Adobe Firefly video editor is a web-based application that enables users to edit videos directly in their browser without requiring downloads or installations. The platform provides a multi-track timeline interface where users can arrange video clips, audio, images, and text across multiple layers for complex editing projects. The editor integrates Adobe's Firefly Video Model, allowing users to generate new video clips from text prompts or images and add them directly to their timeline.

The platform supports text-based editing through automatic transcription, enabling users to edit videos by modifying the transcript rather than manually cutting clips. Users can trim, split, and rearrange content using standard editing tools while maintaining keyboard shortcuts for efficient workflow. The editor provides flexible export options in multiple aspect ratios including widescreen, vertical, and square formats suitable for different social media platforms and content distribution channels.

Adobe Firefly video editor allows users to access their generation history from the broader Firefly ecosystem, bringing previously created videos, images, audio, and other AI-generated content into their editing projects. The platform simplifies video production workflows by combining generation and assembly capabilities in a single browser-based environment, making professional video editing accessible without specialized software installation.
