A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9 ) alongside ...

A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .
ffdshow (wraps libavcodec as a DirectShow filter and adds postprocessing to improve image quality; once installed, it is automatically used by all Windows DirectShow video players, such as Windows Media Player, Media Player Classic, Winamp etc. It also wraps libavcodec as a Video for Windows filter; the framework used by most video editing ...
Resource Interchange File Format (RIFF) is a generic file container format for storing data in tagged chunks. [2] It is primarily used for audio and video, though it can be used for arbitrary data. [3] The Microsoft implementation is mostly known through container formats like AVI, ANI and WAV, which use RIFF as their basis. [4]
File formats often have a published specification describing the encoding method and enabling testing of program intended functionality. Not all formats have freely available specification documents, partly because some developers view their specification documents as trade secrets, and partly because other developers never author a formal specification document, letting precedent set by other ...
Some filenames are given extensions longer than three characters. While MS-DOS and NT always treat the suffix after the last period in a file's name as its extension, in UNIX-like systems, the final period does not necessarily mean that the text after the last period is the file's extension. [1]
A binary file is a computer file that is not a text file. [1] The term "binary file" is often used as a term meaning "non-text file". [ 2 ] Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text , such as older Microsoft Word document files, contain the text of ...
