Replace Anyone in Any Video · Tyndall AI
Upload a reference video and replace the characters. Get the same clip back with your people doing every move — original sound included.
Character photos
One person per photo, up to six
How it works
Step 1
Upload the reference video
Any clip with people in it. We use the first 30 seconds, keep the framing, and put the original sound back on the result.
Step 2
Upload your characters
One photo per person, up to six. Face forward, good light. Waist-up or full body carries clothes better than a tight crop.
Step 3
Say who replaces whom (optional)
Leave it empty and photo 1 replaces the most prominent person, photo 2 the next, and so on. Or write a short casting note.
Step 4
Generate
You get one continuous video back in the same length as the reference (up to 30 seconds), with the original audio.
What you get
Whole-person swap
Face, hair, build and clothes come from each photo — not a blend with the original performers.
Same moves, same beat
Gestures, timing, camera work and scene stay with the reference clip.
Up to six people
Cast one to six photos in a single run. Anyone without a photo stays as they are.
Original sound
The song or voices from your clip are remuxed under the finished video.
Face swap video online: replace anyone in any clip
You have the clip — the dance, the trend, the friend video. Now put someone else in it.
Upload a video and a photo of each person who should be in it. You get the same clip back, up to 30 seconds, with your people doing every move, every turn and every expression, with the original sound.
It is more than a face swap: the whole person changes. Faces, hair, build and clothes come from the photos. Everything else stays.
Tips for a better result
One person per photo
Crop out anyone else before uploading.
Show the outfit
A full-body or waist-up photo tells the model what the clothes look like.
Clean reference footage
People fully in frame, clearly lit, not too many at once.
Trim first if needed
Only the first 30 seconds are used — cut longer videos to the part you want.
Keep casting short
“Second photo replaces the woman on the right” does more than a paragraph.
Run it twice
Each run comes out a little different. Keep the one where the hands look right.
FAQ
How long can the video be?
Up to 30 seconds. A longer upload is cut to its first 30 seconds, so trim to the part you want before uploading.
Can I swap more than one person?
Yes. Upload one photo per person, up to six, and say which photo replaces whom. Anyone without a photo stays as they are.
Is it just the face?
No. The whole person is replaced: face, hair, skin, body shape and clothes all come from the photo. Moves, expressions and the scene come from the video.
Does it keep the sound?
Yes. The original audio of your clip goes back under the finished video. A silent reference gives a silent result.
Is Replace Anyone free?
You get daily free credits to try. Sign in is required so credits can be applied.
Can I use someone else’s face?
Only with their permission. Celebrities and public figures may be refused by safety filters. Use photos of people who agreed to be in your video.
