only available in 720p.


Seriously canon.

you want us to buy a 4k camera with us only having seen the results in 720p on vimeo?

[OlegKalyan]

in vimeo look pretty much like the rest of the good stuff on vimeo, no more, no less

1080p sample http://vimeo.com/41110723 tons of aliasing in hospital

Didnt really notice the aliasing but i wasnt looking for it really hard.

that's no aliasing on the ceiling.  those are aliens going through the air ducts.  7 meters!

[christianhubbard]

still not sure that everything you pointed to is aliasing..

And no, the file you linked is still 720p.
Please check and make sure you don't have scaling turned on by accident.

I downloaded the file from my cache, it was 640 x 360. Please check where you got the 720p from.

And of course you get aliasing. You can't tell if it was in the 4k original, but it is produced by downscaling, where one pixel must represent 3, 4, 5 original pixels with different values. If the patterns overlay, you get moire. Come on, this can't be news to you. I just wonder why so many people seem to believe it's magically going to stop with the introduction of 4k.

[christianhubbard]

But the file is HD on Vimeo ?

[shijan]

There is a button DOWNLOAD there. The aliasing is more visible in motion, not in still grab.

He's right, unless that they did something in post that video shows real aliasing!

I'm talking about the 1080p file of course

just for test: classic Kodak test image in 2K and 4K. in this image i combine 2k and 4k areas. Did you see where one ends and another begins? Funny isn't it?
