I'm surprised they don't allow UHD resolution (3840×2160). There are probably a few people in the world who can reliably tell the difference with true 4K.
An average person can't even tell the difference between 720p and 1080p.
- pflats 9y agoThey do allow it.
- olegkikin 9y agoCamera Requirements 4K Resolution: • Camera must have a true 4K sensor (equal to or greater than 4096 photosites wide). Also notice that not a single UHD camera is on the approved list.
- pflats 9y agoThe cameras have to be 4K+; the final product can be UHD. See the "IMF Master" section.
- olegkikin 9y agoI was talking about the source material from the beginning. The fact that they allow UHD in the IMF master makes it even less reasonable, because downscaled 4K-> UHD footage will have lower resolution than the native UHD footage.
- bo1024 9y agoWhen you step back, it seems to reveal an almost silly obsession with video resolution as a proxy for quality and future-proofing. It feels like it's coming more from marketing than true quality or future-proofing goals (just look at the audio standards...). On the other hand I definitely applaud their focus on having good backups and preserving the original source material.
- KaiserPro 9y agoUHD isn't technically 4k, its quad HD, hence the funny resolution. cinema 4k is 4096 wide by 2160 https://en.wikipedia.org/wiki/4K_resolution#Digital_cinema https://en.wikipedia.org/wiki/4K_resolution#Digital_cinema and predate quadHD by quite a way. firstly the better cameras are proper 4k, QHD cameras tend to be a bit rubbish. Secondly there are many more tools for dealing with cinema 4k, than QHD
