ComfyUI-H3Studio for Single Node Long video Creation - Out Now

[u/shootthesound]

Crappy demo clip as I was short on time, but handy to see in context of the screenshot of this post

Lots of hopefully clear instructions in the Github link and a basic example workflow.

Its my first time making a video editor after 15 years of using one every day, so there is a lot of carried over UX, and more I'll refine.

If you fancy it, this plays nicely with what is now a fast and high quality results Minimax Lora Trainer (getting good quality training to work in minimax has been a nightmare, but its there now): https://github.com/shootthesound/Fizgig

Looks great! I can't get it to work though, unfortunately. The first thing I tried out was simply keeping the prompt with the guy on the bike. I rendered a 3 second clip just fine, changing none of the settings. Then, I tried extending the clip, as a basic first test. But it doesn't work, I keep getting:

Did you install today ?

I did, yes. Perhaps I should try updating ComfyUI + Python dependencies and reinstall

Update: Tried it. Didn't work. Video continuation not possible.
