What is different between 4k and 4k wide and 4k HD?

I believe just different aspect ratio's. You can use this "tool" from RED to see how each format "looks". Start at "Red Mysterium X at 4K" and the scroll down to get the different views.

Hope this helps.

They are different cropped aspect ratios. 4K is the cinema standard 4096x2160 1.9:1, 4KHD is the UHD standard 3840x2160 16:9, and 4K wide is the scope standard 4096x1716 2.40:1.

Having the options in camera also help on the compression ratio you can use

 

[Daniel Leung]

what would you guys say is the most common standard?

4K "full" is 16:9 like HDTV - and gives you widest field of view on your lens/biggest sensor. This is what we almost always use on red One MX, and I would imagine a popular choice on Scarlet as well

RED's 4K WS is actually 4096x1708 pixels. I've wondered why it's not the standard height of 1716.

Hmmm. When I think "full" I usually think of the full chip which is 1.89:1(essentially the DCI spec), NOT 1.78:1 aka 16/9 the HD spec.

I believe 4K full refers to the entire sensor. 4KHD is the same aspect ratio as 16:9.

Thank you all.

Short answer:

- 4K Full = 1.9:1 aspect ratio (4096x2160)
- 4K HD = 16x9 (1.78:1) aspect ratio (3840x2160)
- 4K WS = 2.37:1 aspect ratio (4096x1728)

HD refers to all of the broadcast variants of the 16x9 resolution.

WS refers to the wide screen aspect ratio that many films prefer to shoot in, from which you can choose to crop your 2.40:1 or 2.35:1 or whatever.

Full refers to maximum format size of the full sensor which is normally 1.9:1, with the except of Epic Dragon as 6K FF is 6144x3160 1.94:1.
