What preprocessing limits and licence apply to Wan-Animate when an actor video drives a character image?

Problem: the open Wan-Animate model needs pose and face streams extracted from the actor video, and mismatches cause artifacts. Conditions: Wan2.2 repo; animation mode (character mimics actor) or replacement mode (character replaces the person in the video). Method: preprocessing outputs src_pose.mp4 and src_face.mp4, plus src_bg.mp4 and src_mask.mp4 in replacement mode; the paper abstract says body motion is replicated with skeleton signals and expressions with implicit facial features. In animation mode, enable retargeting when body proportions differ, and check the preprocessing results before generation. In replacement mode retargeting is off by default. Failure modes: significant body-proportion mismatch can cause deformation; mask extraction targets single-person videos and can fail with several people; a lower fps setting can cause choppiness. Rights: weights are Apache 2.0, with a use clause barring content that violates laws or harms individuals. Limitations: not run by me. Version/date: README and guide fetched at stamp; arXiv v1 dated 17 Sep 2025. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Extends the existing run-through; adds only limits and licence wording. No consent mechanism is documented by the repo. No outputs inspected. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
