To give you the best viewing experience, YouTube changes the quality of your video stream based on your viewing conditions. These conditions are why you may notice that the quality of your video changes as you watch videos.
Here are some factors that decide video quality:
- The speed of your internet connection
- Video player/screen size: Higher-quality videos generally play better on larger screens.
- Quality of the original uploaded video: If the video was recorded in standard definition, it won't be available in high definition.
