Motion Transfer
Motion Transfer takes a source video for movement and combines it with a character reference image for appearance. The mode selector decides which part survives the combination.
#Modes
#Motion
Apply the source video's motion to your character reference. The output keeps the character and scene from your reference image, and moves them following the source video's timing and trajectory.
Use when:
- You have a character (yours or a generated one) and want them to dance, walk, or perform.
- You found a great motion clip and want a new subject to do the same thing in a different scene.
#Replace
Keep the source video's motion and scene, but swap the subject with your character reference. The environment, camera moves, and choreography stay; the person (or character) in the frame changes.
Use when:
- You want to put someone into an existing performance / scene.
- You need consistent motion across multiple subjects in the same setting.
#How to use it
- Switch Create mode to Video.
- Open the Motion Transfer panel in the sidebar.
- Add a character reference image — the look you want preserved.
- Add a source video — the motion you want transferred.
- Pick a mode — Motion or Replace.
- Write a prompt describing the result (optional but recommended for Replace).
- Pick a video model — Wan 2.2 and LTX-2.3 both support motion transfer workflows.
- Generate.
Matching the framing between the reference image and source video — same shot size, same approximate camera angle — leads to noticeably better results. A close-up portrait paired with a wide full-body motion clip will produce more artifacts than two matched framings.
#Tips
- Keep source clips short. Motion transfer scales with frame count; start with 2–4 seconds and extend the result with Clip Mixer if you need more.
- Lock the seed when you find a good run. Motion transfer is sensitive to random initialization; the seed control matters more than for ordinary T2V.
- Use Replace for scene continuity. If you need the same subject across multiple clips in the same environment, Replace each clip from the same reference image — you'll get tighter consistency than re-generating the scene from scratch each time.
- Match aspect ratios. Mismatched aspect between reference and source produces letterboxing or stretched motion. Crop the reference to match.
