Abstract

Conditional human motion generation remains a fundamental challenge in computer vision and robotics. Despite significant progress, current methods are often constrained by fixed modality configurations and task-specific architectures, leaving cross-modal interactions and the scaling laws of multimodal-conditioned synthesis largely underexplored. A key bottleneck is the scarcity of large-scale modality-aligned motion data, limiting generalization across diverse control signals.

In this work, we introduce OmniHuMo, a large-scale, high-quality dataset comprising over 5,000 hours of motion and 3.2 million sequences with precisely aligned multimodal annotations (e.g., text, speech, music, and trajectory). Leveraging OmniHuMo, we propose AnyMo, a unified multimodal framework combining a Residual FSQ-based motion tokenizer with a scalable masked modeling transformer, enabling high-quality motion synthesis under arbitrary modality combinations. Extensive experiments show that AnyMo achieves high-fidelity synthesis while offering flexible control over both spatial and stylistic attributes.

Any-Modality Motion Generation

From an action description to a voice, a beat, or a path.
One framework brings diverse conditioning signals into motion.

From videos to
multimodal motion.

OmniHuMo turns diverse online videos into a corpus of 3.2 million human motion sequences, spanning 5,048 hours of movement.

Every sequence is paired with 1–3 text captions. An approximately 500-hour subset also includes temporally aligned speech or music, enabling learning across semantics, rhythm, and motion.
