For the conversion of MTS files to MP4 you can use Handbrake.

Mac OS X 10.7 and later




Make sure the conversion is in high quality. The same  as described under Format factory


Since this program does not have a merge/join function it is not preferable to use.
In stead, you can use Avidemux




Because we do not have a Mac at our disposal, We cannot explain in detail how the program works.

So it is up to you to understand the details of the program and experiment with the software.
