This workflow is the 48GB high-configuration image-to-video acceleration version for MiniMax H3. It sits between the practical 24GB route and the full 80GB route, making it useful for stronger cloud GPUs or local workstations with more headroom. 
 
The workflow keeps the MiniMax H3 I2V generation structure, Qwen3-VL MiniMax text encoder, video and audio VAE routing, turbo acceleration, and final SaveVideo output. Compared with the 24GB target, this version is positioned for a more capable memory budget. 
 
This package is meant for practical ComfyUI and RunningHub users who want a ready-made MiniMax H3 graph instead of rebuilding loader, encoder, VAE, sampler, and video export connections by hand. The workflow is especially useful for speed comparison, hardware planning, and repeatable prompt tests. Keep the same source image and prompt when comparing versions so the difference you see comes from the workflow route, not from changing creative variables. 
 
Main features: 
 
- MiniMax H3 image-to-video workflow for 48GB-class hardware 
- 6x-speed acceleration setup for faster generation tests 
- Designed for single-frame driven character and scene motion 
- Qwen3-VL MiniMax text encoding and MiniMax H3 VAE components 
- 16:9 output route for tutorial, demo, and horizontal video use 
- A stronger middle option between 24GB compatibility and 80GB full configuration 
- Useful for comparing quality stability under a larger memory target 
 
Suggested workflow: 
 
Use the same image and prompt from the 24GB workflow, then compare whether the 48GB route gives better stability for complex lighting, face detail, or denser background motion. Keep the first test short and only change one variable at a time. 
 
For better comparisons, make one small test first, review identity stability and temporal motion, then raise prompt complexity only after the base route behaves correctly. When using speaking-character prompts, keep the face visible, avoid too many fast cuts, and separate action, expression, and camera instructions clearly.

<h2>MiniMax H3 Image-To-Video — 48 GB Edition</h2>
A MiniMax H3 video graph from episode 291, part of the six-times-acceleration series that compares model tier, LoRA, attention and cache settings.
<h2>Saved configuration</h2>
24 nodes / 29 links. One LoadImage. UNET <code>minimax_h3_fl2va_int8_convrot.safetensors</code>; CLIP <code>qwen3vl_32b_minimax_h3_nvfp4_awq</code>; int8 video/fp32 audio VAEs; turbo-v4 LoRA at 1; euler + beta 6 steps denoise 1.
<h2>How to use</h2>
The 48 GB image-to-video edition: int8-convrot fl2va weights with nvfp4-awq encoder. Same six-step turbo LoRA recipe; this is the tier to try if the bf16 24 GB file does not fit.
<h2>Limits and not-verified items</h2>
No inference was run for this listing: no speed, VRAM, quality, audio-sync or acceleration-factor claim is made. The "6x" in the episode title is the author's description and was not independently measured. Values are quoted from the saved nodes. H3 weights, LoRAs, encoder and VAEs are not bundled; check their licenses separately. The graph notes credit the official Comfy-Org/MiniMax-H3 model files; preserved as-is, no originality claim.
