[MEncoder-users] mencoder: white converted to grey

[Pieter Eendebak]

Dear all,

I am trying to convert a sequence of images (either png or jpg) to a
movie. Using mencoder I can create a movie, but the color white from
the images is converted to gray in the output movie. How can I solve
this problem? mencoder command and output is included below

With kind regards,
Pieter Eendebak
