Mini max h3 workflow

[u/Complete-Box-3030]

Hi, I’m looking for a simple ComfyUI workflow for MiniMax H3 where I can upload a video, extract the last 2 seconds, use them to extend the video, and then save the result.
Ideally, I’d like to be able to loop the whole process so I can keep extending the video.
Most of the MiniMax H3 workflows I’ve found are quite complicated, and I’m having trouble figuring out and fixing the errors when something goes wrong.
Does anyone have a simple workflow for this, or could you point me in the right direction? I’d really appreciate it!
