nerfacto automatically downscaling to max 1500 pixels

[leyuheon1]

When I run the given nerfacto command (following the documentation exactly), it downscales to max 1500 pixels ( 50 x 30) and thus the scene is basically unrecognizable. I tried changing this by setting --downscale-factor 1 but it isn't working (stuck in training) and --downscale-factor 2 also gives max 1500 pixels. If I need at least 720p what should I do?
