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

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.
