Slow motion

Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back.

The traditional method for achieving super-slow motion is through high-speed photography, a more sophisticated technique that uses specialized equipment to record fast phenomena, usually for scientific applications.

Some classic subjects of slow-motion include: Slow motion can also be used for artistic effect, to create a romantic or suspenseful aura or to stress a moment in time.

Vsevolod Pudovkin, for instance, used slow motion in a suicide scene in his 1933 film The Deserter, in which a man jumping into a river seems sucked down by the slowly splashing waves.

Cinematographers refer to fast motion as undercranking since it was originally achieved by cranking a handcranked camera slower than normal.

Formally, this effect is referred to as speed ramping and is a process whereby the capture frame rate of the camera changes over time.

Slow-motion is widely used in sport broadcasting and its origins in this domain extend back to the earliest days of television, one example being the European Heavyweight Title in 1939 where Max Schmeling knocked out Adolf Heuser in 71 seconds.

[3] In instant replays, slow motion reviews are now commonly used to show in detail some action (photo finish, goal, ...).

In scientific and technical applications it is often necessary to slow motion by a very large factor, for example to examine the details of a nuclear explosion.

This method is used by all GoPro cameras, Sony RX10/RX100 series cameras (except in the time-limited "super-slow-motion" High Frame Rate (HFR) mode), Apple iPhones with high framerate (slow motion) video recording functionality (starting with the iPhone 5s in late 2013), Sony Xperia flagships since 2014 (Xperia Z2, first Sony flagship with precluded 120fps video recording), LG V series mobile phones and every Samsung Galaxy flagship phone since 2015 (Galaxy S6) for videos with 120 fps or higher.

The menial method saves recorded video files in a stretched way, and also without audio track.

The real-life timespan of the recording (while holding the camera) does not match the length of the video in the output file, but the latter is longer.
