| # MiniMax H3 — ComfyUI Workflows |
|
|
| 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 — all in one pass). Shared by [@BennyDaBall_OG](https://x.com/BennyDaBall_OG). |
|
|
| ## Workflows |
|
|
| | File | What it does | |
| |---|---| |
| | [`MiniMax_H3_Turbo_v4_8step_T2VA_BennyDaBall.json`](./MiniMax_H3_Turbo_v4_8step_T2VA_BennyDaBall.json) | Text → video+audio with the **Turbo v4 LoRA** — 8 steps instead of 20, ~**1.9× faster**, audio stays clean | |
|
|
| ## Turbo v4 · 8-step T2VA |
|
|
| 100% core ComfyUI nodes — **no custom node packs**. Verified with a same-seed A/B against the stock 20-step recipe: same choreography, healthy audio (peak ≈ −9 dB, zero clipping). |
|
|
| **The recipe** |
|
|
| | Setting | Value | |
| |---|---| |
| | LoRA | `minimax_h3_turbo_v4_step600_ema_pruned_comfyui` @ **1.0** (built-in *LoraLoaderModelOnly*) | |
| | Steps / sampler / scheduler | **8 · euler · beta** (no sigma-shift node needed) | |
| | Guidance | CFG-free (*BasicGuider*) — write a `Negative:` line inside the prompt itself | |
| | Resolution | 1344×768 @ 24 fps | |
| | Length | frames on a 17k+5 grid: **124 ≈ 5 s**, 243 ≈ 10 s, 362 ≈ 15 s (model max) | |
|
|
| The bundled demo prompt ships with a **fixed seed** so your first render reproduces the demo clip — flip the seed widget to *randomize* for new takes. |
|
|
| ## Getting started |
|
|
| 1. Update ComfyUI to **≥ 0.30** (MiniMax H3 nodes are built in). |
| 2. Drag the `.json` onto the ComfyUI canvas. |
| 3. ComfyUI will offer to **download any missing models automatically** (every loader node carries its download URL). Manual links below. |
| 4. Queue. First run: the console should show **zero** `lora key not loaded` warnings. |
|

|
|
| ## Tested / not tested |
|
|
| - Verified on **5-second clips at 1344×768**. Higher res (1920×1088) and longer clips are untested with this LoRA — earlier turbo versions fell apart there, so treat that as experimental. |
| - 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. |
|
|
| ## Prompt pattern that works |
|
|
| Style contract → timed beats (`0.0-0.6s: ...`) → camera lock line → an audio timeline starting with room tone at 0.0s → `Negative:` line. Dialogue inside `<d>[English] ... </d>` is spoken verbatim with lip-sync. Give the first spoken line ≥ 1.2 s of lead-in and anchor t=0 with room tone. The demo prompt in the workflow shows the full pattern. |
