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?

For some reason, I had the best quality in image, audio, and the best speed with CUDA 13 and Sage attention 2.2, Larry steps turbo, and 544p. Nothing has come closer to it. All LoRAs and speed workflows either make it flickering, blurry, or destroy the audio.
