4About it
A QR reader only looks at the middle of each square. Video QR keeps that middle dark or light for the code and paints the rest of each square from the video, the way Picture QR does, frame by frame. Every frame uses the same code, so it scans while it plays, not only when it stops.
The sample is six seconds of Big Buck Bunny by the Blender Foundation (CC BY 3.0). Your own video stays on this device.
