## Developer notes
|
|
|
|
- The workflow is built around the `H3 LongVideos` node pack.
|
|
- It turns a paragraph-by-paragraph prompt into chained shots and supports `plan_only` for a non-rendering split check.
|
|
- The source README expects ComfyUI `0.31+` with native MiniMax-H3 support.
|
|
|
|
## Our notes
|
|
|
|
- This is the most immediately useful MiniMax H3 import today because it packages the long-form, audio-synced path instead of a bare checkpoint.
|
|
- The default settings are already aimed at practical use: `8` steps, `res_multistep`, `shift_video/shift_audio` at `12/3`, and shot chaining.
|
|
- Still heavy for an RTX 3070 with `8 GB` VRAM, but this is the right kind of heavy if you want a real H3 workflow.
|
|
|
|
## Required custom nodes
|
|
|
|
- `Smite79/MiniMax-H3-LongVideos`
|
|
- current ComfyUI MiniMax-H3 support
|
|
- `pysssss` for the text output panels
|
|
|
|
## Required models
|
|
|
|
- `MiniMax-H3` diffusion model
|
|
- `MiniMax-H3` text encoder
|
|
- `MiniMax-H3` video VAE
|
|
- `MiniMax-H3` audio VAE
|
|
- optional `MiniMax-H3` PDD Acc LoRA for the low-step path
|
|
|
|
## Notes
|
|
|
|
- Best first try if you want a reusable local MiniMax H3 workflow rather than another checkpoint.
