Max GOP/keyint for 720p content

[Biggiesized]

If I have 720p60/50/23.976 content, what's the max key interval?

EDIT: I'm using the Park Run sequence as the source so therefore it is 720p50, but I figured I need to know the other 720p formats as well.

If you're asking about Blu-ray compliance of the GOP setting, then you should use rounded-up framerate for GOP size with progressive content and doubled framerate (or rounded-up number of fields) with interlaced sources...

GOP=24 for 720p23.976
GOP=50 for 720p50
GOP=60 for 720p60
...
GOP=50 for 1920x1080i25

And if the maximum bitrate isn't higher than 15mbps you can use "Large GOP"

GOP=48 for 720p23.976
GOP=100 for 720p50
GOP=120 for 720p60
GOP=100 for 1920x1080i25

And if you're doing anything else in the world other than encoding to author a Blu-ray disk, ignore the above two posts...
