An AVS file serves primarily as a plain-text AviSynth command list that describes video-loading and processing steps—cutting, cropping, resizing, deinterlacing, denoising, sharpening, frame adjustments, and subtitle handling—rather than storing media itself, and you can open it either as text or inside tools like VirtualDub2 or AvsPmod to run and preview it before encoding through ffmpeg or other software; recognizable commands such as AVISource and small size confirm it’s AviSynth, with preview errors usually due to missing filters, invalid paths, or version conflicts, while some programs also use "AVS" for their own project/config files that don’t resemble AviSynth scripts.

An AVS file may represent a project from the AVS4YOU suite, 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 mostly a video script or project file, I mean it doesn’t carry the raw footage like MP4/MKV but rather acts as a set of instructions a program uses to generate the processed video, often as an AviSynth script that lists tasks such as trimming, cropping, resizing, deinterlacing, denoising, sharpening, adjusting frame rates, or inserting subtitles, or as an editor project that saves only timeline edits and media references, explaining why AVS files are tiny, won’t play directly, and must be opened as text or inside the originating software.

The contents of an AVS depend on the software, but in the AviSynth case it’s a text script made of sequential commands: it first loads the video source using a dedicated source function, optionally loads additional filters via plugin calls, and then applies edits—trimming start/end frames, cropping borders, resizing to target dimensions, deinterlacing, cleaning noise, sharpening details, adjusting frame rate or colors, and overlaying subtitles—so each statement modifies or prepares the stream, and errors such as "no function named …" or "couldn’t open file" usually indicate missing plugins or wrong paths.
