The. MOV file format was developed by Apple for playing videos on the QuickTime player. Introduced in 1998, MOV is essentially an MPEG4 video container file format supported on Windows and macOS systems to fix corrupt mov files. Common programs that play MOV files include Apple QuickTime player, VLC Player, Windows Media Player, Roxio Creator, etc.
Often users complain that they cannot play a MOV video file due to corruption— the video file playing smoothly until now suddenly stops playing or faces issues like grainy patches, deprecated quality, or remaining stuck at a specific point. These issues are broadly categorized as MOV file corruption, resulting from an incompletely downloaded file, faulty video compression or editing, broken header, etc.
This blog shares the methods to repair corrupt MOV files, thereby recovering & restoring them to a playable form. But, before we jump over to the repair methods, let’s go through the common reasons behind MOV file corruption, as follows:
Reasons for MOV File Corruption
Following are some of the common reasons:
- Video compression issues
Compressing a video involves reducing the number of bits required to render a video sequence. So, a fault in MOV file compression may affect video rendering, resulting in corruption. Similarly, editing or conversion issues can affect MOV file rendering, leading to a type of corruption.
- Incomplete download
If you are attempting to play a downloaded MOV file, the chances are that it is not playing because it is incomplete. This case happens when Internet connectivity is disrupted while a file download is in progress, resulting in a partially downloaded file that you cannot play.
- Broken video header
A video header is a file area or section comprising vital information that allows a program to read and play the video. If the header is inconsistent or has missing information (i.e., the header is broken), you will face issues with playing the MOV or any other video file.
- Power disruption
If a MOV file is abruptly stopped or closed due to a sudden system shutdown caused by reasons like power disruption, chances are the video file will turn out corrupt or face a playability issue. This case may happen due to inconsistencies in the file header information.
