An AVS file commonly functions as a small AviSynth processing script that tells the system how to load and modify a video—crop, trim, resize, deinterlace, denoise, sharpen, adjust frame rate, or apply subtitles—so it’s not a video itself, and you can view it as text or run it in tools like VirtualDub2 or AvsPmod to preview output before encoding through ffmpeg or GUI encoders; typical clues include readable commands like Resize, plus small filesize, and errors usually stem from missing filters, invalid paths, or version issues, while some programs reuse "AVS" for their own config/project formats that only open inside the originating app.

An AVS file can also be a project file 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 typically a script or project file, I mean it isn’t meant to contain the actual footage but stores directions that another tool uses to reconstruct the final output, most often as an AviSynth script—a small text recipe that loads a source and runs operations like trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate adjustments, or subtitles—while other software uses AVS as a project format that saves timeline arrangements and references to media, which is why AVS files stay small and require either a text editor or the creating program to open properly.

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.
