MiniMax H3 Draft Continue

Preview first. Continue when you're happy with the composition.
MiniMax H3 Draft Continue adds a Preview → Review → GO workflow to ComfyUI. Review an unfinished first-frame estimate after the first 3 of 6 sampling steps, then use GO to finish the same generation.
GitHub — installation, latest workflows and documentation
Two workflows in one ZIP:
T2VA Neon: a text-only neon scene with START/END bounding-box guidance.
I2VA Cyberpunk: a two-reference scene featuring a courier and a small rover. Both reference images are included.
Both templates use H3 Structured Canvas for BBOX layout and timeline controls. Install both custom-node repositories, open a workflow, and select your installed H3 model files. For I2VA, load the included images into the A/B image nodes.
Short English tutorials: T2VA walkthrough · Two-image I2VA walkthrough
The Preview is an intermediate estimate, not final image quality. GO resumes sampling; it does not extend the video duration. Model weights are not included.

Hi, this looks really interesting but it appears your link to the H3 Structured Canvas on github is down?
Thanks for letting me know! The GitHub repository was private by mistake, but I’ve now changed it to public. The link should work now. I appreciate the heads-up!
@ukr8b3g201 No worries and thanks for taking the time to translate all this into English! I know it adds a lot of time for folks like yourself. I hope you see the benefit that it allows you to find a larger audience and it also makes it a lot easier for some of us to engage ;)
Gave it a quick test and was able to duplicate your sample on the first try so off to a good start. Now I will work on breaking it. Which apparently is my main talent....
@markfjohnson Thanks, I really appreciate that!
And yes, making the English documentation takes some extra time, but it is absolutely worth it if it makes the project easier for more people to use, test, and discuss.
Glad to hear the sample worked on the first try.
And honestly, “breaking it” is exactly what I need now. 😄 If you find any strange behavior, edge cases, or something that clearly should work but doesn’t, please let me know the settings and steps you used to reproduce it. Those reports are extremely useful for improving the node.
Have fun trying to break it!
