For this reason, the format of a clip is defined, that is, a kind of “container”, recognizable by the PC, in which the previous information is attached, in addition to the images. In fact, we should be able to tell the machine where these images are, what type they are, how fast they should be viewed, and in what order. These images alone are not enough to show a movie on our PC. Let’s say we have a series of images that reproduce a movement (we will see later how the capture phase, or video capture, allows this). Film flows, projected images change rapidly, and a motion effect is obtained. A sequence of images is printed on the film, translucent as the negatives of the photographs, which in the projection modify the light beam of the projector, allowing only certain parts to pass through, which will generate an image on the screen.
We all know that you need a screen, a projector, and a movie to get a movie projection. For this reason, we will often use a fitting comparison in the guide: that of motion pictures and the frames that make up the film. To understand the basics of video editing, one must consider display frame theory.
