When trying to merge videos in VLC, you may encounter two common problems. You might receive errors when opening the files you want to join, or the new merged video won’t work.

One of the following solutions should help you eliminate these problems.

Fix 1: Update VLC Codecs

Codecs are programs that compress and decompress your files and enable your media players to read them correctly. If your VLC codecs are outdated, they could start causing issues and affecting your media player’s performance.

Fortunately, updating your VLC codecs takes just a couple of minutes:

Step 1: Launch VLC and click Help > Check for updates.

Fix 2: Update Your VLC

VLC codecs might not be the only outdated element. You might need to update the VLC media player to eliminate the issues of your videos not merging. The good news is that the steps for codec and VLC media player updates are the same.

Therefore, after downloading the updated files, take the following steps:

Step 1: Type %TEMP% in the search bar.

How to Ensure Your VLC Merged Videos Work in the Future

Random glitches, bugs, and other issues can affect the performance of VLC or any other media player. However, you can take several steps to minimize your chances of encountering the problem of VLC merge videos not working.

Option 1: Keep all apps and software updated.

While software updates can be annoying, they’re critical. They ensure you can access all the latest features and protect your device. They typically contain essential bug fixes and security patches to keep things running smoothly.

Option 2: Install an anti-malware program.

Malware infestation is the number one cause of corrupted files. Malicious software can destroy your images, videos, documents, and other files. It could also put your online privacy and security at risk. Therefore, ensure that every device you have has a reliable anti-malware program.

Option 3: Keep backups of your files.

Backing up your files can help ensure you always have a functional copy of any video (or other file type) you may need. You’ll always have a backup, even if a copy gets corrupted or damaged.

It’s in your best interest to back up your videos to the cloud, as they’ll always be easily accessible, and you won’t have to worry about losing the files if something happens to your device.

Option 4: Be careful with data transfers.

Your files are most vulnerable during data transfers. Even a tiny interruption could corrupt them when downloading or transferring them from one device to another.

So, always be careful with data transfers, ensuring you don’t turn off your device or interrupt downloads. Always carefully eject storage devices before disconnecting them. Moreover, keep your device fully charged during data transfers since your files could get corrupted if your device runs out of battery.
