What is 4K video?
4K is a new resolution standard designed for digital camera and computer graphics. 4K format was named because it has 4000 pixels horizontal approximately. It has following advantages: higher image definition quality, more detailed picture, better fast-action and larger projection surface visibility.
4K video renders more than four times higher image definition than 1080p resolutions. 4K format can’t have the change in horizontal resolution, so changes in aspect are 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|
