ComfyUI workflow automates Minimax H3 video generation and timing benchmarks
GeroldMeisinger · reddit · 2026-08-26
The author presents an automated ComfyUI workflow that generates batches of Minimax H3 videos across various resolutions and durations, recording detailed generation times.
- Functionality: Iterates through resolution lists (608x352 to 1280x736) and duration lists (1-7s), generating videos and logging metrics for sampling, video decoding, and audio decoding into CSV files.
- Benchmark Data: Includes CSV outputs comparing generation times against resolution, duration, and step counts, tested on an RTX 3060 12GB system.
- Requirements: Relies on custom nodes including KJNodes (Timer), Crystools (Pipes), Basic Data Handling (File I/O), and the author's OutputLists Combiner suite.
This workflow is useful for developers needing to quantitatively assess video generation model performance or conduct batch tests.
