This test checks if your browser correctly renders H.264 encoded video frames with full range and limited range BT.709 colour space.

It renders 192 by 192 pixel squares and a video into the middle of each square. Each video contains a different 16 by 16 pixel frame that should match the colour of the square onto which it is drawn. The frames are scaled up by 4 for easier viewing.

All videos have the colour space and the range coded into the bit stream. The browser should pick up the colour information from the bit stream and render it correctly.

If the browser doesn't render the videos correctly, you'll see a faint square inside one or more of the squares.
