Video DACs ADV7123-EP and ADV7393 output opamp driver circuit

I'm using Video DAC ICs ADV7123-EP and ADV7393 in my design to generate PAL signals. I need to drive two video multiplexer inputs from the output of each DAC. Please find attached the overview of design. Please help me choose opamp driver circuit such that the video signals do not deteriorate before sending the signals to outside world.

For full galvanic isolation might be accomplished using video transformers however I do not have any experience with this path…
