How Rescaled to project size (FFMPEG only) works

Note: the dimensions of the frame/image are downscaled to the Scale factor; so if the Scale factor is ${\frac{{1}}{{4}}}$ and the dimension of the image is 4288x2848 pixels, that image will be downscaled to 1072x712. It doesn't matter what the Project Format is.
