You’re seeing some of the limits of Compressor. Max bitrate of 40Mbps. It can’t add VBI either. I also don’t think it can do i-Frame only. IP, IBP, IBBP. I don’t claim to be a Apple Compressor expert but its limitations are why I use Telestream Episode.

[Robin lewis] “Video Format: MPEG-2 422P@ML 4:2:2
Video Bitrate: 50 mbps I Frame Only”422 check.
Bitrate 40 (fail)
GOP: IP (fail)I stopped there.
