An AVS file is most often used as an AviSynth/AviSynth+ instruction file 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 work as a non-media project file in AVS Video Editor, holding metadata such as clip imports, timeline positions, edit operations, transitions, titles, effects, and audio adjustments, making it tiny because it contains links, not full video, so it won’t play in standard players and appears confusing in text editors; it needs to be opened in AVS Video Editor, where missing media occurs if source files changed locations, and transferring the project means copying the AVS plus all media files with preserved folder paths.

When I say an AVS file is usually a video script or project file, I mean it is not storing the full footage itself but instead stores instructions—a kind of blueprint—that another program uses to generate the final output; the most common example is an AviSynth script, a tiny text file telling AviSynth how to load a source video and apply steps like trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate changes, or subtitles, while in other cases an AVS is a video-editor project that keeps timeline edits and media references, which is why AVS files are small, don’t play in normal players, and must be opened either as text (scripts) or inside the software that created them (projects).

What’s inside an AVS depends on its origin, but in the typical AviSynth sense it contains readable, code-like lines that outline a full video-processing chain: it starts by loading the source with a function pointing to an AVI/MP4/MKV, may load extra plugins, then applies steps like trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate handling, color tweaks, or subtitles, with each line either loading, transforming, or preparing the video for output, so errors such as “no function named …” or “couldn’t open file” usually indicate missing plugins or invalid paths.
