00:00:00.000 --> 00:00:04.000
A clean edge can still look pasted on.

2
00:00:04.000 --> 00:00:08.000
Wrong light on the subject is the first tell.

3
00:00:08.000 --> 00:00:12.000
Cutout Match measures Lab colour on both sides.

4
00:00:12.000 --> 00:00:16.000
It moves only pixels inside the matte.

5
00:00:16.000 --> 00:00:20.000
Missing contact shadow is the second tell.

6
00:00:20.000 --> 00:00:24.000
