Thanks for your link.
I opened it up and examined it around.
But couldn’t find any hint for present image and movie simultaneously.
I’m trying to present an black image with symbols (800x600) and quicktime movie(50x50) simultaneously. (the position of movie is middle of image)
Following the experiment you’ve attached, the image always presented slightly before the movie.
If technically,It is impossible to present both simultaneously, I have to re-render the bigger(800x600) movies containing the symbols.
thanks always. : )
