Audio-Driven Character Swap Video

This is an audio-driven character-replacement video application based on LTX 2.3.

Upload a character reference image, a reference motion video, and a driving audio clip. The application will make the reference character perform according to the motion video while preserving the original motion rhythm and camera movement as much as possible, and output the final video combined with the audio length. It is best suited for achieving the effect where "the reference character moves along with the motion video, with the entire duration and rhythm driven by the audio."

Recommended usage:

• For the character reference image, try to choose a picture with a single subject, a clear front face, and a clean background.
• For the reference motion video, try to choose a clip with a single subject, clear movements, minimal occlusion, and a relatively stable camera.
• For the driving audio, try to choose audio with clear vocals and a moderate duration.
• It is more suitable for shots with "character consistency + motion following + audio synchronization," and not suitable for complex multi-person scenes.
• To make the results more stable, you can emphasize "consistent subject, coherent motion, no extra characters, no sudden scene changes, stable camera."

Recommended input example:
The character in the reference image performs naturally following the reference motion video, coordinated with the rhythm of the driving audio, coherent motion, consistent subject, stable camera, clear details, natural lighting and shadows, no redundant characters.
