# MiniMax H3 3070 Single 10s 1152x640 R2V Master
|
|
|
|
## Summary
|
|
|
|
Best-current single-shot `MiniMax H3` `reference-to-video` master for a
|
|
`3070 / 8 GB` box when the goal is one strong `10s` clip before post-upscale.
|
|
This is the first proven higher-resolution step above the safer `480p` chain
|
|
masters while still completing locally.
|
|
|
|
## Status
|
|
|
|
- `best-current-single-10s-r2v-master`
|
|
|
|
## Workflow asset
|
|
|
|
- `workflow.json`
|
|
|
|
## Built from
|
|
|
|
- `optimized/image-to-video/minimax-h3-best-current-r2v-master-480p-3x10s/`
|
|
- the successful `1152x640` max-resolution probe run from
|
|
`tmp/comfyui-maxres-probe/2026-08-16T21-36-15-454Z/`
|
|
|
|
## What this proves
|
|
|
|
- `1280x704` OOMed on the tested `3070 / 8 GB`
|
|
- `1216x672` OOMed on the tested `3070 / 8 GB`
|
|
- `1152x640` completed successfully as a single `10s` `R2V` render
|
|
|
|
## Key model stack
|
|
|
|
- `minimax_h3_ref2va_pruned_int8_convrot.safetensors`
|
|
- `qwen3vl_32b_heretic_minimax_h3_nvfp4.safetensors`
|
|
- `minimax_h3_video_vae_int8_convrot.safetensors`
|
|
- `minimax_h3_audio_vae_fp32.safetensors`
|
|
- `minimax\minimax_h3_turbo_v4_step600_ema.safetensors`
|
|
|
|
## Main changes
|
|
|
|
- raises the working canvas to `1152x640`
|
|
- keeps the single `10s` duration target
|
|
- keeps the low-VRAM attention and chunked feed-forward path
|
|
- keeps the latent upscale stage plus `RTXVideoSuperResolution` hook for the
|
|
post-pass workflow shape
|
|
- preserves the exact proven prompt graph instead of prematurely generalizing
|
|
away the validated settings
|
|
|
|
## When to use this
|
|
|
|
- use this when you want the best current single `10s` local MiniMax render
|
|
before RTX upscale
|
|
- use the `480p` chain masters when the priority is longer continuation or
|
|
safer multi-clip iteration
|
|
|
|
## Notes
|
|
|
|
- The bundled prompt and image references are the validated probe example.
|
|
- Replace the demo reference image, prompt text, and output prefix for your own
|
|
run after loading the workflow.
|
|
- Treat `1152x640` as the current confirmed ceiling for this graph on the
|
|
tested machine until a tighter probe proves otherwise.
