Hi,
I have a big problem right now. My program includes two parts: video display and slider bar display.
A series of facial expressions will bedisplayed dynamically as short video clips. Each clip will last two seconds and disappear afterwards. After theclip, an intensity rating in three emotion categories (anger, disgust and fear)will be presented.
The format of the video is mov in mac and wmv in windows. The average size of the video is 160kb. The mac-version program can run quite fluently on mac, however, the win-version can not run fluently on win7. The programs are the same except for the format of the video.
The problem on win7 is that the start of the video and also the start of the slider bar lose frame. They become black at first and then show the stimuli.
Hope the following language will help you to understand my problem better. Hope to get the reply from you soon. Thanks!
