How Video File Get Corrupted?

Now the question arises, why are you experiencing corruption in video files? The reason for corruption can be because of any unperceived problems that you might encounter during video shooting, the virus on your memory card, data communication issue while you try to transfer files to your PC, or others.

What happens when videos are corrupt?

To know the answer to this question, you need to understand the structure of a video file. You see, a video file is a sequence of bytes that has two parts: header and data part. The header part is the set of bytes allotted to store the metadata about the video such as file type, a start bit and end bit, offset, etc. While the data part stores the actual bits that represent the video.

When few bits of a header is changed then this file may not play in a video player. Besides, change in bits from the data part makes the video jittery, grainy, out of sync with audio, or distorted when played. In either case, the video file becomes corrupt.
