1. Your mencoder command line is missing.
2. Consider using FFmpeg, MEncoder is not actively maintained anymore. Atm, many
of MPlayer's filters are ported to (FFmpeg's) libavfilter, if the particular
filter you need is not ported yet, consider hiring somebody.
3. MPlayer (FFmpeg's) software scaler typically only supports YV12, and people
usually complain that they are loosing precision (esp. if the input format is 10
bit). Adding dformat=yv12 or similar will instruct the scaler not to output a
better quality, please read the documentation for more details on scaler
