SCAIL AI motion transfer — SCAIL 2, up to 2 minutes, sound kept

SCAIL stands for Studio-grade Character Animation via In-context Learning. The name comes from the research paper 'SCAIL: Towards Studio-Grade Character Animation via In-Context Learning of 3D-Consistent Pose Representations', accepted to the CVPR 2026 Findings track, whose authors released the model code and weights on GitHub under zai-org.

SCAIL comes from zai-org, which open-sourced the SCAIL-Preview model, a 14B diffusion transformer, together with its pose extraction tools in December 2025 under the Apache 2.0 licence. On Kenerate AI, SCAIL 2 and SCAIL appear under WaveSpeed, the provider that serves them to the Motion Transfer tool.

Yes. When you open Kenerate AI's Motion Transfer tool, SCAIL 2 is selected, and the 'Street dance' starter example uses it. It is the default because it covers the most cases at once: animate or replace modes, clips up to 2 minutes, 480p or 720p, and the clip's sound kept in the result.

SCAIL 2 does: the driving clip's audio comes through in the result, so a dance stays on the beat and a talking clip keeps its speech. The first SCAIL engine returns silent video. Other engines that keep sound are Kling 3.0 and Kenerate Motion with a switch, LTX-2 Control and DreamActor v2.

Animate character moves the character in your image on your image's own background, following the clip's motion. Replace person keeps the clip's scene, camera and timing and swaps the person in it for your character. Use Animate for a clean character shot, and Replace when the original setting is the point.

SCAIL 2 uses the first 2 minutes and trims the rest; the job isn't refused. Since you pay per second of clip, it's worth trimming to the part you need before uploading. If a job fails for any reason, its credits are refunded automatically, so a test run costs nothing when it doesn't work.

Only with that person's permission. Use your own photos, characters you created, or people who agreed to it — never celebrities or strangers. SCAIL's Replace mode makes convincing swaps, so label the result as AI-made when you share it, and never use it to put someone into a scene they would object to.
