InfinityEdit: Infinite Video Editing with a Lightweight Edit-Ignition Adapter

TL;DR - InfinityEdit is a lightweight adapter that lets streaming video generators apply instructions to future video chunks rather than editing only fixed-length clips. It enables ongoing applications such as live-game restyling and camera changes while aiming to preserve continuity and stability across repeated edits.

• Defines “infinite video editing,” where edit requests arrive over an unbounded sequence and affect subsequent generated segments.
• Uses history cross-attention for source continuity, causal temporal self-attention for forward-only temporal cues, and edit cross-attention for instruction conditioning.
• Activates the adapter only when a new edit arrives; later chunks use the original generator with a reset anchor frame.
• Introduces a task-specific data-collection pipeline and reports stable, faithful continuation across accumulating edit sequences.
