Why Does My YouTube Video Change Quality?

Have you ever noticed that the quality of your YouTube video changes while playing? Maybe it starts off in high definition, but then suddenly drops to a lower resolution.

This can be frustrating, especially if you’re trying to enjoy a video with clear visuals. In this article, we’ll explore why your YouTube video changes quality and what you can do about it.

Why does it happen?
YouTube adjusts the quality of your video based on several factors such as the strength of your internet connection, the device you’re using to watch the video, and the size of your screen. When you start playing a video, YouTube will automatically choose the best possible quality for that particular moment. However, if any of these factors change during playback, YouTube may adjust the quality accordingly.

How does YouTube adjust quality?
YouTube uses a technology called Dynamic Adaptive Streaming over HTTP (DASH) to adjust the quality of videos in real-time. DASH divides each video into small segments and stores them on servers around the world. When you start playing a video, YouTube will request these segments from servers closest to your location.

As each segment is played, YouTube measures your internet connection’s speed and adjusts the quality of subsequent segments based on that speed. For example, if your connection is slow at a particular moment or if there’s network congestion, YouTube may decrease the resolution to ensure smooth playback and avoid buffering.

What can I do about it?
You can manually adjust YouTube’s video quality settings by clicking on the gear icon in the bottom right corner of any video player. From there, select “Quality” and choose one of several available options ranging from 144p to 1080p or higher if available.

If you want to avoid automatic adjustments altogether, select “Advanced” instead of “Auto” under Quality settings. This will allow you to manually select a specific resolution for playback and prevent any automatic adjustments while watching.

Conclusion
Dynamic Adaptive Streaming over HTTP technology is what enables YouTube to adjust the quality of your videos in real-time. While it may be frustrating to experience sudden changes in video quality, it’s essential for ensuring smooth playback and a seamless viewing experience.

However, you can manually adjust the quality settings in YouTube to control the resolution of your videos. With this knowledge, you can now enjoy your favorite content on YouTube without worrying about any unexpected changes in quality.
