Description of the problem: freezes in videos and continue playing the sound of video while the video stoped by the keypress!
Hi. My experiment includes 144 videos and 144 characteristic sounds. In each trial, of the experiment, a word will be shown for 2s and after a 200ms interval page, a characteristic sound plays for 600ms. After 100ms from the characteristic sound onset, the video clip will be started and continues for 2s while a key response is available to the participant from video onset. It means that there is a 500ms overlap between characteristic sound and the video (as shown in my builder view). I got two problems:
- There are freezes during video play. The format of videos is mp4 with an h.264 codec.
- When the key responses are pressed, the sound of videos still remains to play to the end while everything has stopped and the next trial comes out!
I would be pleased if anyone could help!
