| # Checked 2026-10-22 on one B200 at the default 480: each mode renders in about 60 s and peaks at | |

| # ./examples/demo.sh edit /path/to/MiniMax-H3 # lora/edit: remove wind turbines, 2 references | |
| # ./examples/demo.sh swap /path/to/MiniMax-H3 # lora/swap: recast a person, 2 references | |
| # | |
| # Inputs are in examples/inputs/<name>/: source.mp4 (832x480, 24 fps, with the source | |
| # soundtrack), and refN.png, frames of the target video painted in an image editor from | |
| # source frame --pin. The prompt is examples/prompts/<name>.txt, the exact prompt behind | |
| # the clip of the same name in examples/media/. | |
| # | |
| # --frames must stay at the value below: the prompt's timestamps are written for it. | |
| # The clips on the model card were rendered at the 720 class (SHORT_EDGE=736), so the | |
| # default 480 run will not match them pixel for pixel; it should show the same edit. | |
| # If the edit run comes back with the turbines still there, or the swap run with the pizza | |
| # maker instead of the pineapple mascot, the LoRA did not load. | |
