This sample shows how to play synchronized video clips in your DirectRT session. On each trial another video is added until on the fourth trial, four videos play in synch--one in each quadrant of the screen. For simplicity, the sample uses the same clip (video1.mpg) in all quadrants. You can, of course, substitute other videos and/or animations in the input file. Just place them in your stim folder and indicate the correct size when you list them in your input file. Note the colour.txt file contains 32 (for 32 bit colour). You might have to change that to 16 or 24 if your system doesn't support 32-bit color at 1024x768.
