Videos are made by multiple still photos taken and projected onto a screen, per second. Frame rate or frames per second is the speed at which pictures are shown in a second. For a normal motion picture 24 frames per second is the standard rate. It means 24 pictures are shown within a second, which looks like a video. 24 fps are ideal if you want a cinematic look, 30 fps for TV and live sports and 60 fps is ideal for walking videos, blowing candles etc.
