| # 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: |
|

|
|
| ## 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_algorithmic` and `test_held_out_random` splits). |
| - **`prod_test_dataset:`** 5 minutes of production data with ground-truth blocking keyposes, used for the `test_production` evaluation 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. |
