How to open MTS3 file?

The main problem with MPEG Transport Stream Format is that the MTS3 file is incorrectly associated with programs. This causes the file MTS3 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MTS3 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install VLC media player

In this case, you should first verify that the VLC media player application is installed on the computer. The easiest method is to use the system search engine by entering the program name VLC media player in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support MTS3 files.

Programs to open MTS3 file

Remember to download programs supporting MTS3 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of VLC media player with MTS3 files

However, it may happen that the application itself does not cause the MTS3 file to open in the VLC media player application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MTS3 file with the VLC media player application.

Step 3. Update VLC media player to the latest version

The fault may also lie with the VLC media player program, it is possible that MPEG Transport Stream Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the VideoLAN Project Team page and install.

Step 4. Check for the following problems with the MTS3 file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the MTS3 file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the MTS3 file that we want to open. Sometimes virus-infected MTS3 files cannot be recovered, so make a backup in advance.
Older version of MTS3 file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair MTS3 file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file MTS3 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move MTS3 to a different directory.
This problem usually affects more complex files. In this case, the MTS3 file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MTS3 file for a certain period of time. If this does not work either, restart the device.
