### How the Video Plays in Class

Once you have [published your changes](https://help.wellioeducation.com/how-to-edit-a-lesson?hsLang=en#publish), all YouTube videos are displayed using Vlite, a secure player. This ensures that:

- Playback is **locked** to the define video segment
- There are **no ads**
- You **can’t skip ahead** or accidentally drag the time bar
- If you refresh or exit the video, it will **restart from the defined start time**
