Can I scale to a customized size?

[AstolfoGPA]

I´m trying to upscale, keeping the proportions, but its deforming the video.
The input is 512x720 but is upscaling to 720x1280

I trained the engine up to 1024, due to my lowVram (6Vram)

is there any way to keep the proportions?

I change the init.py code, to create my customized size, I create a 640x900, its returning a 640x904 video, and proportions looks great.

setting resize_to to none should preserve the original aspect ratio
the final size will only be 4 times bigger
