  Grouping clips to main camera

  Posted by Holly Buechel on May 30, 2018 at 2:47 pm

  Hi all,
  I have a two-camera shoot and the source timecodes do not match. The A cam ran for the entire action and the B cam was start/stopped many times. I’d like to group the B camera to my main A camera so I can multicam edit my sequence. Is there a way to change the timecode on the B cam so I can sync them or another way I can group them? The audio is pretty terrible and it didn’t sync when I tried that.
  For now, I have a sequence with the A cam on Track V1 and manually synced the B cam to Track V2. Can I use any of this work to help me group them?

  You need to make a “sync map” that builds the angles on a timeline, and then you make groups from that.

  If the B cam was in ‘free run’ timecode then you can ‘auto sequence ‘ those clips to help build your sync map.

  Or copy start to aux1 TC, work out offset between cameras then increment/decrement timecode?

  If B cam was ‘Rec run’ TC then maybe the file creation time will get you close.

  Once sync map is built check out ‘Group it for me’

  Here’s an update:
  So I put Auxiliary Timecode in the Auxiliary TC1 column I added for Cam B that matched the place it synced up for Cam A. I put the in point at the beginning of each clip. I also added Auxiliary TC for Cam A in the column (because it didn’t do it without information in that field).
  I highlighted all of my clips and selected Multigroup with Auxiliary TC1 for Sync Clips Using and it gave me a MultiGroup and a group for each Cam B clip I was syncing to Cam A. The weird thing is, the Multigroup has Cam A repeat everytime there is a Cam B. So my Cam A clip is 17 minutes long and the MultiGroup is 1hr 42min because I have 6 Cam B clips. And I have 6 groups that are 17 minutes long and each group only synced one of the Cam A clips.
  I think I’m close, but can I get one Group that has my Cam A clip as one camera and Cam B clips as another camera?
