Dear jp-psycholojs, thank you very much for you response! I have deleted the loops in first three trial sessions and wrote the path exactly to the file. The last loop - actual experiment, seems to work quite ok, although one more problem occurred - while presenting the video, only audio works, video isn’t displayed (only the background colour is visible). I have checked similar topic ([Problem with running video files in Pavlovia - #4 by jonathan.kominsky](https://discourse.psychopy.org/t/problem-with-running-video-files-in-pavlovia/12770/4)) where the solution was to encode .mp4 with h264 codec, so I tried this, but unfortunately it still doesn’t work. Those are details of one of my video files: ![Screenshot 2020-10-04 at 16.46.36](https://us1.discourse-cdn.com/flex002/uploads/psychopy/original/3X/b/3/b3db2c4771ffcd6214481f7b81afc283414e076f.png) I have deleted the experiment and uploaded it again, here is the new link: [Karolina Ćwik / test7 · GitLab](https://gitlab.pavlovia.org/karolina.cwik/test7) Thank you very much in advance 🙂 Karolina --- _[View the full topic](https://discourse.psychopy.org/t/pavlovia-takes-only-first-letter-of-csv-xlsx-condition-files-cell-unknown-resource-issue/16960)._
