What Is an AVI File?

Audio video interleave, or AVI, is a file format for storing audio and video materials in a single unit. Although it has been around for over 30 years, it is still one of the most used and reliable video formats. The best part about these files is that they are containerized, meaning they don’t take up much space in your storage.

This format is compatible with most devices and operating systems, contributing to its popularity and use. It is a simple yet versatile file type for video and audio files.

AVI File Use Cases

AVI files can serve many different purposes. Their versatile format provides the convenience you need to store your video and audio files. Let’s look at some of the most common use cases of AVI files:

  • Older videos – If you have video files from the ‘90s, they are probably in the AVI format. You can also use this format to preserve such older memories.
  • Medical readings – Many healthcare institutions use AVI files to store medical records due to their size and ease of use.
  • Legal evidence – Lawyers and forensic experts use AVI files to preserve and present crucial evidence in court.
  • Educational videos – Teachers and professors often create AVI files containing all the necessary data and facts to help students better understand topics.

These are just some of the most popular use cases. However, you can use AVI files whenever you find it convenient.

Symptoms of Corrupted AVI Files

Look out for the following symptoms to detect corrupted AVI files:

  • Lags – If you experience lags when playing an AVI file, it might be a sign that the video is corrupted.
  • Inability to play the video – This sign is the most obvious indication that something is wrong with your AVI file.
  • Inability to use control buttons – Your file might be corrupted if you can’t skip, reverse, or pause the video.
  • Freezing – A video might freeze on a particular frame if the file has corrupted elements.
  • Audio issues – The video and the audio may not be in sync, or you may not hear crystal-clear audio. If so, check for corruption issues.
  • Image distortion – Some frames in your AVI files may seem crooked and distorted, which is a common sign of file corruption.
  • Error messages – Another sign of file corruption is an error message greeting you when you try to play a video.
