On September 5, 2014, the Blu-ray Disc Association announced that the 4K Blu-ray Disc specification would support HEVC-encoded 4K video at 60 fps, the Rec. 2020 color space, high dynamic range (PQ and HLG), and 10-bit color depth. [87] [88] 4K Blu-ray Discs have a data rate of at least 50 Mbit/s and disc capacity up to 100 GB.
60 fps typically, some gaming monitors can do up to 540 fps; internally, display refreshed at up to 540 fps [23] [24] 60 fps typically, some can do 120 fps; internally, display refreshed at e.g. 480 or 600 fps [25] 60 fps typically.

Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing.
GoPro, Sony and other action camera competitors record video at 1080p and 2.7k at 120 fps, 720p and 1080p at 240 fps, and 4k at 60 fps. Although the video formats were designed for slowing down in post-production, the cameras generally record very high frame rates [ 7 ] in high definition with generally clear audio.
The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
On September 2, 2013 Acer announced the first smartphone, dubbed Liquid S2, capable of recording 4K video. [140] On September 4, 2013, the HDMI Forum released the HDMI 2.0 specification, which supports 4K resolution at 60 fps.

Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
