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.
