Can I replace a person without changing the music?
Yes. Upload the video and add one photo for the person you want to replace. The music in that file stays the same music, on the same timing. Vocals, dialogue, and sound effects that were recorded stay too. The dance, the camera, and the cuts stay with the take. The download is 720p. You do not write a prompt, and there is no switch for a different song.
What you change, and what you keep
The photo is who appears in that person's place: face, hair, and clothes come from the picture. The song does not get a new arrangement, a new vocal, or a new start time. It is the track that was already in the file.
- The music
- The song in the file stays, unchanged, in the download.
- Vocals and dialogue
- Singing and speech that were recorded stay.
- Sound effects
- Effects that were already in the file stay.
- Music timing
- The song stays lined up with the same counts.
- The dance
- Steps stay with the take you uploaded.
- The camera
- Zoom, movement, and cuts stay.
- The person
- The one you add a photo for. Everyone else stays as filmed.
One person, or more
A solo needs one photo. If the clip has more clearly visible people, add a photo only for the ones you want to replace. Anyone without a photo stays as filmed, on the same steps, with the same song. A face that stays tiny in the background may not be listed. A scene longer than 15 seconds cannot be generated.
The song stays yours to clear
Keeping the music means the audio from your file is in the download. Genjutsu AI does not give you a new license to that music. Use a video you have the right to upload, including the song already in it. A photo of someone else needs their permission.
What it costs
Drop in mp4, mov, or webm, up to 80MB. Ten credits cover every 15 seconds. The first order is $6.90 and covers one video up to 15 seconds. After that, the Starter Pack is $9.99. The price shows before you generate. A failed generation returns its credits.
Change the person, keep the song
Sign in, drop the video, and add a photo for each person you want to replace. Finished videos stay on the account.
