Video jargon can quickly get complicated. But the basics of video are comparatively simple and easily learned, and the rest can follow from that.
'Frame rate' can mean the number of frames per second captured by a camera in burst mode (continuous shooting) or the 'frame rates' offered in video recording.
High frame rates are sought after in stills cameras, particularly for sports photography. In video the frame rate is matched to the playback device, such as a TV or a computer, though high frame rates are used here too, to record frames at a high speed and then play them back at a slower speed for a slow motion effect.
