How to extract multiple camera's from one source file containing multiple angles side by side?

Report · Aug 20, 2024

I'm new and might not use the correct terminology, which also makes searching for this difficult in the community; apologies.

I have one source file (mp4) that has a huge resolution (5760x4040 I think). Within that file are multiple camera angles (5) and other screen captures (3) side by side. See my sketch attached to this post/ below. Important to realize is that the one file has thus all camera images in “one track”.

(Scetch - all this is one frame in one file having the camera's side by side.)

So my question, what is the best way to mark the “camera’s” in that file so I can use them with multicamera editing? So how to I mark “area’s” in the one file as separate camera’s? How'd you handle this?

Additional question: if I do end up needing to extract them to separate sequences (and later add them together to do a multicamera edit); is there a way to save the “stencil”? So that I can easily extract the sequences without memorizing the x,y-coordinates to crop/ pan each camera on each new file.

Thanks for any tips and pointers to the correct solution and or terminology :).

Here’s how I would do it:

Duplicate the clip in the Project panel so you have 8 copies.
Select all clips and choose Clip > Create Multi-camera Source Sequence.
Set the Synchronize Point to In Point.
Set the Audio Sequence Settings to Camera 1. This will create a multi-camera source sequence where all 8 angles are the same clip.
Right-click the multi-camera source sequence in the project and choose Open In Timeline.
Select each clip in the Timeline and adjust the scale/position for each angle.
