After creating a multicam clip, can I change or add clips to include in the multicam clip?
You can open a multicam clip in the timeline and change, add, or delete the timeline used there. Unlike normal timelines, multicam clips are not displayed on the timeline when double-clicked. Right-click on a multicam clip and select "Open in Timeline" to open it in the timeline.
It can be operated in the same way as a normal timeline, but the name of the track is changed from video and audio to "Angle".
