Videos and audio start playing immediately using fast streaming versions Aspect prepared during indexing - no waiting for a huge original file to load. Images render at full quality, and documents open page by page. ## Video playback The viewer is built for frame-accurate review: * Play and pause with Space, or use J, K, and L to shuttle backward, pause, and speed up - the same keys editors use in their NLE. * Step through footage one frame at a time to land on the exact frame you want. * Scrub the timeline to skim through a clip quickly. ## The transcript For any video or audio file with speech, open the transcript tab to see everything that was said: * The transcript highlights along with playback, so you can follow the dialogue as it plays. * Click any word to jump the video to that exact moment. * Search within the transcript and step through every hit. * Export the transcript to a file if you need it outside Aspect. ## Comments Review happens right on the asset. Anyone with comment access can join in. ### Comment on a moment On videos, comments are tied to a timestamp - each one shows up at that point on the timeline, and clicking it jumps playback there. You can also comment on a time range to cover a whole section, not just a single frame. On images, you can pin a comment to a specific spot in the frame. On documents, comments attach to a page, and you can highlight a passage of text and comment on it directly. ### Draw on the frame Annotate exactly what you mean: sketch freehand, or drop arrows, lines, and boxes on the frame alongside your comment. No more "the thing in the top-left, no, the other one." ### Threads, mentions, and reactions * **Reply** to a comment to keep the conversation in one thread. * **Mention** a teammate with @ to pull them in - they get notified. * **React** to a comment to acknowledge it without adding noise. * **Attach files** to a comment, like a reference image or a corrected graphic. ### Resolve what's done Mark a comment thread as resolved once it's handled. Resolved threads stay in the history, so nothing gets lost - and you can unresolve if the note comes back. Comments can be marked private, keeping them visible to your internal team only. Useful when clients and collaborators are looking at the same asset through a shared link. ## Downloading You can download the untouched original of any asset - what Aspect plays in the browser is a streaming copy, but your source file is always preserved exactly as uploaded. Select multiple items or a whole directory to download them together, and track progress in the download panel. Downloading requires download permission on the asset. See [People and permissions](/guides/people-and-permissions). ## Next steps * Bring outside reviewers in with [shared links](/guides/sharing). * Find the moment you need to review with [Search](/guides/search).
