Time-lapsed video in psychopy builder

Hello,
I use Psychopy Builder v2023.2.3 on W10 and i would like to play multiple video thanks to a loop and a condition files where the location of the video are strored (see condition_movie.png).
My videos in my main program (see Quest1904_obs) are played in fast forward and i don’t know why.
I haven’t this problem with a simple and testing program (Quest1904_test), yet it’s the same configuration (configuration of the loop and in the movie stimuli).
Any idea?
Thanks!
