Hi Florian thanks for the fast reply
I just try again with the same video and I even use the higher video resolution. All work fine even I can record my time!, that never happen since my first trial. All my video in mp4. However, there is two problem:
1) instead using blank screen I use fix cross that run too long (setting exp.clock.wait in 2000 ms) in inter trial interval but it seems the cross never change until I press the key.
2) Still there is notification in CMD Windows :"1 video frame (s) dropped!"
Thanks for your answer and for creating Expyriment!
As i mentioned before, the higher the resolution of the video, the more likely it is that frames are dropped. There is no hardware acceleration in Expyriment for decoding videos, which means it is all done in software. If your computer is not powerful enough to decode high resolution video on the fly, then you either have to run the experiment on a better speced computer, or if this is not an option, recode your video in a lower resolution.
Yes, we can help, but in order to do so we need a lot more information from you. In most cases, it is easier to design your experiment without the video and only once you have it working correctly, add the video parts. But that depends of course to some extent on the paradigm that you have in mind. So, I suggest following approach:
Clearly describe the essential elements of your design, incl. your attempts of implementation
While your waiting for our response, already get familiar with Opensesame, e.g. by doing the tutorials.
Together with some guidance of use, you'll be able to fix your experiment yourself.

Hello, could someone help me create a video experiment?
I don't know anything about programming and I need to run videos for a university experiment. Thanks

Hi Patri,

Does that make sense?
