![]() ![]() In 2014, the OnePlus One phone was published with a camera that is capable of recording DCI 4K at 24 fps. Among those cell phones, there was Samsung Galaxy Note 3, which can record 2160p at 30 frames per second (FPS). In late 2013, the first smartphones that can be recorded at 3480 x 2160p were released. High-efficiency video coding ( HEVC or H.265) should allow streaming of 4k videos with a bandwidth of 20 – 30 Mbit/s. 4K content on Vimeo is limited to mostly nature documentaries and tech coverage. Since 2010, YouTube and Vimeo permit a maximum upload resolution of 4096 x 3072 pixels, 12.6 megapixels, aspect ratio of 4:3. New utilities are added into UHD-1 Phase 2 like HDR using hybrid log-gamma (HLG) and perceptual quantizer (PQ) at 10 or 12 bits, high frame rate (HFR) up to 120Hz, as well as a wide color gamut. In 2016, DVB finalized UHD-1 Phase 2 together with the introduction of service by broadcasters expected in 2017. Dubbed DVB-UHDTV, it builds 2 standards called UHD-1 and UHD-2 with the former for 4K content and the latter for 8K. In 2014, the Digital Video Broadcasting Project published a new set of standards intended to lead the implementation of high-resolution content in broadcast television. That standard would also include framerates of up to 120Hz, high-efficiency video coding (HEVC) encoding, high dynamic range (HDR), and a wide color gamut. On March 26, 2013, the Advanced Television Systems Committee announced new proposals for a new standard named ATSC 3.0 that would implement UHD broadcasts at resolutions of up to 3840 x 2160 or 7680 x 4320. Advanced Television Systems Committee (ATSC) Compared with offline fields like TV shows and broadcasting, 4K content has become more widely available online on YouTube, Apple TV, Netflix, Hulu, Amazon, etc. The TV industry has adopted 3840 x 2160 as their 4K standard. The following are some common 4k footages and non-standardized 4K resolutions accepted by different industry niches. Whereas, the movie projection industry makes use of 4096 x 2160 p, DCI (digital cinema initiatives) 4K. Yet, the domain 4K standard is 3840 x 2160 p, which is also known as 4K UHD (ultra-high-definition television). Usually, digital television (TV) and digital cinematography take advantage of several different 4k resolutions. Learn more details below!
