For Mac users, you can now make a better choice to convert your MXF files to better playing and editing. If you have extra video files to be converted at the same time, you can import to the program too. With its built-in video editor, users can freely crop, trim, deinterlace, add subtitles, set special effects to your original MTS source video. You may have seen the default format option in my screenshot which is iPod Nano 4 MP4 file, because I had used the program earlier to convert some flash videos downloaded from YouTube to my iPod. The only thing you have to do is to tick the checkbox of "Merge into one file" next to button "Settings".
