Compressor (software)
Compressor is a video and audio media compression and encoding application for use with Final Cut Studio and Logic Studio on macOS. It can be used with Qmaster for clustering, or configured as a server to work on the jobs submitted by other computers on the network. History The application used to be available as part of Final Cut Pro, Soundtrack Pro, Motion, and DVD Studio Pro, and after Apple combined its professional media products into Final Cut Studio and Logic Studio bundles, Compressor became available as part of them. Once the bundle model was abandoned by Apple in 2011, a new major version of Compressor (Compressor 4) was released as a separate product on the Mac App Store for $49.99. Features Compressor is used for encoding video and audio media in multiple formats, including HEVC (H.265), MPEG-1, MPEG-2 for DVD, QuickTime .mov, MPEG-4 (Simple Profile), MPEG-4 H.264 and optional (third Party and often commercial) QuickTime Exporter Components to export to Windo ...

Apple Inc
Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, as of June 2022, is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user inte ...

Soundtrack Pro
Soundtrack Pro is a discontinued music composing and audio editing application made by Apple Inc. featured in Logic Studio and Final Cut Studio that included a collection of just over 5,000 royalty free professional instrument loops and sound effects. It was discontinued with the release of Final Cut Pro X, Motion 5, and Compressor 4. History An earlier incarnation of the package, Soundtrack, was first sold as part of Apple's Final Cut Pro 4 video editor, released in April 2003. It was then released as a stand-alone product, but due to low demand it was discontinued. The main concept of Soundtrack was to allow people who are not professional composers to produce original music for their videos or DVDs, royalty-free. The music could be easily scored to QuickTime movies and Final Cut Pro projects. Soundtrack was reinstated in January 2005 as part of Final Cut Express HD. Soundtrack ''Pro'' was introduced on April 17, 2005 as a stand-alone product and as part of the Final Cut S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Reduction
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio. All signal processing devices, both analog and digital, have traits that make them susceptible to noise. Noise can be random with an even frequency distribution (white noise), or frequency-dependent noise introduced by a device's mechanism or signal processing algorithms. In electronic systems, a major type of noise is ''hiss'' created by random electron motion due to thermal agitation. These agitated electrons rapidly add and subtract from the output signal and thus create detectable noise. In the case of photographic film and magnetic tape, noise (both visible and audible) is introduced due to the grain structure of the medium. In photog ...

High-definition Video
High-definition video (HD video) is video of higher resolution and quality than standard-definition. While there is no standardized meaning for ''high-definition'', generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. 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. History The first electronic scanning format, 405 lines, was the first ''high definition'' television system, since the mechanical systems it replaced had far fewer. From 1939, Europe and the US tried 605 and 441 lines until, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard-definition Video
Standard-definition television (SDTV, SD, often shortened to standard definition) is a television system which uses a resolution that is not considered to be either high or enhanced definition. "Standard" refers to it being the prevailing specification for broadcast (and later, cable) television in the mid- to late-20th century, and compatible with legacy analog broadcast systems. The two common SDTV signal types are 576i, with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems, and 480i based on the American NTSC system. Common SDTV refresh rates are 25, 29.97 and 30 frames per second. Both systems use a 4:3 aspect ratio. Standards that support digital SDTV broadcast include DVB, ATSC, and ISDB. The last two were originally developed for HDTV, but are also used for their ability to deliver multiple SD video and audio streams via multiplexing. In North America, digital SDTV is broadcast in the same 4:3 aspect ratio as NTS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NTSC
The first American standard for analog television broadcast was developed by National Television System Committee (NTSC)National Television System Committee (1951–1953), Report and Reports of Panel No. 11, 11-A, 12–19, with Some supplementary references cited in the Reports, and the Petition for adoption of transmission standards for color television before the Federal Communications Commission, n.p., 1953], 17 v. illus., diagrs., tables. 28 cm. LC Control No.:5402138Library of Congress Online Catalog/ref> in 1941. In 1961, it was assigned the designation CCIR System M, System M. In 1953, a second NTSC standard was adopted, which allowed for color television broadcast compatible with the existing stock of black-and-white receivers. It is one of three major color formats for analog television, the others being PAL and SECAM. NTSC color is usually associated with the System M. The only other broadcast television system to use NTSC color was the System J. Since the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG-2
MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard. Main characteristics MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar discs. TV stations, TV receivers, DVD players, and other equipment are ...

High Efficiency Video Coding
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses integer DCT and DST transforms with varied block sizes between 4×4 and 32×32. The High Efficiency Image Format (HEIF) is based on HEVC. , HEVC is used by 43% of video developers, and is the second most widely used video coding format after AVC. Concept In most ways, HEVC is an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DVD Studio Pro
DVD Studio Pro is a discontinued high-end software tool published by Apple Inc. to allow users to create DVD masters to be sent out for replication at production houses. Its tight integration with other Apple applications allowed users to take Final Cut Pro and Motion projects and render them into the DVD format without encoding to intermediary formats. History Apple bought Astarte's DVDirector in 2000, re-releasing it as DVD Studio Pro in 2001. Version 1.5, still based on this original code, was released in April 2002. In the meantime Apple had acquired Spruce Technologies in 2001, and was retooling the DVD authoring package that came with that acquisition (DVD Maestro). In August 2003, Apple released DVD Studio Pro 2, with a new interface. DVD Studio Pro 3 was released in 2004. In April 2005, Apple updated DVD Studio Pro to support authoring HD content.
