Testing MiniMax H3 R2V Locally: Generating a Short Film on a Single RTX 5090

lxe · reddit · 2026-08-06

Developer lxe generated a short film locally using the MiniMax H3 R2V model on a single RTX 5090 GPU and shared the complete workflow.

Core Workflow:

Used Krea 2 to generate clean reference images for characters, objects, and empty styled background scenes.
Fed these references into the H3 R2V model to generate video scene by scene, precisely prompting the opening state, actions, and camera movements.
After locking the edit, generated a matching score with Suno and mixed it in.
Finally, upscaled the video.

The author noted that the entire workflow was driven via AI on a mobile device, demonstrating strong controllability and multi-tool orchestration.
