WHAT IS WRONG WITH MY VIDEO FILE?
This is the very first question on the lips of anyone who has ever had or encountered a corrupted video file. Just as we stated earlier that a video file format is a type of file format for storing digital video data on a computer system.
Videos are almost always stored using lossy compression to reduce the file size. As we all know a video file normally consists of a container containing video data in a video coding format alongside audio data in an audio coding format.
All widely spread video file formats these days have quite a complex structure. In this article, we are going to cover the following video file types: AVI, MP4, MOV, MXF, and 3GP.
In addition to video and audio data, video files contain service data, which is used by different applications such as video editing software and media players, to read the files.
The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the Essence. A program (or hardware) which can decode compressed video or audio is called a Codec while playing or encoding a video file will sometimes require the user to install a codec library corresponding to the type of video and audio coding used in the file.
The structure of video files vary depending on the file format. We will outline the following elements:
- Header: The header is where service data is stored. What kind of service data do headers contain? you ask! well, depending on the video file type and camera model, there may be a few hundreds of records about the video. To make this simple to understand, headers may contain details about the duration and size of the video stream. They also contain information about various settings used to record the video, including frame rate, bit rate, resolution, codecs, etc. These details are needed for media players, as well as video editing software to open the video file and then decode it properly when rendering it on a screen.
- Video stream: This is the actual video data that you can record with a video camera.
- Audio stream: If your camera has got a microphone and is able to record audio, then the audio stream is recorded as a separate data track in the video file.
- VOB: Files in VOB format have. VOB filename extension and are typically stored in the VIDEO_TS folder at the root of a DVD. The VOB format is based on the MPEG program stream format.
Lastly, there is an index, which is used to locate keyframes in the video stream.
When you drag a time slider in your media player, indices let the player find the right frames in the video stream and show it on your screen. Without the index, you won’t be able to use the fast forward or rewind options in your media player.
Most of the video file types can be represented as containers that include all the elements described above.
WHY IS MY VIDEO FILE NOT PLAYING?
The thing is that the issue with your video file may be caused by a damaged header, indices, or both. The issue may arise if the video file hasn’t been finalized by the camera properly. Here is how this may happen in a scenario:
Since the video files are usually quite large and they occupy a lot of space on memory cards, video cameras divide them into relatively small chunks and save those portions of data one by one. When you stop the recording, your camera saves the last portion of the video and then generates service data in the files’ header (as described above).
However, there are scenarios when your camera may lose power while on motion during the recording process. For example, the camera’s battery may run low on power. Or, you could power off your camera yourself without stopping the recording process prior to this.
If the camera loses power during the recording operation, the last chunk of the video file along with the header may be lost. As a result, the container of the recorded video file may lack (or have a damaged) header. Without the header, the video file won’t work. And this is the reason why your damaged video files can not be played.
Moreover, such corrupted video files may also have broken or even empty indices. If this is the case, you won’t be able to use a time slider in your video player.
CAN MY DAMAGED VIDEO FILES BE FIXED?
The answer is yes! For you can repair corrupted video files most of the time. However, this is only possible if the file contains actual video and audio data. If the video (and audio) streams have been saved correctly, then the missing header and indices can be reconstructed.
Checking out versions In opposite to AVI, MXF video files have the most complex structure. In particular, every single MXF file may have a unique structure of nested elements.
This makes it extremely hard to repair a corrupted MXF file. And there are almost no generic video repair tools that can fix MXF files automatically.
Fortunately, damaged MXF files can be repaired manually by qualified video engineers. There quite a few online recovery services that can handle MXF files, and Restore them.
Media is among them. If you’ve got a corrupted MXF file, you can upload it to cloud storage and then share the file with video engineers, so that they can repair it.
AVI files have the simplest structure compared to other video file types. And there are amazing data of free tools that can fix broken AVI files in just a few minutes.
These tools are very quite useful, yet simple to use. If you need to repair an AVI file, look no further, just use either of the following tools:
- VirtualDub (available for Windows users only)
- DivFix++ (available for Windows and macOS users)
- FFmpeg (available for Windows and macOS users).
These tools are completely free. There a lot of guides on the Internet on how to use them.
VirtualDub and DivFix++ have quite an easy-to-use interface, so you might not even need any additional guidelines to work around it. The FFmpeg tool doesn’t have an interface. You can use it from Command Prompt on Windows, or Terminal on macOS.
MP4, MOV AND 3GP FILES
The mp4, mov & 3gp files are the most common video file types these days, which are also prone to issues described above. But the good news is, there are quite a lot of different tools that can repair corrupted MP4, MOV and 3GP files.
