# MiniMax H3 Extender Ref2VA
|
|
|
|
## Summary
|
|
|
|
Imported `MiniMax H3` continuation workflow based on
|
|
`tritant/ComfyUI_MiniMax_H3_Extender`. This is a `Ref2VA`-first extender with
|
|
shared image references, optional audio reference, Motion Context continuity,
|
|
validated clip-by-clip reuse, and final joined video/audio decode.
|
|
|
|
## Model Family
|
|
|
|
- `minimax`
|
|
|
|
## Status
|
|
|
|
- `imported-only`
|
|
|

## Developer notes
|
|
|
|
- The upstream node is built around a single horizontal sequence node instead of
|
|
a large repeated graph.
|
|
- It keeps a validated disk cache, supports `clip_by_clip` and `full_batch`,
|
|
and is explicitly designed for longer `MiniMax H3` continuation chains.
|
|
- The upstream README says it combines `Ref2VA`, Motion Context, disk caching,
|
|
per-clip prompts, per-clip seeds, and final decode/export into a simpler
|
|
flow.
|
|
|
|
## Our notes
|
|
|
|
- This import is worth keeping because it is natively `reference-to-video`
|
|
oriented and closer to Chris's actual MiniMax use than generic `t2v` graphs.
|
|
- I replaced the source repo's very specific demo clip script with a neutral
|
|
reusable starter clip state so the imported workflow opens as a practical
|
|
template instead of someone else's scene.
|
|
- The graph still uses the upstream source-leaning stack, so it is more of a
|
|
donor / comparison import than the first `3070` workflow to run.
|
|
|
|
## Required custom nodes
|
|
|
|
- `ComfyUI_MiniMax_H3_Extender`
|
|
|
|
## Required models
|
|
|
|
- `MiniMax H3` `Ref2VA` checkpoint
|
|
- matching `MiniMax H3` text encoder
|
|
- `MiniMax H3` video VAE
|
|
- `MiniMax H3` audio VAE
|
|
- optional turbo LoRA path if enabled
|
|
|
|
## Notes
|
|
|
|
- Use this when you want the upstream extender logic itself.
|
|
- For the tighter local-first variant, use the optimized companion workflow in
|
|
`optimized/image-to-video/minimax-h3-extender-3070-r2v-480p-clip-by-clip/`.
