+# 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.
