Videos have become an important part of our digital lives. You enjoy watching them on your PC. But sometimes they may stutter and lag causing immense irritation and frustration. You want the error fixed immediately so that you can continue to have an enjoyable video-watching experience.

Before you call in a technician to sort out the problem, it is important to know that this is a common error which you can fix yourself. But first, you need to understand why the issue occurs in the first place.

Why do videos lag or stutter? There is a wide range of reasons including the following:

  • Outdated, missing, incompatible, or corrupted graphics drivers.

  • Outdated, missing, incompatible, or corrupted audio drivers.

  • Windows Operating System updates are not installed.

  • Slideshow wallpaper settings.

  • A wrong power plan setting.

  • Malware infection.

  • Outdated media player.

  • Slow PC with insufficient RAM.

  • Hardware faults.

  • Corrupted video files.

Part 1. Symptoms and Causes of Video Lagging or stuttering

Symptom 1: Flickering or patchy videos.

Cause: Windows 10/11 slideshow wallpaper setting. If it has a short time interval, videos can skip a frame every time a new background comes on, hence the flicker. Outdated video drivers are also known to cause the error.

Symptom 2: Video glitches and stuttering

Cause: Background applications. These applications clog system resources such as RAM. Insufficient RAM can cause videos to stutter and lag. The error can also occur when audio and video drivers are outdated and Windows updates are not installed.

Symptom 3: Blurry, jerky videos.

Causes: Corrupt SD cards, incompatible or outdated media players, insufficient disk space, missing components, and defective encoding are the known culprits.

Symptom 4: Video and Audio Out of sync

Cause: Out of date or corrupt device drivers.

Symptom 5: Inaccessible Video File

Cause: Corrupted video file, a malware infection.

Symptom 6: Blank/Black Screen. When you click play, all you see is a back-screen video timer moving forward or stuck in one position.
