Film special effects principle

In the past, when the digital image was immature, the film was shot with film, and the quality of the film would be reduced when it was cut.

The most serious thing is the production of special effects, which requires linear editing. Linear editing is "a stroke of the whole body", adding special effects through film superposition. In this case, it is necessary to repeatedly expose the copy from beginning to end, and the image quality will plummet.

2 1 century With the maturity of digital imaging technology and CG technology, many Hollywood companies have taken digital pictures, but the price of this equipment (which is not a concept with ordinary civilian DV at all) is unacceptable to many domestic companies, so most domestic films are taken on film, which is why the quality of many Hollywood blockbusters is better than that of domestic films. Digital shooting and nonlinear editing can minimize the influence of post-special effects processing on image quality.
