/s/<Resolution> |
No | Sets video resolution in widthxheight (e.g., 640x480) or using adaptive modes:- Both width and height set: Scales to exact size. If aspect ratios differ, stretching/compression may occur. - Only width or only height set (e.g., 1280x-1, -1x720): Other dimension auto-adjusts to maintain aspect ratio. |
