Temporal Motion Completion · HumanML3D

Unified public leaderboard for temporal-conditioned human motion generation on the HumanML3D official test split. The page exposes two protocols:

• Temporal Control: prediction, motion in-betweening, and adaptive sparse keyframe control, with text-on and text-off settings where applicable.
• TP2M Prefix: caption-guided continuation from 1, 5, or 9 observed motion frames, evaluated in MotionStreamer-272 space.

Every setting includes a visible GT reference row. GT semantic metrics are reused from the matching Text-to-Motion · HumanML3D benchmark rather than recomputed. For Temporal Control, condition error and failure rates are zero by identity, and foot skating is measured with one deterministic pass over the 4,012 temporal test clips. GT is excluded from ranks, best/second highlighting, and chart normalization.

The quantitative table includes all eight 4,012-case ProjFlow runs. ProjFlow's native Motius artifact and task APIs are documented in its Model Card. Its all-case mesh pack has not been added to the qualitative explorer, so the viewer does not present a partial or mixed-protocol ProjFlow row.

The page supports task filtering, method search, sortable metrics, bar and radar comparisons, and protocol-specific details. Ordered multi-prompt composition is maintained separately on the Sequential Text-to-Motion · BABEL benchmark.

Temporal Control also provides six all-case Three.js explorers. Each contains all 4,012 official cases and the aligned GT, CondMDI, FlowMDM, KIMODO, MotionLab, and MotionCanvas motions as synchronized neutral SMPL meshes rather than joint-only skeletons. The selected setting can be switched without loading unrelated motion chunks; large assets live in the public ZeyuLing/Motius-Leaderboard-Cases dataset.

The static Space is defined by:

• index.html: page structure and responsive styling.
• leaderboard.js: interaction, ranking, and chart logic.
• temporal_control_results.json: structured Temporal Control result snapshot.
• cases/: one lightweight manifest and viewer per Temporal Control setting.
