# MiniMax H3 β ComfyUI Workflows
|
| 16 |
+
|
| 17 |
+
Drag-and-drop ComfyUI workflows for [MiniMax H3](https://www.minimax.io/blog/minimax-h3), the omni-modal video model that generates video **with native stereo audio** (voice, SFX, room tone β all in one pass). Shared by [@BennyDaBall_OG](https://x.com/BennyDaBall_OG).

## Workflows

| File | What it does |
|
| 22 |
+
|---|---|
|
| 23 |
+
| [`MiniMax_H3_Turbo_v4_8step_T2VA_BennyDaBall.json`](./MiniMax_H3_Turbo_v4_8step_T2VA_BennyDaBall.json) | Text β video+audio with the **Turbo v4 LoRA** β 8 steps instead of 20, ~**1.9Γ faster**, audio stays clean |
|
| 24 |
+
|
| 25 |
+
## Turbo v4 Β· 8-step T2VA
|
| 26 |
+
|
| 27 |
+
100% core ComfyUI nodes β **no custom node packs**. Verified with a same-seed A/B against the stock 20-step recipe: same choreography, healthy audio (peak β β9 dB, zero clipping).
|

+
|

+
**The recipe**
|
| 30 |
+
|
| 31 |
+
| Setting | Value |
|
| 32 |
+
|---|---|
|
| 33 |
+
| LoRA | `minimax_h3_turbo_v4_step600_ema_pruned_comfyui` @ **1.0** (built-in *LoraLoaderModelOnly*) |
|
| 34 |
+
| Steps / sampler / scheduler | **8 Β· euler Β· beta** (no sigma-shift node needed) |
|
| 35 |
+
| Guidance | CFG-free (*BasicGuider*) β write a `Negative:` line inside the prompt itself |
|
| 36 |
+
| Resolution | 1344Γ768 @ 24 fps |
|
| 37 |
+
| Length | frames on a 17k+5 grid: **124 β 5 s**, 243 β 10 s, 362 β 15 s (model max) |
|
| 38 |
+
|
| 39 |
+
The bundled demo prompt ships with a **fixed seed** so your first render reproduces the demo clip β flip the seed widget to *randomize* for new takes.
|
| 40 |
+
|
| 41 |
+
## Getting started
|
| 42 |
+
|
| 43 |
+
1. Update ComfyUI to **β₯ 0.30** (MiniMax H3 nodes are built in).
|
| 44 |
+
2. Drag the `.json` onto the ComfyUI canvas.
|
| 45 |
+
3. ComfyUI will offer to **download any missing models automatically** (every loader node carries its download URL). Manual links below.
|
| 46 |
+
4. Queue. First run: the console should show **zero** `lora key not loaded` warnings.
|

## Tested / not tested
|
| 59 |
+
|
| 60 |
+
- Verified on **5-second clips at 1344Γ768**. Higher res (1920Γ1088) and longer clips are untested with this LoRA β earlier turbo versions fell apart there, so treat that as experimental.
|
| 61 |
+
- Few-step audio blowout is the classic turbo failure mode; this v4 @ 8 steps is the combo that passed. If you drop steps further, check your audio peaks.
|
| 62 |
+
|
| 63 |
+
## Prompt pattern that works
|
| 64 |
+
|
| 65 |
+
Style contract β timed beats (`0.0-0.6s: ...`) β camera lock line β an audio timeline starting with room tone at 0.0s β `Negative:` line. Dialogue inside `<d>[English] ... </d>` is spoken verbatim with lip-sync. Give the first spoken line β₯ 1.2 s of lead-in and anchor t=0 with room tone. The demo prompt in the workflow shows the full pattern.
