If this template helps then use it. If not then just delete and start from scratch.

Standard Standalone? (y/n) If not then what?: Not Sure
What are you trying to achieve?:
My study is fairly straightforward. I am trying to build a program that presents trials of short video clips as stimuli, each followed by a keyboard response.
The video is of a boxer as seen from POV of participant, and the boxer throws a punch. The screen cuts to the response routine before it can be determined where the punch will go. Then they have 3 seconds to predict the location of the punch (left, right, or center), using the keyboard. Following their response, a different video will display and the cycle repeats.
There are 8 videos (conditions) that will be randomized 10 times for a total of 80 trials.
How do I create a loop that randomly (not full randomly) presents the 8 video routines, each followed by a keyboard response routine.
What I am really confused with is how to properly incorporate the Excel conditions and parameters into the builder so that PsychoPy knows the correct responses to the proper video.
What did you try to make it work?:
I could elaborate extensively on what I’ve tried to make this work and try to guess where I’ve gone wrong. But I think it would just be easier for a PsychoPy vet to walk me through the process of properly embedding video stimuli and creating the proper loop. I’m probably just a few adjustments off, but it could be that I botched the design from the start.
Any and all information is appreciated.
What specifically went wrong when you tried that?:
The following is a list of errors that pop up in lieu of the program actually running. I have no idea what this indicates. Errors:
