Demos

Demo 0.1

When the Play button is pressed on the video the frames from that video will be written to a number of canvases. The first canvas is just a straight frame by frame copy of the video. The second canvas is trying to mimic a comic book style by modifying frames to create solid colours. The last row of canvases are having the video frames written to them with offsets to give the effect of a moving video.

The video time is being tracked which will eventually be used to execute javascript at time intervals.

Demo 0.2

This demo combines the close pixelate library with video and canvas.

Demo 0.3

An optimized version using a back buffering technique.

Current Issues

• I've combined the close pixelate library together with video but it's quite choppy. This is probably because of the amount processing required to render the effect.
