What problem does it solve? It removes the guesswork from checking and exporting code-built videos: opening the Remotion preview, finding the right composition, verifying a frame, and producing a finished file all happen through one guided workflow instead of scattered CLI commands. ## Core Features & Use Cases - Preview and Playback: Starts the dev server, navigates the composition list, and plays individual scenes registered in a Scenes folder for fast review loops. - Frame Capture and Rendering: Runs npx remotion render to export MP4 files into out/ and npx remotion still to capture a single frame as a PNG for verification. - Operational Safeguards: Warns that renders leave ~61MB in the system temp directory, that stills go stale after re-timing, and that exported files are the source of truth over the preview. - Use Case: After finishing a Remotion film, ask the assistant to render it; it runs the render command, reports the output path, and flags technical defects like wrong resolution or dropped frames. ## Quick Start Ask the assistant to render the finished composition to an MP4 file and tell you where the exported video was saved.
