Comparison Of Video Converters
Video converters are computer programs that can change the storage format of digital video. They may recompress the video to another format in a process called transcoding, or may simply change the container format without changing the video format. The disadvantages to transcoding are that there is quality loss when transcoding between lossy compression formats, and that the process is highly CPU intensive. This article compares video converters that have their own article on Wikipedia.

Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. ( Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for execution, ...

MPEG Program Stream
Program stream (PS or MPEG-PS) is a container format for multiplexing digital audio, video and more. The PS format is specified in MPEG-1 Part 1 (ISO/IEC 11172-1) and MPEG-2 Part 1, Systems (ISO/IEC standard 13818-1/ITU-T H.222.0). The MPEG-2 Program Stream is analogous and similar to ISO/IEC 11172 Systems layer and it is forward compatible.ISO (2000-12-01ISO/IEC 13818-1 : 2000, Second editionPage X, Retrieved on 2009-07-25 Program streams are used on DVD-Video discs and HD DVD video discs, but with some restrictions and extensions.DVD - MPeg differences Retrieved on 2009-07-24 The filename extensions are VOB and EVO respectively.

MPEG-4 Part 14
MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only filename extension for MPEG-4 Part 14 files as defined by the specification is .mp4. MPEG-4 Part 14 (formally ISO/IEC 14496-14:2003) is a standard specified as a part of MPEG-4. Portable media players are sometimes advertised as "MP4 players", although some are simply MP3 players that also play AMV video or some other video format, and do not necessarily play the MPEG-4 Part 14 format. History MPEG-4 Part 14 is an instance of the more general ISO/IEC 14496-12:2004 (MPEG-4 Part 12: ISO base media file format) which is directly based upon the QuickTime File Format which was published in 2001. MPEG-4 Part 14 is essentially identical to the QuickTime File Format, but formally specifies support for Initial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matroska
Matroska is a project to create a container format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. The Matroska Multimedia Container is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is an open standard. Matroska file extensions are ''.mkv'' for video (which may include subtitles or audio), ''.mk3d'' for stereoscopic video, ''.mka'' for audio-only files (which may include subtitles), and ''.mks'' for subtitles only. History The project was announced on 6 December 2002 as a fork of the Multimedia Container Format (MCF), after disagreements between MCF lead developer Lasse Kärkkäinen and soon-to-be Matroska founder Steve Lhomme about the use of the Extensible Binary Meta Language (EBML) instead of a binary format. This coincided with a 6-month coding break by the MCF's lead developer for his military service, during which most of the community quickly migrated to the new project. In ...

DVD Video
DVD-Video is a consumer video format used to store digital video on DVD discs. DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on November 1, 1996 (with major releases beginning December 20, 1996), followed by a release on March 24, 1997 in the United States—to line up with the 69th Academy Awards that same day. The DVD-Video specification was created by DVD Forum and can be obtained from DVD Form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2TS
.m2ts is a filename extension used for the Blu-ray disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container.Blu-ray Disc Association (March 2005BD ROM – Audio Visual Application Format Specifications(PDF) Page 15, Retrieved on 2009-07-26Archived2009-07-29.AfterDawn.coGlossary – BD-MV (Blu-ray Disc Movie) and BDAV container Retrieved on 2009-07-26Archived2009-07-29.AfterDawn.coGlossary – BDAV container Retrieved on 2009-07-26 This container format is commonly used for high definition video on Blu-ray Disc and AVCHD. Overview The BDAV container format is a modification of the MPEG-2 transport stream (ITU-T H.222.0 , ISO/IEC 13818-1) specification for random-access media, such as Blu-ray discs, DVDs, hard drives or solid-state memory cards. The format is informally called ''M2TS''. In order to optimize the storage size, the format uses vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Video Interleave
Audio Video Interleave (also Audio Video Interleaved and known by its initials and filename extension AVI, usually pronounced ), is a proprietary multimedia container format and Windows standard introduced by Microsoft in November 1992 as part of its Video for Windows software. AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used. Many AVI files use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called "AVI 2.0". In 2010 the US government's National Archives and Records Administration defined AVI as the official wrapper for preserving digital video. History Publishers faced a predicament regarding how they should distribute videos on CD-ROMs. Thirty seconds of video displayed in 24-bit color an ...

Comparison Of Container Formats
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural activity, which even animals engage in when deci ...

VirtualDub
VirtualDub is a free and open-source video capture and video processing utility for Microsoft Windows written by Avery Lee. It is designed to process linear video streams, including filtering and recompression. It uses AVI container format to store captured video. The first version of VirtualDub, written for Windows 95, to be released on SourceForge was uploaded on August 20, 2000. In 2009, the third-party software print guide ''Learning VirtualDub'' referred to VirtualDub as "the leading free Open Source video capture and processing tool". Due to its "powerful" versatility and usefulness especially in the field of video processing (see below), ''PC World'' has referred to VirtualDub as "something of a 'Photoshop' for video files", ''PC Perspective'' recommends it for its low overhead, and nextmedia's ''PC & Tech Authority'' particularly praises it for its ''Direct stream copy'' feature to avoid generational degradation of video quality when performing simple editing and tri ...
