VariCam is a brand name associated with the specialized Panasonic video cameras that are mostly used to imitate the look and feel of motion picture cameras.
 They have been used for many feature films. VariCams' main feature is that the framerate can be changed to anywhere between 1 frame per second to 60 frames per second, offering flexibility in creating rapid or slow motion effects.
 Film has traditionally been shot at 24 frames per second, while NTSC video uses 29.97 frames per second, therefore VariCams can be used for high end video production and film production.
