Comprehensive Guide on Merging MTS Files and Converting Formats

MTS, or MPEG Transport Stream, is a high-definition video file format used in AVCHD (Advanced Video Coding High Definition) video clips often captured by brands like Sony, Panasonic, and Canon. However, working with these MTS video files can be complex as not all video editors, media players, or operating systems, including Windows, Mac, and Linux, support this format.

In this article, we delve into how to merge MTS files, convert MTS to other formats like MP4 and AVI, and discuss the best MTS to MP4 converter tools available. We also explore if popular video editing software like Filmora supports MTS files.

How to Convert MTS to MP4 Online

There are numerous online tools that allow you to convert MTS files to the more commonly used MP4 format. These tools work by encoding the MTS file to an output format like MP4 without reducing the video quality. Here's a basic tutorial:

  1. Go to the online video converter's website.
  2. Click on "Upload" or "Add Files" and select the MTS file you want to convert.
  3. Choose MP4 as the output format.
  4. Click on "Convert" or "Start" to begin the process.
  5. Once the conversion is complete, download the MP4 file.

Be aware, these online tools may include a watermark on the converted video, or limit the file size for free users.

Does Filmora Support MTS?

Yes, Wondershare's Filmora, a popular video editor, does support MTS files. You can easily import MTS to Filmora and begin editing, including merging multiple clips, adding subtitles, or applying presets. Filmora provides a beginner-friendly platform for video editing, making it a great tool for those new to the field.

How to Open an MTS File Extension?

You can open MTS files with a variety of media players and video editors. Media players like VLC, Windows Media Player, and Adobe's Media Player support MTS file playback. Moreover, video editing software like Filmora, Adobe Premiere Pro, and others can also open and edit MTS files.

Best MTS to MP4 Converter

  1. Wondershare UniConverter: Supports various formats including MTS, MP4, MKV, AVI, FLV, and more. It allows batch conversions and offers editing tools.

How to Merge MTS Files

Merging MTS files involves combining multiple video clips into a single file. Many of the video converters mentioned above, like Wondershare UniConverter, Any Video Converter, and Movavi Video Converter, also function as a video joiner allowing you to merge MTS files with ease. Just add all your clips, arrange them in the desired order, and select "Merge" or "Join".

Difference Between MTS and AVI

MTS and AVI are both video file formats, but they have key differences. MTS is used for HD camcorders and supports 720p and 1080i HD video formats, making it suitable for high-definition footage. AVI, on the other hand, is a multimedia container format developed by Microsoft. It supports multiple streaming audio and video, but it doesn't handle HD video as efficiently as MTS.

What is the File Format of MTS?

MTS is a file format based on the MPEG-2 transport stream. MTS files contain video, audio, and metadata multiplexed together. MTS and its subset M2TS are the standard file formats for AVCHD, a high-definition digital video format used in HD camcorders from brands like Sony, Panasonic, and Canon.

While dealing with MTS files might seem daunting, with the right tools, you can easily merge, convert, and edit these high-definition video files. Always remember to choose a converter or video editor that suits your needs and maintains the quality of your videos.
