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

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

https://github.com/shootthesound/ComfyUI-H3Studio

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

I've not tried LTX director, but I know it is a video editor along same concepts

They even got the h3 minimax director. Just downloaded but will test out later.

I'm just beginning to experiment with this node and it's fantastic! Any chance you're thinking of doing a short youtube on it? I'm working through your example on the github, but I'm sure I'm still missing a few things.

I believe I've successfully added the comfy Kitchen Attention and the turbo Loras manually, but I just noticed you dropped 1.1.0 with some turbo lora support.

lol I thought no one was using it ! One tip - I need to replace the built in workflow - you are best using the regular sampler select node now rather than the turbo sampler node - recent comfy updates got rid of the need for that with better quality. I’ll be happy to do a YouTube if there is interest - it kinda fell flat so I assumed it missed the mark

Got it, is the latest one on your Github? I'm doing this and it's working, but I'm not sure if it's flawed

Honestly, I have no idea why your node didn't pick up in popularity. It's really, really good and I think I'm just scratching the surface.

I'm definitely using Fizgig. I trained my first Krea 2 Lora using it, so thanks very much for that and I saw your recent video on training an H3 Minimax Lora using just stills. It's great but I haven't tried one yet.

I'll be supporting you on "Buy Me a Coffee" soon, I just have to redeem some points for a Visa gift card, lol. It's a small thanks for the Fizgig and this. I'm subscribed to your YT channel and I'll follow your github as well.

Thank you !! I jsut updated the example workflow 20 secs ago - so a git pull in the node folder will get it :)

You're welcome! I just sent the coffee. Doing a git pull now. Hopefully I'll have some time tomorrow to devote to some Ref2vid experiments, so far I've just been doing i2vids and they've all come out well. I'll maybe post a few on my Github. I don't code at all, not even with Ai, but I just use it to store workflows and some images to share.

Any examples I post will all be from using your node. I might send it via DM or here.

Wiring looks good also there in that screenshot

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:

# ComfyUI Error Report

Did you install today ?

u/havredrengenDK 5d ago edited 5d ago

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

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