What is a AVS File Type?

The AviSynth software is distributed as a .DLL file, which acts as a "frameserver" that serves video frames to the media player on-demand when an AVS file is opened. In this manner, the media player recognizes the served frames as standard .AVI video data. Therefore, to play video using Avisynth, create an Avisynth script and then open it with a supporting AVI media player.
