Multicam Sync Planner
Line up several angles on one clap: see each angle's trim, the window every camera covers, and which angle limits each end.
Enter, for each camera, the recorded clip in and out timecodes and the timecode of the shared sync event (a clap, flash or beep) inside that clip. Sequence zero is that event: every angle's mark is aligned there, so an angle's head trim is the footage before its mark and its tail trim is the footage after it. The shared window runs from the latest angle start to the earliest angle end relative to the mark; the camera that opens latest limits the head and the camera that closes soonest limits the tail, and the length between them is the multicam section you can cut without a jump. Drop-frame timecodes skip the frame numbers that make 29.97 and 59.94 count like 30 and 60; seconds are shown from the exact frame count at 29.97, 59.94 or 23.976, so they run very slightly longer than the timecode labels. Timecode labels are not checked against camera clocks, so verify the marks on a slate or waveform before cutting.
