The only difference is that here I use movies whereas in the others I use images. I found a post saying it could be because of .avi extension incompatibilities, so I converted to the recommended .mp4, but it still hasn’t worked. I also tried using different sizes for the movies, but I don’t think this is the problem. It works fine offline and I have no code component, so I think it cannot be a problem with “import”.
Also, in the console I have this error:
I have read similar posts but couldn’t solve it, and any help would be much appreciated.
I’m seeing an error in the line containing name: ‘movie_left’ in :
//------Prepare to start Routine 'trial'-------
t = 0;
trialClock.reset(); // clock
frameN = -1;
// update component parameters for each repeat
movie_leftClock = new util.Clock();
movie_left = new visual.MovieStim({
win: psychoJS.window,
name: 'movie_left', units='norm',
movie: obj1,
pos: [(- 0.5), 0],
size: [0.5, 0.5],
ori: 0,
opacity: 1,
loop: true,
noAudio: false,
});
Are you defining the movie in a code component or a Builder movie component? If a code component then I think that the issue is that you are creating the movie in Begin Routine rather than Begin Experiment. I haven’t tested movies myself yet, but I found that ShapeStims had to be defined in Begin Experiment so I suspect this is true of movies too.
Perhaps the issue is that you are attempting to create multiple movie components, all with the same name.
Use Developer Tools (Ctl-Shift-I in Windows/Chrome, Cmd-Opt-J in Mac/Chrome, F12 in IE/Edge, Ctrl-Shift-J in Windows/Safari, Ctrl-Opt-J in Mac/Safari) to view errors via the browser console if you aren’t getting sufficient information from PsychoPy. You can add console.log(var); to your Javascript to check the value of a variable var at a particular point.
Hi, thank you for you help, and I am sorry to bother you again.
You were right about the error being in this line, it is also happening in the silliest experiment I designed using my movies and movie components in Builder:
The .js file is being created, but there is still an error in this line. I changed to different unit types, so it does not seem to be the problem.
"Hi @tim, this is a syntax error in the JS code compiler. It relates to the units param used for your movie stim. This was a bug that has been fixed for the next release of PsychoPy, but in the mean time, I suggest you either set the units to “from exp settings” and resize your video accordingly, or manually edit the JS code to fix the syntax error (specifically line 305 where the units are set for the movie stim). To do this, you will need to do the following:
Go to Experiment Settings > Online and set “Export HTML” to “manually”
Open your JS file (found in the HTML folder) and change line 305 so units in the movie stim are set using a colon, not an equals sign e.g., should be units : 'cm' .
Save file and resync with Pavlovia
If you choose to manually edit the file, then two things to remember. 1) if you make changes to the experiment, you will have to manually recompile the experiment so the new changes are written to the JS (done using the File > Export HTML from Builder), 2) your manual changes will be overwritten if you recompile your task."
