I am creating an experiment in which I want to present 63 videos at 1 second each. The videos are (currently) all .avi files and their large is (around 459 KB ). Therefore, I have added them all to the experiment folder (instead of loading them directly into the file pool) and am using legacy as a backend. I want to define four blocks with two repetitions in each block. Each block consists of 63 one-minute videos. However, every time I run the experiment I can not complete it, because it has a memory problem. Additionally I use media_player_mpy and some videos get stuck when i run the experiment. For example, only the sound can be heard and the image remains stuck.Do you know what I can do about it?
