Presume you mean MTS files. I use Corel's VideoStudio Ultimate X10 running under Windows 10. I mix MTS and MP4 files from both my camcorder and action cam without any problem and render the final video as a m2t file.
A decent video editor will give you all the options you require, improving the video, adding effects, adding music or a voiceover, chroma key etc.
there are plenty of good editors and tutorials to go with them but the initial learning curve can be steep. I chose VS as it is a very easy editor to use and does all I want.

I have exactly the same question.

Can I ask - is there any loss in quality when exporting in m2t format?


In memoriam
No loss of quality providing the content is not recoded.

TsmuxerGui will do what you want for free other than adding music titles etc Because the content is not recoded it's very fast.

To do that you need video editing software. Like Terfyn suggests. I prefer Magix Video Pro X
