GraftOOD method enhances video reward optimization with out-of-distribution exemplars

Researchers have introduced GraftOOD, a novel method for video reward optimization that addresses the issue of "motion collapse" by incorporating out-of-distribution video exemplars. This technique replaces some online rollouts with these external exemplars, aiming to improve video dynamics without sacrificing motion quality. GraftOOD was tested on the Wan2.1-1.3B model, showing significant increases in dynamic degree while maintaining or improving other metrics, outperforming existing exemplar-augmented methods. AI

IMPACT GraftOOD offers a new approach to improving video generation quality by balancing dynamics and motion coherence, potentially impacting future video synthesis models.

    GraftOOD: Grafting Out-of-Distribution Exemplars into Advantage-Weighted Rectification for Video Reward Optimization

    arXiv:2610.13470v1 Announce Type: new Abstract: Video reward optimization can increase proxy rewards while reducing video dynamics, a mismatch we identify as \emph{motion collapse}, including under a video-level motion-quality reward. We propose \textbf{GraftOOD}, which replaces …
