# MiniMax H3 SaveVideo Tests

Practical test flow for `DumasH3LongVideos` that:

- uses `LoadImage` refs derived from images stored in this repo
- renders short beat-based clips
- stays near or 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 baseline prompts expect those names in `LoadImage`.

The new reference-quality prompt uses these live input names instead:

- `chris-character-reference.jpg`
- `chris-location-reference.jpg`

## Flow summary

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

## 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`

- `api-prompt-3beat-10s-480p-quality.json`
  - reference-quality follow-up for today's H3 live test
  - `3` beats with explicit per-beat timing: `3s`, `3s`, `4s`
  - total target runtime = `10s`
  - expects the provided live refs to be uploaded as:
    - `chris-character-reference.jpg`
    - `chris-location-reference.jpg`
  - quality-oriented settings:
    - `864x480` (`0.4 MP` at `16:9`)
    - `20` steps
    - `euler` sampler
    - `beta` scheduler
    - H3 turbo LoRA enabled

## Notes

- This is a practical API flow, not a promoted master workflow.
- `api-prompt.json` and `api-prompt-realistic-16x9.json` remain cheap proof-run variants.
- `api-prompt-3beat-10s-480p-quality.json` is the quality-biased reference test.
