Core Concepts
EchoReel enhances video diffusion models by extracting motion features from reference videos, improving action generation without fine-tuning.
Abstract
EchoReel introduces a novel approach to augment the capabilities of Video Diffusion Models (VDMs) in generating intricate actions by emulating motions from pre-existing videos. The Action Prism distills motion information from reference videos, enhancing VDMs' ability to produce realistic motions without compromising their fundamental capabilities. By incorporating new action features into VDMs through additional layers, EchoReel significantly improves the generation of realistic actions, even in situations where existing VDMs might fail. The framework seamlessly integrates with existing VDMs and demonstrates superior performance in generating diverse actions without directly replicating visual content from reference videos.
