AI Replace: Swap Characters, Outfits and Locations in Video

    AI Replace changes one thing in a video you already have: the character, their outfit, an object or the whole location, and keeps everything else. The original movement, facial expressions, script and sound stay as they were, so one shoot turns into several versions without filming the scene again.

    Key features

    • Replace a character — Swap the person in the clip while their movements and actions stay the same.
    • Change outfit, object or location — Turn casual clothes into a suit, an office into a café, day into night.
    • Motion and sound stay — The original timing, facial expressions and audio carry over to the new version.
    • Guided by a photo — Upload a picture of the outfit, place or character you want, instead of describing it in words.

    Best for

    FAQ

    What can AI Replace change in a video?

    The character, their outfit, objects and the location around them. One generation focuses on one change, so you can build several versions of the same scene.

    Does the original audio stay?

    Yes. AI Replace keeps the original sound, timing and facial expressions, and changes only what you chose to replace.

    Do I need to describe the new look in words?

    Not necessarily. Upload a photo of the outfit, place or character you want, and AI Replace uses it as the reference.

    How much does AI Replace cost?

    It depends on the length of your video. The app shows the exact price in credits before you start the generation.
