The colors really pop in this sequence of the movie, Tron.  I had to try a redo.

After playing with saturation and scaling filters I found I prefer a 20% boost for saturation (mencoder switches -vf eq=0:1.2) and scaling filter 6 (mencoder switches -vf scale=<width>:<height> -sws 6). After trying all combinations of the filters I learned filter 6 is "luma bicubic/chroma bilinear".

I think the colors are great.  Wish I could do something about the "swimming pixels".  I wonder if this a random aspect of dithering from one frame to the next. 
The video sequence has an alternate music track.  I didn't realize it until well into the process.  I decided I like that track.
