scale[=w:h[:interlaced[:chr_drop[:param[:param2[:presize]]]]]]
      Scales the image with the software scaler (slow) and performs a YUV<->RGB colorspace conversion (also see -sws).

         <w>,<h>
              scaled width/height (default: original width/height)
              NOTE: If -zoom is used, and underlying filters (including libvo) are incapable of scaling, it defaults to d_width/d_height!
                  0:   scaled d_width/d_height
                 -1:   original width/height
                 -2:   Calculate w/h using the other dimension and the prescaled aspect ratio.
                 -3:   Calculate w/h using the other dimension and the original aspect ratio.
