近年来，几乎所有的视频媒体都从磁带上的模拟存储转移到计算机硬盘上的数字存储( digital storage on computer hard drives)。这是一件好事，因为数字媒体可以轻松备份，并且不会随着时间的推移而退化。
不幸的是，当文件损坏且无法打开时，数字视频存储的所有好处都会丢失。(video storage)但是，有一些方法可以修复和播放损坏或损坏的视频文件，本文应该可以帮助您恢复数据。
修复损坏的视频的奇怪怪癖之一是，并非所有修复视频文件的技术都可以(video file work)始终有效。如果本文中的一种方法第一次不起作用(t work)，请不要灰心！(Don)
检查您的驱动器
在尝试修复视频文件(video file)之前，有必要确认该文件是问题所在，而不是您的硬件。如果您使用需要单独电源(power supply)的外部硬盘驱动器，请尝试更换电源(power supply)并查看是否可以解决问题。检查您的驱动器是否有错误也是值得的。
如果您使用的是USB 驱动器(USB drive)，请尝试通过有源USB 集线器(USB hub)连接它。欠压会导致各种难以调试的错误，因此值得排除。USB 驱动器容易损坏(USB drives are prone to damage)，并且可能是您的问题的根本原因(root cause)。
最后，尝试在VLC(VLC)媒体播放器等其他程序中打开您的视频文件。有时系统(Sometimes system)更新可能会导致默认视频软件(default video software)在打开某些文件类型时出现问题。像VLC(VLC)这样的免费视频播放器通常更擅长播放更多种类的文件。
恢复损坏或损坏的视频文件的最简单方法是让其他人来做。Fix.Video 之类的(Fix.Video)在线(Online)服务会收取上传的损坏视频文件，并收取少量费用对其进行修复。
存在免费的视频恢复(video recovery)服务，但您的分辨率和最大文件大小(resolution and max file size)选项将受到限制。他们通常也会在您的视频文件中添加水印。
如果您正在寻找损坏视频文件(video file)的免费解决方案，请尝试以下一种软件方法是一个更好的主意。
使用 VLC 媒体播放器恢复损坏的视频(Recover Corrupted Video With VLC Media Player)
VLC 媒体播放器(VLC media player)是目前最好的免费视频播放器之一。它也是转换和修复视频文件的强大工具。VLC 的文件转换过程(file conversion process)具有修复损坏视频的有用副作用。请按照以下步骤尝试恢复您的文件：
- 打开媒体(Media)菜单。
- 选择Convert/Save.
- 使用“添加(Add)”对话框选择您的文件。
- 单击Convert/Save.
- 从下拉菜单中选择Video -H.264 + MP3 (MP4)
- 单击浏览(Browse)以输入转换文件的文件名。
- 单击开始。(Start.)
转换可能需要一些时间，但如果成功，您现在应该可以查看损坏的视频。如果它不起作用(t work)，您可以使用VLC采取另一个步骤：
- 制作视频文件的(video file)备份副本(backup copy)。
- 将文件的扩展名更改为.avi。
- 打开 VLC 并前往Tools > Preferences.
- 在Input / Codecs下，查找Files部分。
- 在损坏或不完整的 AVI 文件(Damaged or incomplete AVI file)下拉菜单下，选择始终修复。(Always Fix.)
- 打开扩展名为.avi的视频文件。
此设置指示VLC媒体播放器尝试恢复它遇到的任何损坏的AVI文件。(AVI)需要耐心(Patience)，因为这可能需要一些时间。
使用视频修复工具恢复损坏的视频(Recover Damaged Video With Video Repair Tool)
要获得更强大的视频恢复工具(video recovery tool)，您需要寻找专业软件，例如Grau GmbH 的 Video Repair Tool(Video Repair Tool from Grau GmbH)。很少有其他软件采用如此彻底的数据恢复手段。然而，问题在于价格。五次转换许可证(conversion license)29欧元，无限制使用许可证(use license)99 欧元，对于大多数用户来说可能太贵了。
有一个免费版本，最多可以恢复一半文件，正如YouTuber R3DLIN3S所示，它很容易被利用：
也就是说，如果这个软件在其他人没有的地方工作，你应该购买许可证来支持开发人员说谢谢！
如果您在Linux 系统(Linux system)上工作，那么您的软件选择似乎很有限。虽然您可以通过使用 Wine 运行 Windows 应用程序来(Windows applications using Wine)解决这个问题，但也有一些本机选项。
对于修复损坏的AVI 视频(AVI video)文件，DivFix++是一个历史悠久的免费选项。下载并安装后，您可以使用DivFix++使用以下步骤修复您的数据：
- 单击添加文件(Add Files)并选择您的视频文件。
- 选择检查错误(Check Errors)以执行文件扫描。
- 选择保留原始文件(Keep Original File )复选框以备份您的源视频(source video)。
- 单击修复(Fix)按钮。
请注意，即使错误扫描显示数据没有问题，也值得尝试修复，因为有时修复过程(repair process)可以解决文件的未知问题。
旧文件的新生活
无论您将视频存储在本地硬盘驱动器(local hard drive)还是云中，文件损坏始终是一种威胁。除了上面建议的恢复方法外，最好设置一个备份系统（(set up a backup system)在 macOS 上(Time Machine on macOS)也称为Time Machine ），以防止丢失数据。
How To Repair And Play Corrupt Or Damaged Video Files
In recent years, almost all video mеdia has moved from analog storage on tаpes to digital storage on computer hard drives. This is a good thing, as digital media can be easily backed up, and doesn’t degrade over time.
Unfortunately, all of the benefits of digital video storage are lost when a file becomes corrupted and won’t open. There are ways to repair and play damaged or corrupt video files, however, and this article should help you recover your data.
One of the odd quirks of fixing corrupted video is that not all techniques to repair a video file work all of the time. Don’t be disheartened if one of the methods in this article doesn’t work the first time!
Check Your Drive
Before trying to repair a video file, it’s worth confirming that the file is the problem and not your hardware. If you are using an external hard drive that requires a separate power supply, try changing the power supply and seeing if that fixes it. It’s worth checking your drive for errors too.
If you are using a USB drive, try connecting it through a powered USB hub. Undervoltage can cause a variety of hard to debug errors, so it is worth ruling out. USB drives are prone to damage and could be the root cause of your problems.
Finally, try opening your video files in a different program like VLC media player. Sometimes system updates can cause default video software to have problems opening certain file types. Free video players like VLC are usually better at playing a wider variety of files.
The simplest way to recover broken or corrupt video files is to get someone else to do it. Online services like Fix.Video take uploaded corrupt video files and fix them for a small fee.
Free video recovery services exist, but your options for resolution and max file size will be limited. They usually add a watermark to your video files too.
If you are looking for a free solution to a broken video file, trying one of the software methods below is a better idea.
VLC media player is among the best free video players out there. It’s also a powerful tool for converting and repairing video files. VLC’s file conversion process has the useful side-effect of fixing corrupted video. Follow these steps to try and recover your files:
- Open the Media menu.
- Select Convert/Save.
- Use the Add dialog box to choose your file.
- Click Convert/Save.
- Choose Video -H.264 + MP3 (MP4) from the drop-down menu.
- Click Browse to enter a filename for your converted file.
- Click Start.
Conversion can take some time, but if successful, your corrupted video should now be viewable. If it didn’t work, there is another step you can take using VLC:
- Make a backup copy of your video file.
- Change the file’s extension to .avi.
- Open VLC and head to Tools > Preferences.
- Under Input / Codecs, look for the Files section.
- Under the Damaged or incomplete AVI file dropdown, choose Always Fix.
- Open your video file with the .avi extension.
This setting instructs the VLC media player to attempt to recover any corrupted AVI files it encounters. Patience is required, as this can take some time.
For a more robust video recovery tool, you’ll need to look for professional software like Video Repair Tool from Grau GmbH. Few other pieces of software employ such thorough means for data recovery. The catch, however, is the price. At €29 for a five conversion license, and €99 for an unlimited use license, it’s likely going to be too expensive for most users.
There is a free version, which will recover up to half of a file, and as YouTuber R3DLIN3S shows, it’s quite easy to exploit:
That said, if this software works where others did not, you should buy a license to support the developers to say thank you!
If you are working on a Linux system, your options for software can seem limited. While you can get around this by running Windows applications using Wine, there are some native options too.
For fixing corrupt AVI video files, DivFix++ is a free option with a long history. Once downloaded and installed, you can use DivFix++ to repair your data using the following steps:
- Click Add Files and select your video file.
- Select Check Errors to perform a scan of the file.
- Select the Keep Original File checkbox to backup your source video.
- Click on the Fix button.
Note that even if the error scan shows no problems with the data, it’s worth trying the fix as sometimes the repair process can solve unknown issues with the file.
New Life For Old Files
Whether you store your video on a local hard drive or in the cloud, file corruption is always a threat. Alongside the methods for recovery suggested above, it’s good to set up a backup system (also known as Time Machine on macOS), to prevent losing data.
