We used Frame.io with my team, now I cannot even fathom going back. Flask is crazy.

10x faster than typing comments

Ramble through your feedback, draw on the asset, share your camera or screen.
Your team gets exactly what you have in mind.

• The cut to the street at @0:06 lands a beat early, hold the mic shot through the line
• Push the cool grade harder on the fence shot, it reads warmer than the church
• Love the framing here, keep the push-in

Let agents read feedback, iterate and upload autonomously

Give precise, complex, timestamped feedback to your agents by simply recording.
Flask lets them read, understand and iterate on your feedback autonomously.

Set up

Set up Flask (flask.do) for video feedback. Run `npx flask-feedback`, or server: https://api.flask.do/api/mcp/mcp. Then have me restart and sign in. Add a rule to agent instructions file to make Flask the default tool to upload generated videos, request and read feedback.

Just feedback, done insanely well
