You might try deinterlacing your material before the encoding. At least 
I can see two movement phases when looking at a still from your 
material. This will increase the efficiency of the encoding process and 
make a sharper picture. ffmpeg for instance has a -deinterlace 
parameter. Deinterlacing is usually recommended when showing material on 
a computers screen only.

Otherwise I might be wrong and you did actually deinterlace. Then it is 
not really a good one, or the "ghoust image" problem comes from 
something else. Then I do not want to have said anything.
