Remarks

For 16-bit video (MEDIASUBTYPE_RGB555 or MEDIASUBTYPE_RGB565), the input must be 720 x 480 pixels for NTSC, or 720 x 576 pixels for PAL. For 24-bit video, there are no size constraints on the input.

The output is always 720 x 480 for NTSC or 720 x 576 for PAL; 24-bit video is scaled to fit these dimensions.
