A user tested the Minimax H3 video generation model across different step counts, emphasizing that 25 steps should be the lowest recommended setting.

Test environment and results:

Hardware: 12GB VRAM / 32GB DRAM
Resolution & Duration: 832x480, 10 seconds
15 steps (7m22s): Exposed critical flaws of a lower step count in a specific generation.
20 steps (8m25s): Quality improved.
25 steps (10m30s): Best results.

The author suggests that after completing phase 1, you can use a Turbo LoRA to upscale the video to 1344x768 in just 4 steps.
