LIVEditor-14B: Lightning Unified Video Editing via In-Context Sparse Attention

Haopeng Li, Lichen Bai, Shitong Shao, Wenliang Zhong, Yingwei Song, Zeke Xie, Zikai Zhou

In-context Sparse Attention prunes low-saliency context tokens and routes queries by sharpness to cut attention latency by 60 percent while preserving editing quality.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

ISA is the first near-lossless empirical sparse framework tailored for ICL video editing, achieving ~60% reduction in attention-module latency while surpassing state-of-the-art methods across EditVerseBench, IVE-Bench, and VIE-Bench.

C2weakest assumption

That the claimed theoretical proof of query sharpness correlating with approximation error, combined with the empirical pre-selection and dynamic grouping, produces near-lossless results without introducing visual artifacts or requiring per-video retuning on real-world editing tasks.

C3one line summary

ISA prunes low-saliency context tokens and routes queries by sharpness to either full or 0-th order Taylor sparse attention, enabling LIVEditor to cut attention latency ~60% while beating prior video editing methods on three benchmarks.
