Dear Avisha,
I’m not that familiar with the movie component and why it’s not working correctly. However as a way to debug it, and maybe just use this option as the main timing method (for peace of mind), you can try creating a code component that sets a variable as true 1s into the trial routine. Then for the start time of the movie component you would have it based on condition (referring back to that “True” variable”. Then the stop component can forced end of routine, or code component that is based on the routine timer (then doing the same conditional statement for the stop timing).
Are you sure there is not any weird rounding of the video playback file length (might be 477.8 or something)?
In reference to onset/offset log issue, there is a fix in this thread: Onset and offset timestamps for videos - #13 by alicealbertinidrew and here Onset/offset times of the video stimuli are not saving .
For your problem 2 you state that you have your 5 seconds of text AND a camera component that is 10 seconds. However in your first paragraph you state that the camera component is in trial2 (which is 10 seconds long). Maybe that’s the issue there?
