I was thinking about applications like
https://developer.mozilla.org/samples/video/chroma-key/index.xhtml
( https://developer.mozilla.org/En/Manipulating_video_using_canvas )

Now it is using setTimeout so if processor is fast it will be
processing same frame more than on time. Hence wasting system
resource, which may affect other running process.

If we use timeupdate event we may be missing some frames as timeupdate
event is only happen every 200ms or 250ms, ie 4 or 5 frames per
second. And we know there are videos which a have more than 5 frames
per second.

Another Idea is to make timeupdate event frequency adjustable by Webdeveloper.

Thanks
