If it was a problem with the stimulus loading, wouldn’t the fixation cross for trial 2 show up before going blank? The movies were in gif format but were converted to H.264 mp4s when I got the same error as this person did in this thread.
Each mp4 file is ~69 KB
Regarding trialCount, this code worked before when “trialCount=0” was in the Begin Experiment code component for fixation…but now when moved to instr (outside of the loop) it’s getting this error- should I move it back?
