How to Convert MTS to MP4 on Windows and Mac

MTS is the file format used to record and play high-resolution videos. As an enhanced version of the MPEG-2 Transport Stream format, it is used mainly on the latest video cameras and Blu-Ray discs. These files use AVCHD (Advanced Video Coding High Definition) technology and support both 720p and 1080i resolutions.

Files with the .mts extension can usually be opened with applications installed on high-definition video cameras or Blu‑Ray video players, but if you want to play an MTS file on a portable media player or mobile device, you need to convert it to a more flexible format, such as MP4. This format is compatible with almost all media players and devices, so you won’t have any trouble opening or editing with it. This article describes the three main ways to convert MTS to MP4, one of which will surely work for you.

Step 1.Install and Launch the MTS Converter

Download the SuperSpeed Video Converter for Windows or Mac. Run the downloaded file and follow the instructions to install the software on your computer. After the process is complete, launch the program.

Step 2.Choose the MTS Files for Conversion

Click the Add Media button and then Add Video in the upper left corner. In the new window, locate one or more files you want to convert and click Open. All the files will appear in the program window.

Step 3.Specify the Target Format

Open the Video tab at the bottom of the converter interface, select MP4, and choose the preset that best meets your needs. If you want to create an MP4 video for a specific mobile device, click the Devices tab and choose the appropriate preset.

Step 4.Start MTS-to-MP4 Conversion

To choose a destination folder other than the default, click the Directory icon, browse to the folder you need, and click Select Folder. When all the required settings have been specified, you can start converting your files by clicking Convert. When the conversion process is complete, the folder containing the converted videos will open automatically.

Part 2. Use an MTS-to-MP4 Converter That’s Free

Another way to change the format of your video is to use a free conversion program such as VLC Media Player. This approach requires some knowledge of codecs and formats and as such may be challenging for a less experienced user. However, the app is free, so it’s worth checking out.

Step 1.Download and Run the Free Video Converter

Download the freeware installation file from the official VLC website.

Go to the VLC website

Run the file and follow the instructions. When the installation is complete, launch the program.

Step 2.Add the MTS Files to the Program

Launch the program, open the Media menu and select the Convert / Save option.

In the new window, click Add and select the files you want to convert. Then click the Convert / Save button.

Step 3.Select the Output File Format

In the Profile list, select one of the two following profiles: either Video - H.264 + MP3 (MP4) or Video - H.265 + MP3 (MP4). Unfortunately, these are the only options for converting to MP4 supported by the program.

Step 4.Choose the Target Folder and Start the Conversion

If you selected just one file for conversion, click the Browse button in the lower part of the program window, enter a name for the new file and choose the folder where you want to save your file. If you selected multiple files, they will be saved to their original folder under the same names. Although the converted files will have a different extension, there’s still a chance they’ll get mixed up, so you may want to check the box in the bottom left corner to add “-converted” to the names of your converted video files. And finally, click Start to launch the conversion process.

Using freeware may be not easy and can sometimes be buggy, so it’s not always the best way to convert your video files. However, there’s a third option, which is to use an online converter. Read more about this approach below.

Part 3. Convert MTS to MP4 Online

The third option is to convert MTS to MP4 online. You can easily find a website offering free online conversion of most popular video formats. A good example of this is Convertio. However, there are some limitations when it comes to online conversion – in this case, you can only simultaneously convert two files, both of which must be less than 100 MB each. So make sure your videos come in under this ceiling, or you may have to buy a subscription to complete your conversion.

Step 1.Locate an Online Conversion Platform

Open the Convertio main page using the link below.

Go to Convertio website

Step 2.Upload the MTS Files

In the center of the page, choose the source from which you want to import your files: computer, Dropbox, Google Drive, or URL. If you keep your files on your local hard drive, choose the first option and upload them from your computer. To upload files from Dropbox or Google Drive, you need to have an account with those sites. You can also try using the URL for a video shared online, but this approach doesn’t work with all websites.

Step 3.Specify the Target Format

After you’ve uploaded the video, you can set the desired format by clicking the format list and choosing MP4 in the Video section. Convertio also lets you choose from many other output formats, including less common ones like M2TS or MXF.

Step 4.Convert Your Video and Download It to Your Computer

Click Convert and wait until the process is complete. When the conversion is finished, the status will change to Finished. Now you can download the converted files to your computer by clicking the green button.
