Serial digital interface (SDI) is a family of digital video interfaces first standardized by SMPTE in 1989. For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for broadcast-grade video. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s.
High-Definition Multimedia Interface (HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards.
HDV is a format for recording of high-definition video on DV videocassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
Avid DNxHD is a lossy high-definition video post-production codec developed by Avid for multi-generation compositing with reduced storage and bandwidth requirements. It is an implementation of SMPTE VC-3 standard.
A motion picture film scanner is a device used in digital filmmaking to scan original film for storage as high-resolution digital intermediate files.
Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a digital video stream, or more often, simply video stream. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both.
A video router, also known as a video matrix switch or SDI router, is an electronic switch designed to route video signals from multiple input sources such as cameras, VT/DDR, computers and DVD players, to one or more display devices, such as monitors, projectors, and TVs.
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, and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI. Standards also exist for the carriage of uncompressed video over computer networks.
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD is the highest resolution defined in the Rec. 2020 (UHDTV) standard.
Doremi Laboratories, Inc., often shortened to Doremi Labs, was a developer and manufacturer of digital servers and format converters for the digital cinema, broadcast, post-production and professional A/V markets. It was established in 1985 in Burbank, California, United States, and was absorbed into Dolby Laboratories in a 2014 acquisition.
XAVC is a recording format that was introduced by Sony on October 30, 2012. XAVC is a format that will be licensed to companies that want to make XAVC products.
Apple ProRes is a high quality, "visually lossless" lossy video compression format developed by Apple Inc. for use in post-production that supports video resolution up to 8K. It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. Much like the H.26x and MPEG standards, the ProRes family of codecs use compression algorithms based on the discrete cosine transform (DCT). ProRes is widely used as a final format delivery method for HD broadcast files in commercials, features, Blu-ray and streaming.
The hybrid log–gamma (HLG) transfer function is a transfer function jointly developed by the BBC and NHK for high dynamic range (HDR) display. It is backward compatible with the transfer function of SDR. It was approved as ARIB STD-B67 by the Association of Radio Industries and Businesses (ARIB). It is also defined in ATSC 3.0, Digital Video Broadcasting (DVB) UHD-1 Phase 2, and International Telecommunication Union (ITU) Rec. 2100.
The Blackmagic Cinema Camera is a digital movie camera developed and manufactured by Blackmagic Design and released on September 4, 2012. It is part of the Cinema Camera family of digital movie cameras and shoots 2.5K video in raw, Apple ProRes, CinemaDNG and Avid DNxHD formats.
The Blackmagic URSA is a digital movie camera developed and manufactured by Blackmagic Design, released on August 8, 2014. It is the first camera to be user-upgradeable for additional equipment manufactured by Blackmagic and other third-party makers.
10K resolution refers to a horizontal display resolutions of approximately 10,000 pixels. Unlike 4K UHD and 8K UHD, there are no 10K resolutions defined in the UHDTV broadcast standard. The first 10K displays demonstrated were ultrawide "21:9" screens with a resolution of 10240 × 4320, the same vertical resolution as 8K UHD.
DaVinci Resolve is a proprietary color grading, color correction, visual effects, and audio post-production video editing application for macOS, Windows, and Linux, developed by Australian company Blackmagic Design. It was originally developed by American company Da Vinci Systems under the name da Vinci Resolve until 2009, when Blackmagic Design acquired the company. In addition to the commercial version of the software, Blackmagic Design also distributes a free edition with reduced functionality, simply named DaVinci Resolve.
32K resolution refers to a display resolution of approximately 32,000 pixels horizontally. A resolution of 30720 × 17280 for an aspect ratio of 16:9 is speculated to be standardized. This doubles the pixel count of 16K in each dimension, for a total of 530.8 megapixels, 4 times as many pixels as the 16K resolution. It has 16 times as many pixels as 8K resolution, 64 times as many pixels as 4K resolution, 256 times the pixels as Full HD or 1080p resolution, and 576 times the pixels as HD or 720p resolution.
Atomos is an Australian company primarily engaged in manufacturing and distribution of video equipment. The company specializes in producing 4K and HD Apple ProRes monitor recorders, designed for various video production purposes, including social media, YouTube, television, and cinematography. Atomos has significantly contributed to the adoption of Apple ProRes RAW format in Cinema Cameras. The company has also made innovations in several areas, including RAW recording through HDMI, wireless timecode, multi-camera setups, asynchronous switching, and streaming solutions.
