MiniMax H3: 715 Sampler & Scheduler Combinations

I recently completed a controlled MiniMax H3 benchmark covering 65 samplers × 11 schedulers = 715 combinations.

The goal was to create a useful reference for ComfyUI users comparing video quality, render speed, and sampler/scheduler behavior.

Benchmark configuration

• Base MiniMax H3 model
• 20 sampling steps
• No Turbo acceleration or LoRAs
• Consistent settings across all combinations
• 49 hours, 39 minutes, 47 seconds of cumulative successful rendering time

Interactive comparison

The results are available through a free interactive website featuring individual video previews, render times, and documented failures.

This isn't intended to declare one universally best sampler or scheduler. The goal is to make the results accessible so creators can compare combinations and make their own decisions.

I'd be interested in hearing from anyone who's run similar MiniMax H3 tests, particularly with different steps, resolutions, or optimization methods.

The fixed 20-step setup is useful context. I'd still want to compare the clips before picking a favorite.

Not quite I understand your comment fully. On my website you can compare and see each of the 715 rendered videos of each sampler scheduler comparison with the direct link below

There is even a useful video that I made to show you every feature of the comparison and how you can sort them, isolate ones you like and then compare only the onse you like. I really hope this helps. The video is only a tutorial on all of the features available on the comparison page, not the actual comparison itself. Link to tutorial video is below

Thanks for publishing the individual clips and failures; that makes this much more useful than a single ranked table. I ran a smaller same-seed H3 A/B in a different setup: 5 seconds at 672×1216, 24 steps, with a Safe-cache baseline. Changing only to a beta scheduler increased total time from 198 s to 237 s and produced a substantially different take (PSNR 18.5 dB to the baseline), while my visual judgment did not find a clear quality gain. This is N=1, so I would not generalize it into a sampler recommendation.

For character-based sequences, I would be interested in a second comparison view that holds a character reference and a simple action constant, then scores identity and motion continuity alongside speed. A sampler can look great in a single clip while losing the task across cuts. I published the setup and limits of my small A/B here: https://github.com/Klimentios/Klimentios/blob/main/writing/minimax-h3-field-notes.md#8-parameter-experiments-that-did-not-justify-new-defaults
