Merged summary
TL;DR - Wan-Animate-2 is an end-to-end character image animation framework built on a redesigned Diffusion Transformer that consumes the driving video directly, removing intermediate motion extractors, and ships a distilled "Lite" variant that runs at real-time latency for streaming avatars and live-stream hosts.
- Motivates the design by faulting three prior paradigms: explicit motion representations (extraction errors, identity drift), implicit motion features (fine-grained dynamics lost to compression), and in-context learning (prohibitive compute).
- Feeds the driving video straight into the DiT, which the authors credit for better motion fidelity and identity preservation; adds text-driven viewpoint control that decouples output camera perspective from the driving video.
- Wan-Animate-2-Lite reaches real-time inference via a three-stage recipe: teacher-forcing pretraining with an error buffer mechanism, then Self-Forcing distillation with chunk-wise backpropagation.
- Evidence is qualitative evaluations plus user studies (no quantitative benchmark numbers given here); the Wan-Animate-2-Base weights are stated as a planned public release.
