Who it is forA creator or developer about to publish a film who wants a quick quality check before rendering or sharing.

The problemErrors such as missing fonts, missing sound files, text cut off by the frame or frames that change between renders are easy to miss by eye.

The outcomeA list of problems the check found, so you can fix them before rendering the final MP4.

What you need first

  • Node 22.2 or later and ffmpeg on macOS, Windows or Linux, or the OpenFilm desktop app for macOS or Windows, which includes ffmpeg and the headless browser
  • A coding agent such as Codex or Claude Code, or any coding agent
  • Git, for Studio's saved versions
  • About 100 MB of disk space for the headless Chromium download on the first run
  • Your own API keys in Studio's Settings → Providers, only if you want generated voice, music, images or video

Steps

  1. Run openfilm look on the film folder to get a contact sheet of its frames.
  2. Look at a single frame with a time value, or a range, using the same command with openfilm look.
  3. Read the report for changed frames, page errors, fonts that failed to load, missing sound files and cut-off text.
  4. Fix each reported problem in the film files or in Studio.
  5. Render the final file with openfilm render.

Prompt for your agent

In the openfilm/openfilm repo, run `openfilm look` on the film at <folder> and list every reported problem. Expect a contact sheet and a report that names any changed frames, page errors, fonts that failed to load, missing sound files and cut-off text. Verify by fixing one reported problem and running `openfilm look` again to confirm it is gone.

Caveat. The README says the check finds changed frames and certain errors, but it does not say it will catch every visual defect, so a manual review is still needed.
