Recast vs face swap vs green screen
Recast (BeMainStar, Viggle) replaces the person in the scene with you, so it is you doing the moves. Face swap (Reface, DuoFace) puts your face on the original person's body. Green screen (CapCut) is you, filmed for real and cut into the clip. Which one you want depends on whether you can dance the part yourself.
BeMainStar
Any 5 to 30 second clip from Photos, one selfie, up to 4 people, the same camera and sound. No watermark. A subscription is needed to start: Weekly is $4.99 with 5 Stars each week, Yearly is $89.99 with 8 Stars each month. 1 Star is 1 second of video, and Star packs of 5, 12 or 25 Stars top you up. Prices vary by country. If a video fails, your Stars come back.
Viggle AI
The broadest toolset in this list, with more than 8,000 templates and up to 5 free generations a day per its listing. The best place to start if you are not sure yet.
Reface
About 496,000 US ratings and a long track record. Strongest when you want to browse trends rather than bring your own clip. Rated 17+.
DuoFace
Its listing is short: morph faces in your videos, start for free, upgrade to Pro for longer clips and no ads. Plans on its listing are sold by seconds of video, weekly or yearly.
CapCut
Not an AI recast app, but its listing includes chroma key and background removal. If you can do the moves, film yourself against a plain wall and layer yourself in.
