Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [ 4 ] encoded using High-Efficiency Video Coding . [ 4 ]
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.
30 frames per second. Samsung Galaxy Note 3 (2013) [a] (Snapdragon model) – The first mobile phone with 2160p at 30fps. Samsung Galaxy A8 Star (2018) – First Galaxy A-series device with 4K recording. Apple iPhone 6S / iPhone 6S Plus (2015) – The first iPhones to record in 4K.
High definition video (prerecorded and broadcast) is defined threefold, by: The number of lines in the vertical display resolution. High-definition television (HDTV) resolution is 1,080 or 720 lines. In contrast, regular digital television (DTV) is 480 lines (upon which NTSC is based, 480 visible scanlines out of 525) or 576 lines (upon which ...
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD (7680 × 4320) is the highest resolution defined in the Rec. 2020 (UHDTV) standard. [1] 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017.
The main advantage of recording video at the 4K standard is that fine spatial detail is resolved well. [146] Individual still frames extracted from 3840×2160-pixel video footage can act as 8.3 megapixel still photographs, while only 2.1 megapixels at 1080p and 0.9 megapixels at 720p.
Frame rate, most commonly expressed in frames per second or FPS, is typically the frequency (rate) at which consecutive images (frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with frame frequency and ...
The PXW-Z100 is a 7 lbs handheld camcorder with an integrated 20x 4K-compatible zoom lens. The PXW-Z100 is the first "prosumer" camera that uses Sony's XAVC recording format. MPEG-4 AVC/H.264 compression is used for HD (1920×1080), QFHD (3840×2160) and 4K (4096×2160) content. Image sampling is 4:2:2 10-bit, with an intra-frame system that ...
