Converts MOD files for use in QuickTime
Moyea has announced a new conversion utility for camcorder users, the Moyea MOD Converter. The software converts MOD files generated by JVC, Canon or Panasonic digital camcorders to QuickTime, as well as other popular video formats including AVI, DV or MPEG. The results can be played on most Apple hardware, and edited in iMovie, Premiere Pro or Final Cut Pro.
Other features include customizable format settings, and trimming and cropping tools. Users can also run batch conversions, and add advertising, subtitles or company logos to clips. MOD Converter requires Mac OS X 10.4, and is available in a limited free version or a full edition priced at $30.
