Why Do Video Files Become Corrupt?

Some of the most common scenarios under which your video might get corrupted are as follows:

Improper Conversions: Converting video files for compatibility can be risky with unreliable tools. Careless video editing can also lead to corruption, rendering MP4 videos unplayable.

File System Errors: The file system on a storage device manages files on your SD card or other storage. Leading to playback issues like audio-video sync problems or MP4 files missing video or audio.

Outdated Drivers: Drivers enable communication between a PC’s hardware and Windows. Outdated drivers can create compatibility issues, leading to video errors.

Virus Infection: Viruses or malware can corrupt files on a device. If infected, recorded videos from cameras may become corrupted and unplayable.
