OS: Mac OS Mavericks, Win10
PsychoPy version** (e.g. 1.85.0):
Standard Standalone? yes.
What I am trying to achieve:
I want to show each participant a 15-minute movie and record multiple responses from them while it plays (which keys were pressed, and when). Ideally the timing would be from each of a number of set points in the video, but I would be content with having all of the response times measured from the beginning of the video. Any suggestions/help gratefully received!
