Streaming Video Editing with Easy Adaptation
Summary
The paper introduces SVEET, a framework that adapts a pretrained bidirectional video diffusion model for streaming video editing via an auxiliary branch with temporally independent self‑attention and a decoupled orthogonal training scheme. It achieves real‑time 15 FPS editing on a single H100 GPU without extra acceleration.
- SVEET adds an auxiliary branch that encodes source frames with temporally independent self‑attention and injects features into the backbone for streaming control.
- Training enforces orthogonality between controllability and causality gradients, allowing zero‑shot transfer across different backbone architectures.
- The method runs at ~15 FPS on a single H100 GPU, matching real‑time requirements without specialized hardware tricks.
- Only a pretrained bidirectional video diffusion model is needed; no full retraining of the backbone.
Engineers building real‑time generative video editors or streaming pipelines need efficient, adaptable diffusion models, and SVEET offers a practical path.
