An AVS file is typically an AviSynth/AviSynth+ text script that acts like a plain-text "recipe" for loading and processing video—trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate changes, or subtitles—rather than being actual media like MP4/MKV/AVI, and you can open it either in a text editor to read/edit commands or in a compatible video tool (VirtualDub2 or AvsPmod) to execute and preview the result before encoding via ffmpeg or similar tools; readable commands such as FFVideoSource, along with typically tiny file size, confirm it’s AviSynth, and preview failures usually come from missing plugins, bad paths, or version mismatches, though "AVS" can also refer to config/project files from other programs that must be opened in the software that created them.

An AVS file can function as an AVS Video Editor project file, storing your timeline design—clip positions, splits, trims, transitions, overlays, effects, and audio settings—so it stays small since it only references media, meaning VLC or Notepad can’t interpret it, and the correct way to open it is through AVS Video Editor, which may report missing files if originals were relocated, while sharing or moving the project requires copying the AVS file plus all the referenced footage in the same folder arrangement.

When I say an AVS file is usually a video script/project format, I mean it doesn’t embed the video/audio like MP4/MKV but instead carries instructions or a blueprint that a program follows to produce the video, most commonly as an AviSynth text script describing how to load footage and perform tasks such as trimming, cropping, resizing, deinterlacing, denoising, sharpening, changing frame rate, or adding subtitles, while in other situations an AVS is a project file from an editor storing timeline info and references to your clips, which explains why AVS files are small, unplayable in standard players, and must be opened either as plain text or inside the correct editing program.

The content of an AVS varies, but for AviSynth it’s a set of ordered, text-based commands describing how to process video: it begins with a source-loading function referencing a file on disk, may include plugin loads, and applies processing steps—trims, crops, resizes, deinterlaces, denoises, sharpens, adjusts frame rate or levels, and adds subtitles—each line specifying some load or transformation, and if the script references a missing plugin or incorrect path you’ll see errors like "no function named …" or "couldn’t open file."
