We have programed ttl into a 60 seconds videos stimuli. When we just run this individual questionnaire of video that contain the ttl, the recording computer gets the signal. But when we run the whole Experiment file, the ttl does not show. We program ttl: 255, location number, 60.
Is it because we should not program the time at 60seconds?
We actually just need to know when video is played, so should we change the time to shorter, say 3 seconds?
Thank you!
