Shih-Yu, As far as I know there is no way to directly export your stimuli to a quicktime movie. However, you can export each frame to an image using p.export_movie_go(), and then reconstruct a movie from those frames using your preferred software (e.g. Quicktime Pro). VisionEgg comes with two files in the demos folder, makeMovie.py and makeMovie2.py, which explain how to export frames using two different methods. Good luck!
