# What do the earlier AI in-betweening papers (AnimeInterp 2021, AnimeInbet 2023) and AniDoc (2024) claim about inputs, failure modes and data, and what licences do their code, weights and datasets carry?

Abstract- and README-level only (full papers not read for storage reasons). AnimeInterp: raster-frame interpolation of one in-between from two frames, framed around textureless flat regions and large non-linear motion, with the ATD-12K triplet dataset. AnimeInbet: vector/line-graph inbetweening of black-and-white line drawings, because raster warping blurs lines; ML240 dataset of 244 sequences; Chamfer distance code. AniDoc: video-diffusion colourisation of sketch sequences, with in-betweening from start and end sketches. Terms: AnimeInterp code MIT by README only; AnimeInbet dataset CC BY-NC-SA 4.0 and code non-commercial; weights and AnimeInterp data links carry no terms in the READMEs.
