Videos are indispensable part of our lives — from home, office, school to college projects, they are used everywhere. But the more videos you create, the more video-related issues may surface.

Here, we will guide you how to fix the video problems that occur due to file corruption.

Signs and causes of video corruption

If your videos are giving playback errors, or stuttering, flickering, playing choppy, jerky, or out-of-sync, it indicates file corruption. The videos may become unreadable, and some might not open at all due to corruption.
Although it’s annoying to lose favorite movies and videos to corruption, technical glitches are often unavoidable. Irrespective of the video quality and camera type, videos can get corrupt anytime — while recording, processing, or when you’re trying to save them in your USB or hard drive.

There could be many reasons for video file corruption:

  • Sudden power cut, system shutdown, or OS crash
  • Virus or malware attacks
  • Bad sectors in the storage drive
  • Physically damaged hard drive or media

These unavoidable technical malfunctions can damage the video file header, data, sound sections, and frames. So technically, you can say, your videos appear distorted or won’t open because of the following:

  1. Header corruption
  2. Data corruption
  3. Frame corruption
  4. Track corruption

Let’s understand them better and know what video issues you may face in each case and how to fix them.

Case 1: Video File Header Corruption

A file header is at the beginning of a file and contains metadata information about the file. It holds specific video file attributes such as file format, audio codec, size, resolution, camera model, video settings, and so on. Any software would first read the header information to open a video file. But if this header gets damaged or broken, no media player would be able to read the video file.
Videos with broken file header may show errors, such as

‘Windows media player encountered an error while playing this video.’
 ‘Can’t play video. Error occurred.’
‘Loading media file could not be played.’

Sudden interruption such as power outages, OS crash, or other reasons while downloading a video, can corrupt the file header. Software like Stellar Repair for Video can rebuild damaged file header, making the video accessible again.

Case 2: Video Data Corruption

A video file that has corrupt data behaves abnormally. It may give an error message, show black screen, bright, flashy color bands, or no sound, etc.

Data corruption in a video occurs when some unintended changes are made to the file’s original data. Sudden interruption during the read/ write process, transfer of file, or processing in a video editing app can corrupt the file data. Damaged storage drives and media that developed bad sectors, can also damage video file information.

A professional video repair tool can only fix corrupt data in media files making the video perfectly playable. Make sure the software supports the file format of the corrupt video.

Case 3: Video Frame Corruption

Choppy, broken, jerky, stuttering, splitting, or audio lag in videos point towards frame corruption in the file.

Corrupt or missing frames in videos can be caused due to a virus, malware, sudden power failure, OS crash, system shutdown, etc., while transferring, viewing, or editing a video file. You can repair video frame corruption using advanced Stellar Repair for Video software.

TIP: You cannot repair a missing frame using any video repair tool. Try morphing in such case, for a seamless transition from one frame to another in a video.

Case 4: Video Track Corruption

A video file consists of a container that has both audio and video data. If you’re facing missing sound, audio lag, or video sync issue, it indicates corruption in the sound section.
The advanced algorithms of software like Stellar Repair for Video can automatically reconstruct damaged audio data structure and video data.

Repair corrupt videos using professional video repair software. Video repair tools automatically fix broken or damaged file information making the videos playable again. An advanced tool would resolve stuttering, choppy, flickering, black screen, no sound, out-of-sync, and other video issues caused by file corruption. But not every repair tool is programmed to fix all kinds of video corruption. Some may repair a corrupt file header or data but may not be equipped to fix sound sections. Other tools like FFmpeg repair corrupt videos but use complex command lines. They require technical knowledge, which a novice user may not have.
