It watches the actual video
The agent looks at rendered frames rather than trusting the plan. It checks that people can read the title, follow the action and hear every word to the end.
It finds problems. Then works on them.
The agent checks the picture, the sound, the timing and the export, fixes what fails and checks again. Whether the video says what you meant is still your department.
videoFn is a Mac video editor that Claude or ChatGPT can drive. Describe the video, watch it come together in the preview and give notes. If you'd rather fix something yourself, the editor is right there.
review the draft and fix anything that fails
measuring title contrast against the footage
reviewing the title against the moving background
adding a plate behind the title
checking the title again with its contrast plate
One example of automatic review: a title gets a background so it stays readable over moving footage. The checks below cover much more than text.
The agent looks at rendered frames rather than trusting the plan. It checks that people can read the title, follow the action and hear every word to the end.
Here, the title loses contrast against moving footage, so the agent puts a background behind it.
The changed title gets reviewed again, like every other fix. The exported file gets its own checks for frames, duration and audio, because exports have been known to surprise people.
The checks catch mistakes. They can't tell you whether the video is any good. Watch the preview, say which odd choices were deliberate and fix things in the editor if you like.
Also: tidy up your recording, animated text, edit video with claude and everything else.
Fewer surprises after you press Export.
