What are the functions of flicker special effects in film and television works?

The smallest unit of film and television editing is the lens, and the lens group needs to switch to the next scene after finishing one scene story. Switching between different scenes is called transition. There are many ways of transition, which are generally divided into skill transition and non-skill special performance. Flash is one of the common ways of skill transition (also called special effects transition).

If a family takes a family photo in a photo studio, let the photographer know? 3, 2, 1, eggplant? When the flash flashes and the shutter is pressed, the family image is left in the negative or memory card. Coupled with the flash effect, the photos developed by the next shot are placed on the desk or desk of a family member, realizing the transformation of time and space.

Show an incoherent narrative

The flash effect can also be used for discontinuous clips of the same scene. In general, the change time of flashing special effects is getting shorter and shorter, which shows that the characters are getting more and more anxious.

Solve the jumping problem

There are many cases of skipping, such as over-axis. In order to ensure the relatively stable position and unified movement direction of the subject in the picture space, the change of aircraft position needs to be scheduled and arranged within the range of 180 degrees on one side of the relationship axis and the movement axis, which violates the axis principle and easily leads to confusion of the audience in the spatial position or direction.

For another example, when shooting a subject with the concept of lens group, the angle change of two adjacent lenses is less than 30 degrees, especially when different scenes are combined, which will bring obvious visual jumping feeling. Generally speaking, editing should follow the principle of fluency and skipping is not allowed. Once the shot material can only jump, the audience can give psychological hints from the audio-visual sense by adding flash special effects and sound effects: have a sense of jumping.

Deformation of whitening: whitening

The process of flashing white is that the clear concrete image in front gradually becomes all white, and then the next clear image gradually appears from all white. Albinism is a variant of albinism, which gradually changes from clear and concrete images to full white, and the change speed is slow, which often indicates death.
