An AVS file most commonly functions as a script for AviSynth/AviSynth+ defining how to load and process video—resizing, cropping, trimming, deinterlacing, denoising, sharpening, frame-rate changes, or adding subtitles—which you open either in a text editor or in VirtualDub2/AvsPmod to run and preview before encoding via ffmpeg or similar tools; readable commands like LoadPlugin, plus tiny filesize, identify it as AviSynth, while preview issues usually come from missing filters, nonexistent file paths, or version mismatches, though in some contexts "AVS" instead refers to other programs’ config/project files that don’t behave like AviSynth scripts.

An AVS file is sometimes a saved project from AVS Video Editor, meaning it stores the structure of your edit—timeline layout, imported clips, trims, splits, transitions, titles, effects, audio changes, and export settings—so it’s small because it holds references rather than actual video, which is why it won’t play in VLC or look meaningful in Notepad and must be opened inside AVS Video Editor, where missing clips appear if source files were moved or removed, and sharing the project requires copying both the AVS file and all referenced media in the same folder structure.

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.

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.
