| | `motionfix_val.pth.tar` | 263046195 | `6ec5b2da91705c32cb495be3b931d2c42136fcbcf5763eadad365052307116e7` | Validation split package, 330 triplets. | |
| | `motionfix_test.pth.tar` | 805265131 | `cd2c59a69f0854f5b3cffeebc026fd6df2f63b75e813f6a6151cafa96b76eaea` | Test split package, 1,013 triplets. | |
| | `splits.json` | 94284 | `1f91f945b76c85b2780fd9dbdce32bde1f14988a06ceecf16cb2eb4e02d0de45` | Local train/val/test split list. Contains one train id, 006722, that is absent from the full package and annotation JSON. | |
| | `amt_motionfix_latest.json` | 6289990 | `8d999be2bffe086cfe2816aefdba944782dc3534e1c45e3fc4dcd5ac8755d203` | MotionFix metadata/annotation JSON, 6,730 entries. | |
|
|
| ## Data Format |
|
|
| The `.pth.tar` files are Python pickle files containing dictionaries keyed by MotionFix sample id. Each item contains: |
|
|
| - `text`: edit instruction. |
| - `motion_source`: source motion dictionary. |
| - `motion_target`: target motion dictionary. |
|
|
| Each motion dictionary contains `rots` `[T, 66]`, `trans` `[T, 3]`, `joint_positions` `[T, 22, 3]`, and `timestamp`. The observed validation and test packages use 120-frame clips. |
|
|
| ## Split Note |
|
|
| `motionfix.pth.tar` contains the full 6,730-triplet release. The local `splits.json` contains 6,731 unique ids (`train=5388`, `val=330`, `test=1013`), but train id `006722` is absent from both the full package and `amt_motionfix_latest.json`. Consumers should filter missing ids when using `splits.json`. |
