Tool Open source
AVAL is an open-source web format and runtime for short prerendered motion with continuous loops, named application states, authored triggers, bounded transitions, reversals, frame-accurate timing, and packed-alpha transparency. It packages a logical animation as codec-specific .avl files containing motion units and a state graph; the browser selects a decodable candidate from an AV1, VP9, H.265/HEVC, and H.264 ladder, while graph routes handle state changes rather than timestamp seeking. Projects are compiled from a motion.json file with the @pixel-point/aval-compiler package, producing a directory containing the .avl output and build metadata. AVAL requires the integrating application to handle unsupported browsers and fatal playback errors and does not itself create or reveal fallback video, image, text, or other content.

A web-video format that packages decodable motion units and a state graph in an .avl file. It lets browsers handle hover and state changes through graph routes rather than timestamp seeking, with alpha transparency and an image fallback.
