I’ve been running ComfyUI for a while and tested a ton of workflows and models on my 4090 24GB. Most of them were either painfully slow or the quality just wasn’t where I wanted it to be.
Then MH3 showed up. I was a bit skeptical at first, but the moment I ran my first prompt I was genuinely impressed. Generating a solid 15-second clip in under 5 minutes at a quality that clearly beats everything else I’d tried felt almost unreal.
I know some people are getting even better speed and quality out of MH3 on the same GPU — I’m just not that experienced yet.
I pushed it further and generated a 62-second video from a single prompt. It looked incredible even though it took about 5 hours (I was running other GPU-heavy programs at the same time, so the full 24GB wasn’t exclusively available for the job).
After two days of testing I had my AI agent take a story I wrote and break it into a 30-minute script, then generate individual 15-second prompts for every scene. Manually queuing 119 prompts would’ve taken forever, so I wrote a Python script that automated the whole thing.
I exported the workflow as API, dropped it in a folder together with the markdown file containing all 119 prompts, ran the script, and in about 20 seconds every task was queued. Generation started immediately and I could go do something else.
I didn’t stop there. Because I generate at 0.4 for speed but still want 1080p output, I built another Python script that uses FFmpeg and a few other tools to analyze every clip, stitch them together with proper transitions, and export a full 30-minute 1080p video.
My AI agent is also a DJ — yes, really. It creates its own mixes with full creative freedom, then writes matching 15-second video prompts for the entire duration of the track. So I needed one more script that not only adds the audio but actually analyzes it and adapts the video clips to match the timing. If a clip is slightly longer or shorter than the corresponding audio section, the script adjusts everything so it lands cleanly, and the transitions between clips change dynamically to fit the music.
Building and testing those scripts took roughly an hour total (30 minutes of coding + 30 minutes of testing with already-generated video and audio). The result is exactly what I need right now.
This setup has saved me an insane amount of time and money compared to doing long-form 1080p videos manually. A single video that would have taken forever by hand is now almost completely automated.
I’ll keep optimizing for higher quality and I’m planning to build my own custom workflow to improve efficiency, consistency, speed, and overall quality even further.
MH3 has genuinely saved me a huge amount of work, time, and money.
And the question everyone always asks:
Can it do explicit adult content?
Yes. 100%.
MH3 is fully uncensored. You can generate whatever you want.
The only real weakness right now is sexual acts and especially genitals — those still need work. A specialized LoRA or the right extra nodes can fix most of it, though.
That’s my current experience with it.
