How to Fix Buggy Videos?

It’s frustrating when you need to play a video and it turns out to be buggy or damaged. This can ruin your video-watching experience and worse if you don't know the cause of this issue.

From sudden power cuts to incomplete video transfer, buggy videos can result from different reasons. Some of the common causes of corrupt MP4 videos are:

  • Incomplete video transfer or download
  • Sudden computer shutdown or a power cut and OS crash
  • Virus or malware infection
  • Outdated media players
  • Using the same SD cards in multiple devices
  • Problem with the audio/video codec
  • Outdated drivers
  • Corrupted or damaged video files

No matter why your videos stored on your Mac or Windows PC get damaged or become buggy, you can repair them using a manual or video repair software approach.

Here in this article, we explained different workarounds and methods to repair buggy video files.

Workarounds to fix buggy videos

Below are the three workarounds you can try to repair buggy videos on a Mac or Windows PC:

1. Play the video in another media player

If buggy videos are not compatible with your existing media player, change the media player. Try playing your videos in VLC Media Player, Windows Media Player, Winamp, QuickTime Player, Cisdem Video Player, KM Player, etc.

2. Change the file format

Changing your video's file format can often help fix damaged or buggy videos. You can convert the video format to VLC Media Player or any other online video converter like CloudConvert, FreeConvert, etc.

3. Update Graphics Drivers

Outdated graphics card drivers often lead to choppy or buggy videos. Visit the official website of your GPU manufacturer, such as AMD, NVIDIA, or others, to download the latest version of graphic card drivers.

Methods to fix buggy videos

Use online video repair tools or any professional video repair tool to fix buggy videos.
