Need to supply All "I"Frame GOP Structure - which codec shoudl I use?

Hi All

I HAVE searched the forums for help here but no luck

I am supplying a .mov to be played out on a DL2 system. I'm completely happy making my edit (manipulating jpegs to music), but want to check what sequence settings/codec I should use.

2 specifications I've been supplied with are..

-Closed GOP Structure should be All "I" Frames
-Color Space 4:2:0

I plan to use compressor to make the final .mov

Can anyone please recommend a codec that will match the above requirements?

Thanks

Hugh
