I have included the code below but all I have in the builder is the movie showing for 2s without any other components. I have a central presentation [0,0] and size [1,1] which seems to be quite large for my screen with other text or polygon components. All I need to do is present a movie for no more than 35 seconds but have participants guess when it has been playing for 10, 20, or 30s. I will have a single button response.
It really is simple!
