Aurora: Unified Video Editing with a Tool-Using Agent
Summary
Aurora is an agentic video editing framework that integrates a tool-augmented vision-language model (VLM) agent with a unified video diffusion transformer. This framework addresses the common issue of underspecified user requests in video editing by mapping raw input to a structured edit plan, which includes resolving textual and visual ambiguities before video generation. While existing video editing models use a single diffusion transformer for various tasks like replacement, removal, and style transfer, they typically require pre-processed inputs. Aurora's VLM agent is trained using supervised data for comprehensive edit planning and reference-image selection, alongside preference pairs for refining tool use and instructions. The framework was evaluated on the new AgentEdit-Bench and two other video editing benchmarks, demonstrating improved performance over instruction-only baselines and showing that the VLM agent is transferable to other frozen video editing models.
Key takeaway
For research scientists developing video editing tools, Aurora demonstrates a critical advancement in handling real-world, underspecified user requests. You should consider integrating tool-augmented VLM agents into your diffusion-based editing pipelines to improve usability and reduce the need for pre-processing. This approach enhances the robustness and flexibility of video editing systems, making them more practical for diverse applications.
