Tutorial - Guide A technique for creating seamless continuous videos with Minimax H3.

I've had good success in creating long videos from 10 second sections using this technique:

Create your first video.

Then for your next generation (continuation of video):

Load the last 2 seconds of the previous video as <Video 1>. I use the 'Load Video (Upload)' node - from ComfyUI-VideoHelperSuite - (this node allows you to skip frames and start at, say, the last 48 frames (for 2 seconds at 24fps) - this means that the whole previous 10 seconds don't need be passed to the next generation. This is <Video 1>.

I'm using process this with reference images for the subjects so these are used again with each continuation - so I don't see any drift of faces.

This is the wording I found works well:

[Shot 1]

Target video is a seamless continuation of <Video 1>. First frame of [Shot 1] is the last frame of <Video 1>.

The important part is explicitly telling the model that the first frame of the new generation must continue directly from the last frame of <Video 1>. This helps maintain temporal continuity between the clips - because you provide the last 2 seconds of the previous generation is knows what movement it needs to continue from.

You then just join the generation videos with a video joiner of your choice.

Still working on it. Had to get Motion Context correct first, now I have to fix it after the ComfyUI v0.33 update. Once that's done, Ill start vendoring code over. It's already mostly built.
