What is 4k Video Resolution?

4k is a new resolution standard designed to digital cinema and computer graphics. It's advantage in the fact that it provides for a higher image definition quality, more detailed picture and offer better fast-action and larger projection surface visibility.

4k is called so due to its approximately 4,000 pixel horizontal resolution as opposed to standard 1080p and 720p resolutions that are called so due to their vertical resolution. The new standard renders more than four times higher image definition than that of 1080p.

This format provides for no change in horizontal resolution, and change in aspect is made through the vertical resolution. For example 4096×2304 is a frame size with aspect 16:9 and 4096×3072 — 4:3. The digital video resolutions examples:

Full Aperture 4k  4096 x 3112  12,746,752 pixels
Academy 4k  3656 x 2664  9,739,584 pixels
Digital Cinema 4k  4096 x 1714  7,020,544 pixels
Digital Cinema Aperture 4k  3996 x 2160  8,631,360 pixels

YouTube enabled 4k video support in the middle of 2010. Since it is the highest resolution format available to comsumer, it has a great potential. It is quite possible that this format will be increasingly in demand by the new YouTube digital video data delivery services in near future.
