An AVS file is generally an AviSynth/AviSynth+ script that lays out how to load and transform video—cropping, trimming, resizing, deinterlacing, denoising, sharpening, frame-rate edits, or subtitle inclusion—so it’s not a playable video itself; it opens either in a text editor or in tools like VirtualDub2/AvsPmod to execute and preview, and common indicators include
readable commands like Import plus very small size, with errors usually tied to missing plugins, wrong source paths, or version mismatch, but "AVS" can also refer to unrelated config/project files from other apps requiring their specific software.

An AVS file is often used as a project blueprint in AVS Video Editor, 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 isn’t a self-contained video format 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.
What an AVS holds depends on who generated it, though an AviSynth script typically consists of readable lines that map out a processing workflow: the script loads the source video with a chosen input function, may load plugins to unlock specialized filters, then performs transforms like trimming, cropping, resizing, deinterlacing, denoising, sharpening, timing/frame-rate management, color corrections, or subtitle overlays, with every line contributing to the final rendered stream, and failures such as "no function named …" or "couldn’t open file" usually stem from absent plugins or invalid source locations.
