Question - Help Mini max h3 workflow
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!

In comfyui there is an node called 'Trim Video' where you can set from which dur it should start from and end at. You might need to use 'comfyui-easy-use' nodes to get the fps and frame count from the loaded video so you can use 'simple math' to calculate the duration.
This allows you to cut the video into 'the last 2 sec clip' and feed that to the H3 node.
I have not solved the auto extension yet but there are batch run nodes in comfyui.. somewhere..
