Swap Four Faces in One Pass, Not Four Separate Edits
With a single face tool, a four person clip means four exports and a stitching job in an editor, and every pass risks a slightly different color or timing. A multiple face video swap runs all four at once from one upload. Group dance trends, friend skits, party recaps, and reunion clips all come back as one finished file, usually in a couple of minutes.
Pick Who Changes and Who Stays As Filmed
You decide face by face. Replace all four detected people, or leave some exactly as shot. This is the practical option for a wedding video where the couple stays original and the guests get new faces, or an ensemble fan edit where only certain characters need changing. Anyone you skip is untouched in the output, and if your clip has more than four faces, the extras stay as filmed rather than throwing an error.
Give Each Person a Different Face
Four detected people can become four different people, not one face copied four times. A video multi face swap assigns your source photos slot by slot, so a family greeting can cast every member as a different character, and a four character scene can be recast with four different friends. Nobody in the frame shares a face unless you deliberately assign the same photo twice.
Recast a Whole Group Scene at Once
Some footage only works if everyone in frame changes together. Team intro reels, offsite recap videos, group reaction clips, and ad variants with several people on camera all fall apart when one face is swapped and the rest are strangers. Swapping the full group in one run keeps the scene coherent, and it lets you test a second cast on the same footage without booking a reshoot.
