Videostrates is a web-based video substrate and toolkit that turns a web page into a live, editable video composition using HTML, CSS, WebGL shaders and custom elements, stored on Webstrates and streamed via a GStreamer-controlled headless Firefox. It enables real-time collaboration across independent editors (timeline, subtitles, notebooks), records and broadcasts live compositions, and handles up to six 4K sources to 720p on a consumer machine. Current limits: no audio, no WebRTC FEC, and server DoS risks.
