  1. 01

    Import

    Open local media. Studio inspects timing, dimensions, codec, transparency, and source-prep requirements.

  2. 02

    Author

    Define states, units, routes, triggers, loops, reversals, and exact half-open frame ranges.

  3. 03

    Build

    Compile AV1, VP9, H.265, and H.264 assets with the official AVAL compiler.

The .avl file format is the foundation.

AVAL was created and open-sourced by Pixel Point.

AVAL packages prerendered motion, named application states, authored triggers, bounded transitions, reversals, and packed transparency for the web.

.avl

Interactive video as a real file type.

One logical animation is published as an ordered codec bundle. Every rendition carries the same state graph and authored timing, so the browser can choose AV1, VP9, H.265, or H.264 without changing behavior.

Media type

Current format
AVAL 1.0

Frame-accurate timeline

Author with exact half-open frame ranges and precise state transitions.

Interactive state preview

Scrub, step, and inspect states and routes with instant feedback.

Packed-alpha workflow

Prepare and validate transparency for reliable browser playback.

Local-first desktop

Source media stays on your machine. No upload is required.

Reproducible builds

Compiler, Node runtime, and media-tool provenance are pinned and recorded.

No competing encoder

Uses the official AVAL compiler for encoding and browser-ready bundles.

Built in the open, with the AVAL community.

AVAL Design Studio is an independent MIT-licensed companion to AVAL. Designers, animators, web developers, codec experts, and accessibility advocates can help make authoring easier while the official AVAL compiler remains the authority for every final bundle.
