How Animals Dance (When You're Not Looking)

AI Summary

This work addresses the challenge of jointly ensuring musical synchronization and choreographic structure in animal dance video generation. Methodologically, it formulates animal dance as a beat-aligned, choreography-aware graph optimization problem, integrating automatic beat detection, mirror-pose image generation (to explicitly model bilateral symmetry), and text-to-keyframe synthesis driven by GPT-4o—requiring only six sparse textual prompts or keyframes to construct a structured pose sequence. High-fidelity intermediate frames are then synthesized via a video diffusion model. To our knowledge, this is the first approach enabling choreography-aware modeling and end-to-end music-aligned generation for animal dance. It robustly produces 30-second, high-fidelity dance videos across diverse species and musical genres, significantly lowering the barrier to professional-grade animal dance content creation.

Abstract

We present a keyframe-based framework for generating music-synchronized, choreography aware animal dance videos. Starting from a few keyframes representing distinct animal poses -- generated via text-to-image prompting or GPT-4o -- we formulate dance synthesis as a graph optimization problem: find the optimal keyframe structure that satisfies a specified choreography pattern of beats, which can be automatically estimated from a reference dance video. We also introduce an approach for mirrored pose image generation, essential for capturing symmetry in dance. In-between frames are synthesized using an video diffusion model. With as few as six input keyframes, our method can produce up to 30 second dance videos across a wide range of animals and music tracks.
