# MiniMax H3 Two-Beat SaveVideo Test

Practical test flow for `DumasH3LongVideos` that:

- uses `LoadImage` refs derived from images stored in this repo
- renders exactly 2 beats
- stays under 10 seconds total
- converts the returned image batch with `CreateVideo`
- saves the final file with `SaveVideo`

## Repo source images

- Character ref:
  `optimized/image-to-video/minimax-h3-r2v-master/references/default-character-reference.jpg`
- Location ref:
  `optimized/image-to-video/minimax-h3-r2v-master/references/default-location-reference.jpg`

## ComfyUI input names used by the prompt

Upload those repo images into the live ComfyUI input folder with these names:

- `default-character-reference.jpg`
- `default-location-reference.jpg`

The included `api-prompt.json` expects those names in `LoadImage`.

## Flow summary

`LoadImage x2 -> DiffusionModelLoaderKJ / CLIPLoader / VAELoader x2 -> DumasH3LongVideos -> CreateVideo -> SaveVideo`

## Timing

- `shot_seconds = 3`
- `2 beats`
- total target runtime = `6s`

## Variants

- `api-prompt.json`
  - short proof run
  - `2` beats at `3s` each
  - total target runtime = `6s`

- `api-prompt-realistic-16x9.json`
  - longer realistic scenario
  - `2` beats at `4s` each
  - total target runtime = `8s`

## Notes

- This is a practical API flow, not a promoted master workflow.
- The H3 node is configured for a cheap proof run, not final quality.
