Part 1: Overview of MOV Files Format

MOV video is a well-known file format developed by Apple Inc. It contains several tracks to store different media files, especially videos, in a multimedia container. MOV videos are specifically designed to play on Quick Time Player and use MPEG-4 codec for file compression. Their distinct design gives them an edge over other file formats regarding the ease of editing. But only a few players support this file format. However, MOV videos are compatible to play on both Windows and Mac devices. 

Part 2: What Causes MOV File Corruption?

Like any other video file, MOV files can also become corrupted, and there are several reasons behind their corruption and damage. They include:

Abrupt Shutdown: If there is an improper or abrupt shutdown of your system, it can cause damage to the structure of MOV files.

Ineffectual Format Conversion: While converting MOV files to another format, several problems can develop if the application used for conversion is ineffectual. Or if there is an interruption during the conversion process, it can also cause MOV file corruption.

Incompatible Video Player: Video players incompatible with the MOV file format can overwrite headers, making the media inaccessible or corrupt if you use them to play MOV files.

File Transfer Interruptions: While transferring MOV files to another medium, a power outage or other interruptions can corrupt them.

Issues in File Compression: If you are using an incorrect application to reduce MOV file size, this could cause MOV file corruption. Or if you didn’t follow the compression process to a logical result, this may also cause damage to MOV files.

Bad Sectors On a Drive: Storing MOV files on a drive with bad sectors or a physically damaged storage medium will affect their viability, causing corruption.

Virus Or Malware Attack: Virus or malware attacks targeting the system or, specifically, the MOV videos can damage the files' internal structure, resulting in corruption.
