Robert O'Callahan has been posting about his 'bling branch' which contains some very nice effects. See his blog posts for more detail:
As soon as I saw these I had to try the effects with a playing video. The video patches apply fine to the svg-integration branch.
The screencast below is from this special build, displaying a video played using <video>. There is a reflection below it using the tricks from Robert's posts. Shortly after that I change to a video playing that uses an SVG filter for edge detection when I mouse over the video. Finally there is a video with both effects combined.
