When I was looking for a fast m2ts joiner, I find Aunsoft MTS/M2TS Converter. However, when I have a further look at the official site, I notice that there is another powerful m2ts joiner named Final Mate, which offers the function to merge m2ts files into m2ts file without re-encoding.

Here is my experience with Aunsoft Final Mate to merge m2ts files and the steps to merge AVCHD files from different folders with lossless output.

Import M2TS files to Program for merging into one M2TS Movie.

Aunsoft Final Mate, as a fast m2ts joiner, will help you combine and merge m2ts files from PC or camcorder after imported to the program under the following conditions:
1. The .m2ts files that needed to be combined and merged are located on computer or camcorder. (M2ts files from Blu-ray are not supported.)

2. The .m2ts files are recorded with the same recording mode, or with at least the video codec, resolution (width x height) and video frame rate.


import m2ts files


- For videos from camcorder, just follow the camcorder wizard or click the Wizard button in Camcorder Tab to import videos to program, then drag and drop them to create one movie for lossless merging and exporting.

- For videos from computer, just browse the m2ts files from Resource Tab by selecting a path or clicking Add button to add a new path which stores M2TS files, then drag and drop them to create one movie for lossless merging and exporting.

The best m2ts joiner on PC will display each movie for separate movie ID when you create more than one movie and allows you to export lossless or make a conversion.

To merge m2ts files by creating into one lossless movie.

Just follow the step above to import the videos to Camcorder Tab or Resource Tab.

Then, please clickadd button under Movies Tab to create or add a new movie, this movie generally is a blank movie with nothing. By default, this movie is created for lossless output. After that, you can drag and drop M2TS files with same parameters like resolution, bitrate, framerate, codec, etc from Camcorder Tab or Resource Tab into this blank movie, and then output into only one movie without recoding.


Following is a blank movie for Lossless Output:
