In which I suggest a feature for Apple’s Final Cut – a way to create and edit multiclips (clips that can be switched as live between different camera angles).
Here’s another idea for a future version of Final Cut. To make multiclips a lot more flexible, imagine being able to use any (single codec) sequence as the source of the multiclip in any other sequence.
Shooting productions in order to prepare for multiclip editing is a little unforgiving. If sequences can be switched like multiclips, shows with timecode problems could be set up in sequences like this:
You can see here that cameras 1, 2 and 3 were started and stopped during the performance. Camera 4 had a sync problem, which was fixed by delaying the audio 9 frames.
Imagine if you could view this sequence as a multiclip. Instead of video layers, you would have video angles. Audio channels would move to be associated with their specific video angle:
All the angles would remain editable as tracks – you could change filter settings, clip positions and keyframes. The extra rows at the top of the display would give you the option to blade to cut between angles, choose which angle to switch to, roll to reposition cuts, add transitions to video and audio edits (but probably not ripple, slip and slide. You could make those kind of changes in the rows in the lower part of the window). You could treat the area as a preview of how the multiclip will appear if it was added to a ‘parent sequence.’
Once you are happy with the sequence, you could then add it as a multiclip to a parent sequence by holding down a modifier key as you drag to the canvas:
Once the multiclip is on the parent timeline, it would be editable in the same way as it is today.
