AviSynth
AviSynth is a frameserver program for Microsoft Windows, Linux and macOS initially developed by Ben Rudiak-Gould, Edwin van Eggelen, Klaus Post, Richard Berg and Ian Brabham in May 2000 and later picked up and maintained by the open source community which is still active nowadays. It is free software under GNU GPL license. Scripting video editor AviSynth acts as a non-linear video editor controlled entirely by scripting (without a GUI). It emulates an AVI video file (or WAV audio file) as seen by the VFW downstream application, which is typically a media player, video editing software, or an encoder. AviSynth is built upon ''filters'', which are much like DirectShow filters, but with a different binary interface. Filter capabilities include cropping, deinterlacing, inverse telecine, working with still images, doing basic color grading, reducing video noise, and many other things. AviSynth also performs traditional video editing tasks like cutting, trimming and re-sequenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frameserver
A Frameserver is any program that acts as a media source in the process called ''frameserving'', which transfers digital video data from one computer program to another without intermediate files. The program that receives the data – the ''frameclient'' – could be any type of video application. The process is controlled by the frameclient: the frameclient ''requests'' audio/video frames and the frameserver ''serves'' them. The client can request frames in any order, allowing it to pause or jump to an arbitrary frame, just as a media player does with a file on disk. The client is most commonly a media encoder, a non-linear editing system, or a media player. Some popular frameservers are: * AviSynth * VirtualDub * Blender * Debugmode FrameServer See also Client–Server Model The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clien ...

Doom9
Doom9 is a website featuring information on digital audio and video manipulation (mostly video) and digital copyrights. It is also the forum username of the author of the page, an Austrian who was a college student at the time of the creation of the site. The site's tagline is "The Definitive DVD Backup Resource". Started in March 2000, the site has expanded to contain a wide range of information on the subject of digital video encoding and DVD backup (or ripping). The most popular sections of the site were the guides to DVD ripping and the annual codec comparisons, where popular digital video codecs were compared on the basis of quality, speed, and compression. The forum is frequented by many developers of the tools and codecs featured on the site, such as FairUse4WM. The VirtualDubMod project began after many modifications to VirtualDub were posted on the Doom9 forums. Doom9 gained notoriety as a result of its involvement in the AACS encryption key controversy.

Video Editing Software
Video editing software, or a video editor is software used performing the post-production video editing of digital video sequences on a non-linear editing system. It has replaced traditional flatbed celluloid film editing tools and analog video tape-to-tape online editing machines. Video editing software serves a lot of purposes, such as filmmaking, audio commentary, and general editing of video content. In NLE software, the user manipulates sections of video, images, and audio on a sequence. These clips can be trimmed, cut, and manipulated in many different ways. When editing is finished, the user exports the sequence as a video file. Components Timeline NLE software is typically based on a timeline interface where sections moving image video recordings, known as clips, are laid out in sequence and played back. The NLE offers a range of tools for trimming, splicing, cutting and arranging clips across the timeline. Another kind of clip is a text clip, used to add text to a v ...

Filter Graph
A filter graph is used in multimedia processing - for example, to capture video from a webcam. Filters take input, process it (or change the input), and then output the processed data. For example: a video codec takes raw uncompressed video and compresses it using a video standard such as H.264. To compress a multimedia stream a filter graph could have two inputs: # Audio # Video Usually these are expressed as file sources. The file sources would feed compression filters, the output of the compression filters would feed into a multiplexer that would combine the two inputs and produce a single output. (An example of a multiplexer would be an MPEG transport stream creator.) Finally the multiplexer output feeds into a file sink, which would create a file from the output.

Pixels
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although '' sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Windows Media Player
Windows Media Player (WMP) is the first media player and media library application that was developed by Microsoft for playing audio, video and viewing images on personal computers running the Microsoft Windows operating system, as well as on Pocket PC and Windows Mobile-based devices. Editions of Windows Media Player were also released for classic Mac OS, and Solaris but development of these has since been discontinued. Windows Media Player was eventually replaced in Windows 8 with Groove Music. Groove Music persisted in Windows 8.1 and Windows 10, before being replaced in turn with the Media Player in Windows 11. In addition to being a media player, the application has the ability to rip audio file from and copy to compact discs, burn recordable discs in Audio CD format or as data discs with playlists such as an MP3 CD, synchronize content with a digital audio player (MP3 player) or other mobile devices, and enable users to purchase or rent music from a number of onli ...
