FrameMorrow selects historical video frames by predicting future needs for better long-horizon generation

FrameMorrow improves long-horizon video generation by predicting compact prospective tokens that represent future information needs, guiding selection of relevant past frames. This plug-and-play method enhances consistency, quality, and action alignment across 11 models and 5 benchmarks with minimal overhead.

Based on the paper FrameMorrow: Future-guided Frame Selection with Prospective Tokens for Long-Horizon Video Generation by Bo Yin, Xiaobin Hu, Jiaqi Zhao, Shuicheng Yan

Challenges in long-horizon video generation and historical frame selection

Long-horizon video generation requires models to maintain coherent subjects, objects, and scenes over extended sequences, but the model's limited input window means earlier generated content gradually falls out of scope, risking inconsistencies in appearance and scene revisits.

Retaining all past frames is computationally expensive and redundant, so selectively preserving historical information that is relevant for future generation is essential.

Existing methods typically select historical frames based on their relevance to the current content, but this can miss frames that appear less relevant now but are important for future generation steps, motivating a future-guided selection approach.
