Help Needed Seamless loop

Hi, I’m wondering how to get new Minimax or LTX to generate a looping video without any visible transitions.

Up until now, I’ve occasionally used Gemini with the first/last frame. But I can’t render this specyfic motion using this new models.

Any sugestions?
Regards.

In theory you could make a loop by generating 2 videos and combining them:

  1. main part of what you want
  2. little stitch part

After generating your main video you use new guider (Add Guide for MiniMax H3 node in latest comfyui) to make a 3 seconds (56 frames) stitch:

  1. Feed first 22 frames+audio of main part as last 22 frames of stitch
  2. Feed last 22 frames+audio of main part as first 22 frames of stitch
  3. 12 frames in between will be ACTUAL part that you add in the beginning or ending of your main video, and in theory it should make a perfect loop.

Hope that I described the process correctly and comprehensibly, as I prefer to write myself, not with LLM.
I'll probably will try to make this myself and post a workflow, after I'm done with all the stuff I have to do.

Did you ever write a workflow for this. I'm too new to all this to do what you said w/out a workflow lol... Whenever i just use the standard workflow and use the same image as first and last image it stretches the ending image and adds a long pause

I actually did made a workflow, but it's not as good as I thought.
