Audio Video Interleave (also Audio Video Interleaved and known by its initials and filename extension AVI, usually pronounced / ˌ eɪ. v iː ˈ aɪ / [3]) is a proprietary multimedia container format and Windows standard [4] introduced by Microsoft in November 1992 as part of its Video for Windows software.
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.
Windows 11 is the latest major release of the Windows NT operating system and the successor of Windows 10. Some features of the operating system were removed in comparison to Windows 10, and further changes in older features have occurred within subsequent feature updates to Windows 11. Following is a list of these.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
It allows the user to specify a specific target file size. In the first pass, the encoder analyzes the input file and automatically calculates possible bitrate range and/or average bitrate. In the last pass, the encoder distributes the available bits among the entire video to achieve uniform quality. [10]
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 audio data in an audio coding format (e.g. Opus).
Overhead. This is the difference in file-size between two files with the same content in a different container. Support for advanced codec functionality. Older formats such as AVI do not support new codec features like B-frames, VBR audio or VFR video natively. The format may be "hacked" to add support, but this creates compatibility problems.
AviSource("myAvi.avi") Crop(0, 0, 320, 240) Blur(0.1) This script file can be opened in most media players (such as Windows Media Player). The program will play the video file "myAvi.avi" cropped down to its top-left 320 pixels by 240 pixels and blurred by a small amount. Operations occur in sequential order, so the cropping occurs first, then ...
