An audiovisual sequence is a sequence of images and sound material (" audio ", e.g. music or language) that are matched to them . Most of the time, the images are reproduced at high frequency , giving the impression of a moving image . However, the individual images can also be seen for a longer period of time , as in a “ slide show ” if the viewer is supposed to look at them closely.
Videos can faithfully reproduce an event. In most cases, however, the image and sound material recorded with the camera and microphone is further processed: image sequences are selected and recomposed (see video editing ). Video and audio can be re-coordinated, for example by adding music or spoken comments. Videos can also be created entirely from files already on the computer. In this type of work, each individual audiovisual sequence is analyzed and, if necessary, edited.
