A lot of clips have more than one person in them, and you do not always want to change all of them. You have the choice, and it is more flexible than most tools allow.
The simplest case: put one new face on everyone in the clip. But you can also swap a single person and leave the rest of the group exactly as they were — handy when you only want to appear in one seat of a crowded scene.
You can go further and map different source faces onto different people in the same shot — you become one character and a friend becomes another, in a single clip. That is what turns a two-person scene into something you can both be in.
When you upload, the page scans the clip and shows the faces it found, so you pick which to replace and with which photo. If the scan is slow or cannot find a face, you can skip it and every face is swapped instead — often what you wanted anyway.
Real clips are messy: a hand near the cheek, a mug in front of the mouth. The swap keeps things that pass in front of the face rather than painting over them, so the new face sits behind them the way the real one did.
Your face is personal. Exactly what we store, for how long, and the 24-hour rule that deletes everything you upload and everything you make.
