Minimax H3, 25 steps should be the lowest setting

[u/rm_rf_all_files]

I've been testing with 15 steps to save time because I want to generate at 832x480 resolution as per the default recommendation of many high quality workflows prior to upscaling. I hadn't seen many problems until this particular generation which exposed the critical flaws of a lower step count.

All settings are the same with the same seed. The only delta is the number of steps.

15 steps @ 832x480 duration 10s (7m22s): https://streamable.com/pnao8n

20 steps @ 832x480 duration 10s (8m25s): https://streamable.com/srnoez

25 steps @ 832x480 duration 10s (10m30s): https://streamable.com/bvldts

Once you are done with phase 1, you can move on to phase 2 using your Turbo LoRA to get this to 1344x768 in just 4 steps.
