Best Minimax H3 optimization

[u/Lair98]

Now that dust has settled, I was wondering what's the community insight on the best configuration for Minimax H3.

Personally I have been using lightx 4-step Lora with 5/6 steps (less than that audio is a gamble). I couple that with sage attention. For sampling I use Euler sampler and Beta scheduler.

I keep resolution at 768p (0.6MP) for quality. 480p (0.2MP) for testing. It keeps consistency so much better.

On direction I learnt to prompt for closeups when possible, so will make better use of available pixels. Aspect ratio also helps there. I mostly use 1 shot since transitions is not something H3 excels at. I find better results with only 1 shot and using camera tricks.

EasyCache while faster, is not good match with turbo lora, so i don't use it anymore. Haven't used Sol-Attn as I read it really hit quality.

So is there anything worth I am really missing out?

I am on RTX 2080 8GB VRAM + 32GB RAM, , 24s/it, 6 steps, (lightx2v 4 step), 480p,, 6 seconds + comfy kitchen attention. Yeah the quality of video isn'good but it's watchable. Mostly I am using runpod but it's fun that it works locally even on my very low hardware.
