Prompt staging · review loops · rendered frames
A Hudson-powered creative workspace for staging prompts, reviewing cuts, and rendering product videos before the final frame. Mark up a take; the agent rewrites the source. Works for Remotion compositions, Hyperframe motion graphics, music tracks, and animated logos.
The revise loop
Preframe treats the composition as text, not the timeline. Reviewers leave notes on a finished video; the model uses those notes to rewrite the Remotion source; the studio renders a new take.
Notes are timestamped, rect-anchored, or general feedback. The model sees all three plus the composition source.
Two stages: revise-brief proposes a small plan you can confirm. revise-render rewrites the composition and queues a new render.
What it is
The catalog studio is where you work. The revise loop wires it to the source.
Catalog
Captures, music tracks, animated logos, and rendered Hyperframes — indexed together with scenes, transcripts, vision tags, and storyboard frames.
Reviewer
Annotate frames with rects, zooms, and feedback. Leave the same kind of feedback on music tracks and motion graphics. Everything serializes into the brief.
Composer
Two engines: Remotion for programmatic video, Hyperframes for single-file motion graphics. Plus music generation from a prompt and animated logos from an SVG drop.
Four moves
Drop a screen recording in public/inbox/ or render a fresh composition with bun run studio. The catalog scanner picks it up on next build.
Open the take in the catalog detail view or the full-screen review modal. Drop annotations on the frames that need changes. Leave general notes for anything that isn't a single moment.
Submit the notes. The brief stage proposes a change plan; you confirm or edit. The render stage rewrites the composition and queues a new job.
Compare takes side-by-side. The catalog stages live moves: source → wip → final. Hand off the final MP4 or the source TSX — they always agree.
