Since you didn't have any "pix_fmt" argument in your ffmpeg  
x11grab-capture commandline, I presume it's something like rgb24.

You might want to try downsampling it to something like yuv422p or  
even yuv420p (=default HD video pix_fmt)?

Just add the argument like this, after e.g. the framerate:
"-pix_fmt yuv420p"
