How large are the movies? Both in file-size and resolution.

resolution: 1920x1080 30 frames per second file size: varying from 300 mb to 1 gb

Hi mariette. So I’ve been experiencing the exact same thing. I’m just using 400kb movies and it takes a while for them to load each trial. I’ve tried a million things, including changing movie formats, codecs, resolutions, etc. I’ve noticed that if i use “constant” instead of “set every repeat” in …

[image] Falexs: I’ve noticed that if i use “constant” instead of “set every repeat” in the movie component, the movies actually run fine. That’s really useful information. If you set the movie to constant and then update it in code at a point where you don’t mind a short delay (e.g. just afte…

I’m having a hard time updating a movie component that is set to “constant”. Even if I ask him in the next routine (following the previous trial) to update the filename of the movie, the next trial will display the same movie. Can you elaborate further?

Thanks! It works, but now it moves my loading time to just before the routine where I have the code setting the new video. So, i see the first video (first trial) ok, but transitioning to the following routine (in this case the response screen) where i have a code chunk specifying the new movie name…

Hello, loading times of videos seem to be a problem currently. If you set the movie to constant, it will be preloaded at the beginning of the experiment. Thus no delay in the movie-routine. You could insert an ISI-component at the beginning of the relevant routine. This ISI-component should last …

thanks for the quick replies! The movieComponentName.setMovie(fileNameVariableWithPath) does not work here. I get the message NameError: name ‘xxxx’ is not defined. What do I do wrong?

Hello Jens, Thanks for the idea. It helps somewhat. Although it still forces me to have an ISI of >3s to account for movie loading. Ideally, to make the experiment shorter I wanted 1s inter-trial intervals at most. However, i recognize that this might just be impossible at the moment even with 400k…
