What is high frame rate (HFR)?

Typically, movie content is produced at 23.98 or 24 fps, and content for TV or streaming distribution may be 25, 29.97, 50, 59.94 or 60 fps.  With the advent of improved camera technology and increases in available bandwidth for storage and transmission, producers are experimenting with higher frame rates such as 100, 119.88 and 120 fps.  Research has shown that motion profiles are smoother at higher frame rates, and such productions lend themselves more readily to conversion applications – since lower frame rates can be more easily interpolated.
