Potential Causes that Lead to Faulty Videos

To properly diagnose and repair corrupted video files, it's important to first identify what may have caused the issue. There are several potential reasons that are common sources of video file corruption.

Hardware malfunctions: Faults in hardware such as cameras, memory cards, hard drives or other storage devices can damage videos. Issues like bad sectors on a disk or damaged connectors introduce read/write errors that can corrupt data.

Abrupt shutdowns: Removing memory cards or accidentally shutting down cameras, computers or other devices while videos are still being recorded, edited or transferred interrupts the process. This leaves files in an unfinished state that can cause playback problems and faulty videos. 

Filesystem errors: Faults in file system like corrupt allocation tables, permissions errors or bad clusters can be a reason for faulty videos. Therefore, regular backups and file system checks can help in prevention.

Virus/malware attacks: Malicious programs can damage your files and sometimes target video files. Getting infected to malware introduces unexpected changes that interfere with decoding during playback. To avoid such issues, regular scanning of your devices and storage devices are a must.

Power outages: If power is unexpectedly lost while editing or file transfers or your battery gets discharged during recording, it can improperly corrupt videos, making them unviewable. Ensure uninterrupted power supply to avoid any issues.

Compression issues: Problems with the codecs, or settings used to compress and decompress videos lead to lost, corrupted or missing frames, audio sync issues, and other strange behaviors in a video file.

File corruption can strike even under normal usage from various failure. The key is to determine where a problem originated so the issue isn't repeated and files can be repaired when possible.
