What does the rising and falling grid mean in film and television shooting?

Up and down grid is a technical means in film photography. Changing the normal shooting speed, such as higher than 24 frames per second, is an upgrade; If it is less than 24 frames per second, it is degraded.

Related introduction:

Transmutation is also called "low-speed photography". When the camera shoots at a frequency lower than 24 frames/sec, it is degraded, such as 16 frames/sec, 4 frames/sec, 2 frames/sec, etc. At this time, the speed of the scene displayed on the screen increases exponentially, which is called fast action. Degraded shooting can cause rapid movements, such as rushing and flying clouds, and can also show the scene of flowers blooming and buds unearthed.

The slow-motion effect will change the normal shooting speed, for example, higher than 24 frames per second, which will be upgraded, and the screening effect is slow motion.

Extended data

A shooting method to reduce the running frequency of the camera. Degenerate photography refers to the camera shooting at a frequency of less than 24 frames per second. It can be reduced to 16 frames per second, 8 frames, 2 frames, even several hours, dozens of hours according to different needs, and the frequency remains unchanged at 24 frames per second during screening, and the objects on the screen will present different fast-moving visual effects.

Degraded photography, like upgraded photography, has rich artistic expression, and if it causes some comic effect, it can also be used as a visual means of scientific research.
