MOD and TOD are informal names of tapeless video formats used by JVC (MOD and TOD), Panasonic (MOD only) and Canon (MOD only) in some models of digital camcorders. Format names correspond to extensions of video files. Neither JVC nor Panasonic, who pioneered the format, explained meaning of the file extensions, and the formats were never given an official name. Some think that TOD stands for "Transport stream on disk". MOD is used exclusively for standard definition video files, while TOD is used for high definition files.
The first camcorders that used MOD format appeared in 2003. JVC introduced the Everio GZ-MG30, which recorded directly to an internal hard disk drive. Panasonic unveiled the SDR-S100, which recorded to SD cards. The encoding scheme, data rate, frame rate and frame size closely matched parameters of DVD-video.
MOD/TOD video files are nothing but MPEG-2 files with AC3 (MPEG-1 layer2 for TOD files) audio. So .MOD and .TOD files can be easily renamed into .MV2 or .MPG files and then be read easily by most video playback tools.
But those videos, renamed with other extension directly, may be not compatible with your player or editor completely. You may lose some segments unexpectedly. And those crude footages are uncomfortable for viewing without editing and rearrangement. Re-encode your video with a video converter to convert Canon FS mod to mac, you can view them smoothly on QuickTime, iPod, iPhone, Apple TV or edit them to be a real movie with iMovie or Final Cut Pro.
If so, you need to make your Canon FS MOD files usable on your Mac first, Canon FS converter for mac is suitable to all Canon FS series including Canon FS100, Canon FS200, Canon FS300 camcorder etc, which can convert Canon FS to mac, convert FS200 to mac, convert FS300 to mac Mac MOV video format with fast conversion speed and good quality.
Future of MOD and TOD formats
As of 2011, MOD format is still being used in standard definition camcorders manufactured by JVC, Panasonic and Canon. Sony employs MPEG-2 video encoding and Program Stream container in its standard definition camcorders too, but the directory structure is different from MOD, and the media files have conventional MPG extension.
MOD and TOD formats do not allow recording progressive-scan video, neither at "film" rates (24, 25, 30 frames/s) nor at "reality" rates (50, 60 frames/s). This limitation makes MOD and TOD formats suboptimal for online video viewing, because most video hosting websites stream progressive-scan video. On another hand, AVCHD allows recording progressive-scan high-definition video at both "film" and "reality" rates.
