What you can do

Two ways to reinvent a video

  • Echo Mimic

    Your character picks up the choreography, gestures and rhythm of the reference video.

  • Echo Swap

    Film yourself as usual, then replace the car, the outfit or the scenery. You, your gestures and the camera stay the same.

  • Reference images

    Show what should appear: cite your images as @Image1, @Image2 in the instruction.

  • Several models to choose from

    Kling Motion Control, Kling O3 and other models, depending on length, quality and budget.

Who it’s for

For videos that move

  • Trends and dances

    Jump on the latest trend with your character or mascot.

  • Product demos

    Keep your footage and change the product, the color or the setting.

  • Clips and storytelling

    Give your character precise acting, taken from a real performance.
