Act-Two

Act-Two animates a character from a 3–30 second performance video. Supply either a character image or character video with a clearly visible face; the reference performance drives the result, while body control and expression intensity adjust how motion and expression are transferred.

How to use this model

  1. 1

    Choose one character source—an image or a video—with a clearly visible face.

  2. 2

    Upload the performance video and select a segment between 3 and 30 seconds.

  3. 3

    Enable body control when the reference body movement should guide the character, and set expression intensity from 1 to 5.

  4. 4

    Choose the output ratio and review face visibility and framing before generation.

Act-Two

Use Act-Two to transfer a visible-face performance to one character source. The selected reference segment supplies the performance timing; body control and expression intensity determine how strongly its movement and facial expression guide the result.
