ToonComposer (arXiv v1, Aug 2025) merges in-betweening and colouring into one step on a Wan2.1 video model: a colour reference frame plus one or more keyframe sketches (any frame position) and optional region masks produce the clip. Evaluation: synthetic benchmark from cartoon films used with permission, PKBench (30 scenes, start/end sketches drawn by professional artists) and a 47-person preference study (70.99% aesthetic, 68.58% motion for ToonComposer). Stated problems: baselines distort faces and are sensitive to bold line styles; blank sketch regions render flat unless region masks are used; compute cost (README: 61 frames at 480p needs ~57 GB VRAM). Licence statement is MIT including weights.
