How to shoot slow motion with DV or digital camera?

Slow motion: In general, the switching frequency of film projector and camera is synchronous, that is, 24 shots are taken every second, and 24 shots are also taken every second during screening. At this time, the normal speed appears on the screen. If the photographer speeds up the shooting frequency, for example, 48 shots per second, then under the condition of still 24 shots per second, there will be slow motion on the screen, which is commonly known as "slow motion". When the shooting frequency slows down to less than 24 frames per second, there will be a quick action on the screen during the screening, also called "snapshot".

Under normal circumstances, the camera shoots at normal speed. Some video recorders shoot at double speed (professional high-speed photography), and then they are called slow motion when they play normally.

There are no DV or digital cameras at present. Only film has this function.

But we can still realize the slow motion of ordinary cameras, that is, using post-production software, such as the common "sound shadow" or "premiere". In the later stage, as long as the normal playing time is prolonged, the sound will also change. When doing slow motion, separate the original video and audio, and then dub them separately.
