wan2.2-animate-move vs animate-mix, and Sume's motion transfer

The two Wan 2.2 models solve opposite problems. wan2.2-animate-move takes a static character image and moves it with the motion of a reference video, keeping the background unchanged. wan2.2-animate-mix takes a video and replaces the character in it with one from a source image. Sume has a single motion-transfer row, Genjutsu, and it matches the move case only.

Alibaba's side is from its Model Studio video generation page, read 2026-10-01. Sume's side is from the Video Router docs.

What is the difference between move and mix?

Both are listed for 720P output and 2-30 s. Alibaba's page describes both as having a pro mode (wan-pro) and a standard mode (wan-std); the page gives the pro mode as closer to live-action footage. The page does not list a price in the section read here, so none is claimed.

Which one does Sume's motion transfer match?

The move case. In the Video Router catalog the Genjutsu row is described as Motion Transfer only: a video_url plus 1-8 reference_image_urls, with no text-only generation. The video supplies the motion and the images supply the character. Sume's docs do not describe a character-replacement mode for it, so treat animate-mix as having no equivalent there.

If the goal is to keep a person's performance and swap who appears, that is the mix task. Sume's other video_url row, Gemini Omni Flash 1.1, is an edit row driven by a text prompt; see edit a video with a prompt for what it accepts.

What are Sume's limits for this row?

Per the Video Router docs, the row serves 480p and 720p, 4-30 s, and the duration is the input video's length, rounded up. It sends no aspect_ratio, generate_audio, bitrate_mode or audio references. It is also listed only when its provider is configured, so check GET /v1/video-router/models before building on it.

Alibaba's 2 s minimum is lower than Sume's 4 s, so a 2-3 s motion clip that works there needs to be 4 s or longer here. Inspect the source clip first.

What should I do?

Pick by task. To animate a still with a reference performance, send the clip and the character images to the Genjutsu row. To swap a character inside existing footage, use a tool built for replacement; Sume's catalog does not list one. Read capabilities from the catalog rather than assuming an envelope.
