DepriveD - MiniMax H3 All-in-One HIGH-SPEED Workflow
A simple, fast, high-quality MiniMax H3 workflow designed for consumer cards.
This is a dual-mode All-in-One:
T2V / FFLF path
Reference path (images + videos + audio)
A single switch at the top forces only one path to be active at a time so you can’t accidentally run both.
Core Features
7 + 3 two-pass latent upscale (using minimax_h3_latent_upscaler_3d_bf16.safetensors)
Total of only 10 steps for high-resolution results that look like they were generated fully at the final resolution
You get a quick first-pass preview you can examine before the second pass finishes — so you can see if the video is going in the direction you want without waiting for the full generation
Optional FPS boost (leave at 24 to disable, or set to 30/48 etc.)
Optional RTX Video Super Resolution on top (2.0× recommended, 1.5× also works well)
Clean parameter panels — everything important is exposed, the rest is hidden
Preset resolutions (all correctly divisible by 32 for the latent upscaler)
Simple duration slider
Optional LoRAs
Full media loader for the Reference path (9 images / 3 videos / 3 audios) with resize, crop, trim controls inside the panel
How to Use (Quick Start)
Choose Resolution (or click the wheel to set your own — must stay divisible by 32)
Choose Duration
(Optional) Add LoRAs
Write your prompt
Hit Run
That’s it. Everything else has good defaults.
Recommended Starting Settings
First Pass Steps: 7 (6 or 8 looks good too)
Second Pass Steps: 3 (you can try 2 for a bit more speed)
First Pass Denoise: 1.0
Second Pass Denoise: 0.2–0.3
Turbo LoRA Strength: 1.0 (lowering requires more steps)
Video Shift: 12.0
Audio Shift: 3.0
Increasing steps much higher with the Turbo LoRA will start burning the image. The starting values above are a strong baseline.
Important Notes
Pictures do not save automatically. Right click any of the video outputs to save, OR set them to save instead of preview.
The entire complex wiring is hidden behind the LoRA panels on each path.
This is a new model and the community is still experimenting — feel free to try different settings.
Between Sage Attention, the latent upscaler, and the Turbo LoRA, generation speed on a 5070-class card is competitive with (and in many cases faster than) typical LTX workflows while keeping strong quality.
