| − | === What is AviSynth? === __NOEDITSECTION__
| + | |
| − | *It is a '''powerful tool for video post-production.''' It provides ways of editing and processing videos.
| + | |
| − | *It is a '''[[frameserver]]''' to your other video programs, providing instant editing without the need for temporary files.
| + | |
| − | *It is a '''script system''' for '''[[Filter|video filters]]''' and '''advanced non-linear editing'''.
| + | |
| − | <p style="margin-left:1em;">
| + | |
| − | It's called ''AviSynth'' because it ''synthesizes'' a virtual [[wikipedia:Audio_Video_Interleave|''Avi'']] file, "[[Original_AviSynth_announcement|generating]] video and audio data according to the script and feeding it to the application as needed." It is much '''more''' than that, though: to get an idea, take a quick glance at all the [[External_filters|third-party plugins]] available. At the same time, it is much '''less''': it's easy to [[Script_examples|create a quick script]] to solve some video problem.
| + | |
| − | </p>
| + | |
| − | <p style="margin-left:1em;">
| + | |
| − | AviSynth itself does not provide a graphical user interface (GUI). While scripting may at first seem tedious and unintuitive, it is '''remarkably powerful''' and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are '''human readable''', projects are inherently self-documenting. The scripting language is '''simple yet powerful''' - basic [[Filter|filters]] can be combined to create useful and unique effects.

| − | ** [http://www.doom9.org/capture/postprocessing_avisynth.html Analog Capture guide]. The AviSynth part of the capture guide is about what filters can be used to enhance the quality of the capture. It discusses things like deinterlacing, denoising, cropping and resizing and color adjustment. Which makes it really useful to learn about some of the capabilities of AviSynth in a schematic way.
