MiniMax-H3 Turbo LoRA — Studio

Video and a synchronized stereo soundtrack out of a single denoising pass, in as few as four sampling steps instead of twenty. The model card carries real guidance about which checkpoint to use and when — this turns that prose into a decision you can make in two clicks, and hands you the command.

1 · Which checkpoint

How many sampling steps can you afford?
How much motion is in the shot?

v4 · step 600 · EMA — the current best checkpoint.

2 · Steps and strength

SettingValueWhat happens if you leave the range
Steps 4–8, 6–8 preferred Below 4, the sampler has too little to work with. Past 8 it stops helping and starts introducing over-sharp artifacts.
LoRA strength 1.0 Tuned for 1.0 across the whole 4–8 range. Only move it for a specific misbehaving clip: blurry ghosting → 1.05–1.2; over-sharp grain → 0.8–0.95.
Scheduler simple Leave it. The custom sampler is built around it.
Base model any Full (bf16, int8_convrot) and pruned variants all work — one LoRA file covers every base.

3 · The command


      
      

generate.py is self-contained but still needs a ComfyUI checkout for the H3 model, VAE and text-encoder definitions, plus the base weights from Comfy-Org/MiniMax-H3.

4 · Or wire it in ComfyUI

  1. Install ComfyUI-MiniMax-H3-Turbo (or search “MiniMax-H3 Turbo” in ComfyUI-Manager), and drop the .safetensors into ComfyUI/models/loras/.
  2. Start from the official MiniMax-H3 workflow, then make exactly two changes:
  3. Insert MiniMax-H3 Turbo LoRA between the model loader and the sampler.
  4. Feed SamplerCustomAdvanced from MiniMax-H3 Turbo Sampler, scheduler on simple, steps ≥ 4.
  5. Everything else stays as in the official graph — t2v and i2v both work.
