With YouTube videos, it is possible to modify the start and end times of the video. The easiest way to do so is to stop the video where you want the video to start, and then click the “Share” button in YouTube, which allows you to select the start time and then copy the URL. Alternatively, you can add the “t=..." parameter to the end of the URL of the video. An example would be this: https://youtu.be/orLEUSNYpCo?t=33 When you add this URL to your video player, the video starts at 33 seconds.
