Line|Cut
AAF → cut detection → AAF
Finds the cuts in a line cut and writes them into a copy of the sequence's AAF, as edits on V1. Every other track comes back exactly as Avid wrote it.

The problem
The director cut the show live. You have the recording and the cameras, but no list of the switches, so you rebuild every cut by eye.
How it works

Export

02 · in Line|Cut
Find cuts
One scan finds the shot changes. Then look over the cuts it isn't sure of.

Cuts to check
The cuts it isn't sure of, six at a time. Click the real ones, double-click any you're not sure of for Review. The rest go, like the two flashes inside one shot here. V1 follows.

Move a cut
This one was found two frames late, on a flash. Click the frame before it, a frame at a time, to move it to the real cut; V1's edit moves with it.

Switch cameras
On a multicam line cut, Line|Cut names each shot's camera. Click a shot to see the mixdown beside every camera: keep its pick, or pick another.

Questions
Does it need my switcher, or a log from it?
No. It works from the recorded line cut, so any switcher, and shows that wrapped weeks ago.
What if it misses a cut, or finds one that isn't?
The cuts it isn't sure of come to you six at a time. Click the real ones; the rest go. V1 follows. Like any detection, it can miss a cut or mark one that isn't there, so watch the result before it goes anywhere.
Which Media Composer?
Tested with Avid Media Composer 2025.12: multicam at 29.97 fps and markers at 23.976.
Does anything leave my Mac?
Your media and projects never do. Line|Cut checks for updates (sending only its name and version), and sends a problem report only when you choose to. Studio mode turns these off.
