Hey Dave, dear Communiry,

I have a question regarding video playback.

I want to have an experiment running where a video gets played in the background. While the video is running, I want the participants to press on appearing circles. However, the video should continue to run after a click, the circle should disappear, and a different circle should be displayed a few seconds later.
Sadly, I don't have a clue, how to do it. I think to log a response, Inquisit has to end the trial, right? One option I thought about was to keep track of the runtime, then start a new trial after the circle was pressed but restart the movie at that runtime. But I don't see an option on how to do that.

I would be very grateful for a response.

Best,
Daniel

In that case, you'll want to display the video via the block's /bgstim. It'll keep running throughout the block, while the block runs its trials. You'll want a trial to display a circle (which should also be implemented as a video (e.g. an animated gif, else the background video will erase the circle after one frame by overwriting it),  until the participant clicks on it. Then run the next trial, and so on.
