Re : Show videos with processing

you should probably find out the length of the first movie  http://processing.org/reference/libraries/video/Movie_duration_.html then compare it with how much time has elapsed since the first movie started playing, when those values match (or whatever relevent condition that you determine is met) start playing the next video. I'd suggest just testing this with two of the video's before moving on to include a third one. This can be achieved with a conditional. here's a helpful thread on setting up a timer in processing http://forum.processing.org/topic/timer-in-processing Also worth noting that if you are not fammiliar with using conditionals the processing reference and ascociated link on that page are good resources to help you get started http://processing.org/reference/if.html
