A ‘virtual multicam’ mode. Mainly for reality type shows but also useful for sports & entertainment shows, indeed anything with multiple sources shot contemporaneously.
How it would work:
Toggle view from current single timeline clip to show any/all clips that match that that clips shoot date & ‘multicam reference timecode’. (Audio tracks also to be available.)
Should compensate for CFPS (shoot frame rate)
On well organised productions shoot date & timecode & cfps metadata would be accurate.
In other cases shoot date could be generated from file creation date and/or manually adjusted. Timecode similarly could be calculated from file creation time, with automatic/manual offsets for cfps.
