From what I’ve read, that’s exactly what hasn’t been done there properly… David Attenborough’s voice is deeper on UHD HD
I just thought if you were pressing one disc for the whole world you might go for the source framerate rather than convert from 50 to 60Hz.
Yep - that would fine if North American TVs could handle 50Hz or 25Hz sources. Many of the mainstream manufacturers (Sony, Panasonic etc.) don’t… It’s 59.94Hz or 23.976/24Hz only…
If you release a 1080i25, 720p50 (or 2160p25/50 UHD) disc - as a global release you’ll be deluged with returns from North America accompanied by ‘It won’t play’ complaints. (And 1080p25 isn’t an option for Blu-ray - it’s not part of the standard)
(Or a 576i25 DVD for that matter)
Meanwhile a 1080p23.976, 1080i29.97, 720p59.94 (or 2160p23.976/59.94) release will play globally… (or a 480i29.97 DVD)
Yep - that’s the downside - people have to know what they are doing…
