Motion In-Betweening Dataset
Dataset Description
This dataset contains character animation sequences from production. It is used for training and evaluating the motion in-betweening method presented in:
https://arxiv.org/abs/2605.02742
Raël et al., "Adaptive Interpolation-Synthesis for Motion In-Betweening on Keyframe-Based Animation", SIGGRAPH 2026 Conference Papers (2026)
Dataset Summary
The dataset provides character animation at 24 fps for a single production rig, with each frame represented as a D=596-dimensional vector of rig controller values. It is split into two subsets:
in_house_dataset:8.5 hours of internal production sequences, split 95% for training and 5% for held-out evaluation (test_held_out_algorithmicandtest_held_out_randomsplits).prod_test_dataset:5 minutes of production data with ground-truth blocking keyposes, used for thetest_productionevaluation split.
For each subset, the dataset provides the processed per-frame controller-value sequences (vectorized_controller_values/) along with the corresponding block keypose annotations (vectorized_block_keyframes/). For in_house_dataset, the block keyposes are determined by the Domain-Based Algorithm; for prod_test_dataset, they are ground-truth animator block keyposes.
