Description of the problem:
I have a routine in a loop that shows a movie stimulus. The file to show varies across trials. The file is updated in a 1-second ISI prior to the start of the movie. After the movie, there is another short ISI (750 ms) and then a lexical decision. This all works find in PsychoPy, but when I move it to Pavlovia, there are two problems with the movies:
(1) The movie stim sometimes doesn’t disappear after playing. The last frame of the movie stays on-screen and the lexical decision probe is displayed on top the movie. This happens about 50% of the time on Pavlovia. Is there a way to manually clear the screen after the movie finishes?
(2) This might be related to (1). The movie doesn’t always appear to be starting at the end of the 1 second ISI in which it is supposed to load. I’m assuming this is because it’s taking longer than 1 second to load the entire movie. Consequently, the movie doesn’t end until after the second ISI has started. Starting a few ms late isn’t necessarily a problem, but I do want to maintain the full 750 ms ISI between the end of the video and the presentation of the LD probe. Is there a way to ensure this?
I’ve looked through the forums, but can’t find an answer. Same with the video documentation.
