First i want to say thanks for this great plugin.
I mean the frame of the video.
Here's my test:
http://db.tt/G2zvWyWU (There are 4 videos. May take a long time to load)
Because of Z-Order didn't worked I tried this solution. I rendered first and last frame as a image. After the end of the video i moved the video to negative coordinates. And call the last frame as an image. The coordinates of the image and video seems fine on C2 but they're moving a fex pixels in browser.
