Hi all,
I’ve designed an experiment that loops through a set of videos and questions that need to be answered after each video. I’m running into the issue that there is an echo in the audio (not the video) at the end of each video --about half a second of the last bit of audio is repeated. I’ve googled this question but did not find a post that answered this question.
I’m using Psychopy version 2021.2.3 and Python 3.8 on macOS version 10.15.7. I use .mp4 video files, but also tried .mov and .m4v format, which did not solve the issue. Below an example of my code:
for clip in clips:
mov = visual.MovieStim3(win, clip, size=(1280, 720),
flipVert=False, flipHoriz=False, loop=False)
globalClock = core.Clock()
movie_stimuli3.append(mov)
for mov, questions_clip, clip in zip(movie_stimuli3, questions, clips):
d = visual.TextStim(win, " + ", pos=(0,50), height=50, wrapWidth=1300, units= 'pix')
d.draw()
win.flip()
time.sleep(0.5)
while mov.status != constants.FINISHED:
mov.draw()
win.flip()
win.flip()
Anyone an idea where this issue comes from or how to trouble shoot?
Thanks very much!
