Why Do Videos Get Corrupted?
Now that you know multiple ways to repair video files, you can pick one that suits you best. However, before delving into the repairing process, you must figure out the reason for file corruption. It is essential to understand the causes because it’s the only way to apply the correct and appropriate methods. Thus, review some common causes of file corruption briefly explained next:
- Sudden Power Loss: If your computer loses power during video recording or sharing, the process might be affected. It can leave the file incomplete, and users may experience issues like missing frame rates or audio.
- Software Crashes: Your software may crash during video recording or editing due to system overload or bugs. If the file is left in a partially saved state, it will become corrupt and unreadable.
- Malware Infection: Sometimes, malicious software can infect your system and corrupt video files. It can make your files inaccessible or lead to content alteration or destruction, part of a ransomware attack.
- Codec Issues: Notably, a codec is a software component that decodes and encodes video files. If it is not installed correctly and disrupts playback, your attempts to force playback can lead to file corruption.
- Improper Removal of Media: Removing a USB card or other storage device without ejecting it can cause corruption. Your operating system may still be writing data to the device, and improper removal can interrupt the process.
- Interrupted File Transfer: When the file transfer process suddenly stops due to device failure or accidental disconnection, corruption occurs. It can make your video files unreadable; sometimes, re-transferring can resolve the issue.
