There are a large number of camcorders from Sony, Panasonic and Canon record high definition videos with the .mts .m2ts file extension. Both AVCHD MTS and M2TS video files generally use the highly compressed, MPEG-4 AVC/H.264 as native video compression standard, and Dolby Digital (AC-3) or uncompressed PCM linear for audio compression. AVCHD also supports Stereo and multichannel surround (5.1) audio. The video resolutions for AVCHD are varied from 720×480, 720×576, to 1280×720, 1920×1080 and to 1440×1080.

Trouble is, however, the quality MTS file carrying a large size always delivers crisp for playback in many of media players. In particular, some Mac based products like iPad, iPhone even can't recognize it, which makes it necessary to convert the original MTS to MP4 (h.264/mpeg-4) in Mac, a format that has proved to be a common denominator across multiple platforms. So, if you have an AVCHD .mts file from an HD Video camera and want to transfer to your iTunes library or Windows media center or other multimedia apps, for example, converting MTS to MP4 file on Mac / PC is a great fix.

In order to deal with the task, you'll have to get a good end to end solution that enables you to convert your MTS files and export as .mp4 format with high quality retaining. Luckily, there are a variety of MTS converters out there you can go after.
