or zeroing the timecode simultaneously. I think even some action cams permit this but you’d have to investigate. That allows stop/start shooting and FCP can sync based on timecode.
The procedure is shown below by Dave Dugdale on Sony Alpha cameras using an IR remote, but you can do it without the IR remote by just hitting a “zero timecode” menu on all cameras simultaneously. On a verbal “3…2…1…mark” command, three people could zero five cameras within about 1/8th of a sec.

I’m using the audio to sync all 5 cameras. But the problem is that during the shoot, the GoPro needed a new battery, and later on, the overhead cam also needed a new battery. So all of the other 4 angles run for 25 minutes, but the GoPro stopped at around 10 minutes in. It took some thime for the crew to notice that the GoPro stopped and then start it again. I’d like to just add the next GoPro clip to the angle editor and sync it with the other cameras, but I can’t figure out how to do that. Thoughts?

In the angle editor, click on down arrow next to the angle name at left of the timeline and select “Add Angle”, then drag the new clip from the Event Browser to the new lane on the timeline.
If a clip is synced incorrectly (or not synced) you can selectively sync or re-sync that one clip within the multicam. In the Angle Editor, click down arrow next to the angle name for the master audio you wish to sync to, and select “Set Monitoring Angle”. Then select the clip which is synced wrong or not synced, and on that lane’s name select the down arrow and pick “Sync Selection to Monitoring Angle”. Only that one clip will be re-synced.
