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.
