An AVS file is widely recognized as an AviSynth/AviSynth+ text script that defines how to load and process video—resizing, trimming, cropping, deinterlacing, denoising, sharpening, frame-rate conversion, or subtitle insertion—and isn’t a standalone video; you open it either in a text editor to inspect commands or in a tool like VirtualDub2/AvsPmod to execute the script and preview results, usually feeding that into an encoder afterward, and you can recognize AviSynth scripts by readable commands such as Crop, plus small file size, while failures typically point to missing plugins, wrong file paths, or version mismatches, though some unrelated apps also use "AVS" for their own non-AviSynth configs that require the original program.

An AVS file can act as an AVS Video Editor project file, holding your editing layout—clip placements, trims, transitions, effects, titles, audio tweaks, and output settings—making it much smaller than the actual footage since it stores references, not media, so regular players can’t open it and Notepad displays confusing data, and it must be loaded through AVS Video Editor, where missing-source warnings appear if files were renamed or moved, and transferring the project requires copying the AVS file plus all original media with matching folder paths.

When I say an AVS file is normally a video script/project, I mean it doesn’t store real audio/video data but instead holds instructions that a program interprets to build the video output; the usual form is an AviSynth script: a simple text file describing operations like trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate conversion, or adding subtitles, while other programs use AVS as a project file containing timelines and references, which is why AVS files are small, unplayable in standard players, and must be opened as text or inside the correct editing application.

What appears inside an AVS varies by creator, but for AviSynth it’s a set of human-readable instructions forming a pipeline: the script begins by calling a source filter to load the video file, may load plugin DLLs, and then performs operations like trim cuts, edge cropping, resolution resizing, deinterlacing, noise reduction, sharpening, frame-rate adjustments, color/levels edits, or subtitle insertion, with every line serving a functional step, and common errors like "no function named …" or "couldn’t open file" typically point to missing filters or incorrect file paths.
