Comfy and MiniMax have teamed up for a two-week challenge with awesome prizes and four ways to win! Submit by September 1st at 9:00pm PT and see all details here.

How It Works

Make something up to 90 seconds in length where the sound and the motion are inseparable. Dialogue, foley, ambient, a beat driving the cut...whatever direction you want!

After sharing your video file and workflow on this thread and through our submission form, a joint panel of creative technologists from Comfy, MiniMax, and special guest judges from the community will review each submission.

Then, join us on September 2nd for a special Comfy livestream where our guest judges will give live feedback on the top 10 submissions! Join the livestream here.

Both the Comfy and MiniMax teams will be monitoring this thread and #minimax-h3 in the Comfy Discord to give light support.

Share on socials and tag #comfyH3 for a chance to be reposted or featured!

Judging Criteria

We’re looking for entries that best show what H3 makes possible: audio and visuals created together.

Grand Prize: Best Overall

The top Best Creative and Best Technical entrants advance to a final round where our panel of judges selects winners by discussion.

Best Creative

• Audio sync realism and intentionality (0-5)
• Creative execution and originality (0-5)
• Deliberate craft (0-5)
  • Evidence that you’ve actually shaped the result beyond prompt engineering. Judges will look for modified/non-default parameters, multiple linked passes visible in the workflow structure, or a couple sentences describing what was tried and changed

Best Technical

• Workflow quality (0-5)
  • Annotated, clean, replicable by someone else
• Community value (0-5)
  • Would this actually help someone else?

🏆 Built with MCP Bonus 🏆 Comfy MCP lets you drive Comfy using natural language and your agent locally and on Cloud! Pro tip: use it to choose the best H3 model version or optimize your workflow for your hardware.

• Effectiveness (0-5)
  • Did the agent meaningfully drive your process, not just generate one line?
• Insight value (0-5)
  • How much the shared prompt teaches the community about prompting H3 through MCP
• Output quality (0-5)

The Fine Print

• Limited to one submission per person, 90 seconds maximum length.
• A major portion of your piece must be built in ComfyUI using H3. Other tools, models, or techniques you want to combine are fair game.
• All submissions must be lawful, SFW, and must not contain unlicensed IP or likenesses.
