I'm not sure what degradation you are worried about.  As long as the bandwidth of the video is below 325MHz and the input/output terminations are correct then you should not see any problems.

What formats are going to be using?

    If we you take 5Mhz as example from input Video Generator  . what are the things to be take care off while designing .

    And would liek to know the Gain details at these frequency .

    The AD8108 has a gain of 1, while the AD8109 offers a gain of 2.  The frequency response is shown in the data sheet figures.

    While designing pay attention to clean power sources, good decoupling and good routing.
