Multicam source sequence help/tutorial
Experienced multicam editors: I think I'm asking a lot, but do let me know - I realize it might be better for me to work with a tutor or consultant more directly, but I thought I should start here. Any tips for solid online tutorials are also welcome.
I have some specific tech aspects that are complicating my understanding of how to properly set up a multicam source sequence and project workflow. (I have a production within which I'm creating 3-camera episodic projects. I'm not inexperienced, but I'm trying to do this the right way, having had some nightmare dependency issues from poor nesting practices, and the variable audio channel count was causing invisible-to-me problems.) My intent is to get a sensible, repeatable clean flow for future episodes, and trying to correct existing projects as best I can rather than rebuild.
Two identical cameras (GH6) =5.8k 10b 4:3, 3rd camera (G7) is 4k 8b 16:9. (All Long GOP; proxies created on import) Deliverable is 1080/24p, Rec709. Cameras are static. The two open-gate cameras have room to crop top and bottom to accomodate 16:9.
Two cameras have four audio tracks, the third has a single stereo track. (This variable has created confusion in the past) All cam audio is scratch for sync, but really only need one channel to do so.
Before video editing I mix and master the externally recorded 2-person interview dialogue to a stereo wav, which becomes my only dialog track.
1) How and when do i deal with the audio channel count mismatch? Seems like I should do this before creating any sequences. I have experimented with modifying audio channels down to mono, and I can "create sequence from clip" that reads as mono, but I can't drag an additional clip into that sequence. Something isn't quite right.
2) how and when do I set my open gate clips to a 16:9 frame? After I've made my camera angle cuts, I will do some reframing and zooming, but would prefer to start with a non-pillar boxed image already. Is this possible?
3) How, when, and where do I apply the lumetri adjustments? this project requires little to no grading per se, but I do need to color correct, apply slight curve adjustments, add a vignette and match cameras reasonably well. The lighting and exposure does not change over time, so doing this once per angle upfront rather than per individual cut is definitely preferred. I do want the flexibility to make global-per-clip adjustments even after the camera angle cuts have been made.
4) How, when, and where do I actually create the multicam source sequence, given these above concerns, that gives me this flexibility?
5) Details for context: in the final assembled sequence, the 30-ish minute multicam interview sequence follows an animated logo with SFX and music, a short teaser excerpt somehow lifted from the multicam interview, a one minute, one camera introduction and followed by a closing MOGRT credit roll.
6) M1 Max studio, 64GB RAM, Sequoia 15.7.3, Premiere 25.6.4
Thanks for reading this far, and I appreciate any observations or questions you might have.
