Have bundles of .mts files captured by your HD camcorder. Now, try to play them back on QuickTime media player or editing them with iMovie, Final Cut Pro, etc, but failed. Is there any solution? Reading the following parts, you should find the way out.
MTS video playback:
MTS file can be directly playable on VLC media player for Mac or Mplayer OSX, for either of them natively accept MTS file. When comes to QuickTime, it isn't compatible with the high-definition MPEG Transport Stream video format. Anyway, if you prefer to watch MTS files with QT media player, you can use the MTS Converter for Mac, then play MTS files in QT and other favorite video players.
MTS video editing:
iMovie can support some AVCHD camcorders. Firstly, check out whether your camcorder can be natively accepted by iMovie'11 at http://help.apple.com/imovie/cameras/en/. In addition, Final Cut Pro can't fully support MTS or M2TS file. You can try your luck to import MTS to FCP. If the MTS/M2TS files grey out when you try to import them to FCP, you may need to convert MTS to FCP compatible file formats like MOV. Alternatively, you can easily edit MTS on Mac with MTS video editor for Mac.
In fact, Doremisoft Mac MTS to MOV Converter is an effective solution for you to easily get rid of all the hassles after converting MTS to MOV, because MOV file format is natively file format supported by QuickTime, iMovie or Final Cut Pro.
