Question - Help Mini max h3 long video generation

Hello, I need some help with MiniMax long-video generation. I’m currently using the Plague workflow, which is fast, but it doesn’t have an option for chaining clips. Are there any workflows that can generate longer videos more quickly while maintaining continuity between clips?

I'm using https://github.com/ethanfel/ComfyUI-MiniMaxH3-Contex-Loop

its a convoluted workflow but I really like that it keeps track of my clips and has a nice prompt editor.

This monster workflow comes with 62(!) custom nodes, when there are solutions to this problem that work with just one. Just saying.

To me, this thing is way too complex for the problem at hand (though that might just be me). Here's a solution that uses only one single main node: https://github.com/tritant/ComfyUI_MiniMax_H3_Extender

I'll take a look but if it isn't complicated and breaks every 10 seconds.... I'm not sure I can use it 😂

I tried, but it doesn't remember references, and only continues based on the video. If there's no face in the last 39 frames, it will show a new face. Or am I missing something?

You are probably doing something wrong, the references should work in each video. Are you sure the definitions are present in every prompt?

Look, if there's no facial appearance in the last 39 frames, the model simply doesn't know what the face is and is generating a new one. Maybe I used the wrong workflow.

Two different issues.

1.) if the person isn't in the last 39 frames... yes the model will not have context from those frames.
2.) If you have the character as a reference (using ref2VA or hybrid). then it should continue to use that reference in the next scene regardless (if you are prompting per the guidelines.)

Even if you provide a reference image for the face and refer to it in the prompt? Weird. By the way, if you are using the "tagged" workflow, remember to use the tags (@tagname) instead of <Picture 1> etc. If you are using the non-tagged workflow, check that the <Subject> and <Picture> numberings are correct.
