ToonCrafter (arXiv v1, May 2024; SIGGRAPH Asia 2024 journal track per README) generates intermediate frames between two cartoon images with a fine-tuned image-to-video diffusion model, optionally guided by sparse sketches. Released model: 16 frames at 512x320 from a start and end image plus text. On its own 1K cartoon test set it reports FVD 43.92 vs 98.96 for the next best (SEINE) and a 24-person study with 68.98% preference for motion quality; it does not win LPIPS (0.1733 vs 0.1702 FILM). Stated failure modes: baselines fail on dis-occlusion and non-linear motion; unadapted priors leak live-action content; compressed latents cause flicker/detail loss; the maintainers state the success rate is not guaranteed.
