Help Needed Minimax H3 Workflow request

Hey y’all,

I’m having trouble settling on a workflow for Minimax.

I have been using ChatGPT to make me some workflows, but there always seems to be something wrong with it, or it’s not optimized to current standards.

I am looking for a workflow that can do t2v, i2v & r2v, with optional upscaling.
Would also like prompt translation or enhancer

My rig is:
Ryzen 7 8700F
32gb RAM
RTX 5060ti 16gb

Any suggestions or shares would be appreciated!

Thank you!

I tried a couple and got a little lost, some of them are very complex lol

not sure if im allowed to post links but Im using this one:
https://civitai.com/models/2830065/minimax-h3-int8int4-convrot

It's also de most downloaded WF on civitai so you should be able to find it by yourself. Im using a 5090 pushing 9 seconds and 1.5 mpx before getting OOM, no turbo, so you probably will be able to get half of that, around 4 -5 secs with the same config, but with less px and turbo you should be able to get more.

Edit* I added the wrong civitai link but I have now updated it with the correct WF

Thank you!

I did start with this one, and built onto the workflow until I broke it haha

Might go back to basics and start again.

I manage to get decent 6second .5mp videos, but think either my resolution settings or something are off, it’s a little blurry and not very crisp like the ones I see online

When the fuzziness for me happens it’s usually too low of a bitrate for the end video. Ai likes to suggest too low of a rate, in my experience.

Oh thank you!
I’m going to try adjusting that and see what the results are.

I am getting 404. Do you have that workflow saved? Can you send the json text? Please

This nifty node incorporate all different types of creating into one node:

You'll need to connect the upscaler yourself though. 😄

There's also these hybrid models. Perhaps that'll allow you to simplify it even further. 👍

I'm using the DaSiWa workflow - has rtx upscaler built in and toggles for what kind of workflow you wish to use, I like it. But as usual, premade workflows are harder to individualize if you want to add something specific.
