When surfing online at forums and communities about high definition camcorders or Blu-rays, I found more and more people have the puzzles about how to
deinterlace m2ts files to improve and perfect them.

There are two useful tools which can deinterlace m2ts files with ease. Hope it helps!
One: Moyea
MTS Converter (For Windows)
Moyea MTS Converter is a comprehensive mts/m2ts converter, which is powerful to convert or edit mts/m2ts to flv, avi, mkv, 3gp, mov, wmv, divx, xvid and other popular video/audio formats. One of its unique features is to deinterlace m2ts for good image/picture effect. If you need to use the function, just follow the below: “Add” m2ts files – “Edit” – “Effect” – “Deinterlacing”. After that, you will get the m2ts files without interlaces.
Two: Moyea
MTS Converter for MacAs for Mac users, Moyea MTS Converter for Mac is a perfect alternative tool to do the same as Moyea MTS Converter on Windows. Besides mts/m2ts conversion, it also supports other wonderful editing options, like trimming/splitting, cropping/cutting, etc.
