Part 1. Symptoms and Causes of Video Lagging or stuttering

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

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 Outdated video drivers are also known to cause the error.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 The error can also occur when audio and video drivers are outdated and Windows updates are not installed.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Causes: Corrupt SD cards, incompatible or outdated media players, insufficient disk space, missing components, and defective encoding are the known culprits.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Cause: Out of date or corrupt device drivers.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.

Cause: The video file is corrupted or not all the parts were copied properly from source media, missing codec, outdated video driver, and malware infection.

Symptom 7: Video freezing

Cause: Corrupted video file due to malware infection or interruption during downloading.

Symptom 8: No audio or video

Cause: Missing, corrupted, or outdated audio and video drivers, outdated Windows.

Symptom 9: Video File Not Playing

Cause: The Windows Media Player does not support the video format, missing or unsupported video codec. Video codec is the software that is used to compress and decompress videos.

Symptom 10: Video playing slowly or sluggishly.

Cause: Slow computer with insufficient RAM, corrupted video file, browser settings, outdated media player, outdated video drivers, and corrupt video file.

Symptom 11: Video distortion (pixelated, stretched, or broken videos)

Cause: Missing, outdated, or corrupted graphics drivers, outdated media player, faulty CPU, hardware failure.
