An AVS file commonly serves as a small AviSynth instruction file 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 LoadPlugin, 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 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 normally a video script/project, I mean it isn’t a standalone media file but instead holds instructions that a program interprets to build the video output; the usual form is an AviSynth script: a simple text file describing operations like trimming, cropping, resizing, deinterlacing, denoising, sharpening, frame-rate conversion, or adding subtitles, while other programs use AVS as a project file containing timelines and references, which is why AVS files are small, unplayable in standard players, and must be opened as text or inside the correct editing application.

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.
