One day, I tried to watch a video of my memories, but it wouldn't play...
I'm sure there are many people out there who have had similar experiences.
I also work in video production, so I have a lot of experience like that.
In my case, it would be fine if it was just me, but since the other party is a client, it sends shivers down my spine when the video suddenly crashes.
So Data is like the devil incarnate, carrying that bomb.
Especially on a Mac, there are few apps you can rely on when you can't play the video.
This time, I would like to introduce an app that will help you say goodbye to such worries.
What are the main reasons why videos won't play on Mac?
There are various other reasons why a video may not play or may stop, but we will list the most common ones below.
1. Unsupported file format or codec issue
- CauseIf the video you are trying to play stops, it may be because the video is in a format or codec that is not supported by the standard Mac player (QuickTime Player).
2. Corrupted video files
- Cause: The video file may be corrupted due to an interruption during download, an error during file transfer, or a problem with the storage device.
3. Outdated or Unsupported Software
- Cause: If your macOS or video player version is old and does not support the latest codecs or formats, you may not be able to play the video.
4. File permissions and security settings
- Cause: The file permissions may not be set correctly or the video may be blocked (stopped) by security settings.
5. DRM Protection (Digital Rights Management)
- Cause: The video is DRM protected and you don't have a license to play it on your Mac.
I think these are the main causes, but the most unpleasant case is still "2".
In other cases it may be possible to manage, but when files become corrupted it's a depressing situation.
But file corruption can happen suddenly, so you need to know how to deal with it.
What can you do to fix a video that won't play?
Recovering videos from a macOS backup
If you cannot play the video, first try to restore it using the macOS backup function. If you are using Time Machine, you can easily restore the video to the state before it was corrupted.
All you have to do is open Time Machine, select the backup from the date and time the video was saved, and restore it. This may undo the changes that caused the corruption and return the video to a playable state. If you make regular backups, this is the easiest and most reliable method.
Use a dedicated video repair software
If you don't have a backup or restoring it doesn't fix the problem, you can always turn to professional video repair software. Tools like 4DDiG File Repair or Stellar Repair for Video use highly advanced algorithms to repair corrupted videos.
These software programs have the ability to fix video formats and codecs, improve frame and audio synchronization, and attempt to repair any level of corruption, especially corruption caused by interruptions during recording or transmission errors.
