Scaling makes very little sense with lossless encoding.

Which video player are you using for playback?

If your input is RGB and you want lossless encoding (and 
qtrle and png do not provide acceptable results because 
of the specific input) use ffv1 or libx264rgb, what you 
do above does not make sense imo.
