Television Blue Planet II

[VeevaVee]

That's what I said! Some of the underwater dolphin-y stuff seems very CGI. Obviously, the satellite-y stuff with a shot of the planet is. My wife thinks I'm mental for thinking that though.

Glad the debate rages on in here as well.

Yeah, sometimes they look and move just slightly different from one shot to the next, so appears to be CGI mixed with real. If it's just because of some fancy camera or post work then they should be a) surely only using those cameras for the same dives and b) not editing one shot so differently to another, which seems unlikely. I doubt they'd mess up either of those things like that.
