Film and television post-production is the animation of the finished film or software. For example, adding special effects, adding words, making sounds, etc. So as to form a complete film.
The later software can be divided into plane software, synthesis software, nonlinear editing software and three-dimensional software.
First, edit
1. In order to adjust the relationship between time and space, or expand the space to extend the time, and to emphasize rendering and adjust the rhythm of drama, methods such as multi-use, repeated insertion and transplantation are adopted;
2. The middle of the picture is cut and omitted, and the picture is spliced and extended;
3. Loss, hollowing out, crosstalk and displacement of vocal cords;
4. The method of connecting the lens with action and changing the lens with action illusion; Different editing methods can be adopted for films with different themes and styles.
Second, flashing white light.
In video editing, if you don't use white frame superposition directly, you should add gamma and brightness to the original material, and then superimpose it, so that the bright part of the picture is white first, and then the whole picture is white. It feels like an optical change, not monotonous, and it is best to keep something faintly visible even when it is whitest, that is, without pure white and monochrome.
Third, composition
Except for the serious and powerful performance scenes, the rest of the performance scenes are as asymmetrical as possible. Try to consider composition from the perspective of video editing and connection, and don't be too obsessed with the composition of a single picture. Compared with the aspect ratio of TV, the composition of a single lens is very difficult.
When composing a composition, we usually consider not only the part shown on TV, but also the dynamic three-dimensional composition that changes with time and space.
Fourth, the color of the picture
Try to avoid pure black and pure white, even black, and replace it with very dark red and blue, which will make the overall color more harmonious. The specific tone is determined by the overall tone.
If the film is not bright enough or dark enough, try to avoid the absolute method of bright or dark, and replace it with relative methods such as increasing the area and proportion of bright parts. It is easier to control the local adjustment of the picture by using the curve tool.
For the texture of metallic luster, the main principle is "gold is not afraid of black", that is to say, the production of metallic texture must have dark parts. Try to use moving lights to create flowing highlights instead of reflection maps. You can use negative lights to create dark parts.
Five, the late film and television learning skills.
For ambient sound, it is not necessary to strictly correspond to the production and editing of video images. Generally speaking, the ambient sound enters first and then exits. I feel that it is better to stagger 1-2 tons according to the cutting points of the waveform diagram and the picture. Feel it with your eyes and ears, and don't be too obsessed with keeping consistent with the waveform diagram and tangent point.
Sometimes it is necessary to consider that the sound transmitted to your machine may be slightly delayed compared with the "environmental scene". Pay attention to this point for live radio broadcast and post-production of some large scenes. After all, the speed of light is very different from that of sound.
