Audiovisual sequence

This includes a certain image of synchronous sound sequence: With proper reproduction of the image sequence is a certain sound always played simultaneously with a certain image.

The seeing and hearing viewers can perceive a total of a moving picture and to hear the same sound sequence (eg, music or voice).

This allows information to be passed.

Through cameras and microphones at the site of an event, for example, information can be recorded as an audiovisual sequence that are similar to those as they would perceive a person's eyes and ears, which is located at the location of the cameras and microphones. When playing such an audiovisual sequence arise in the eyes and ears of the recipients in turn similar sensations like a man who had stood in the place of the camera and microphone.
It is also possible to create by drafting or editing audio-visual sequences derived not from the location of an event, but were artificially created or recombined. The viewer of such a sequence can sometimes have a similar impression as the witness of an event that has it but that never actually existed.

Audiovisual sequences can be transported or stored on different media, for example,

chemical paths on films or on
magnetic paths on magnetic tapes ( video ), more recently, increasingly, on
digital media such as DVDs or

Streaming video , so as a stream of data (both wired and radio via cable-free).
An audiovisual sequence can include anything, such as a

News program, a specific
time section of it, not a recorded
It has picture and sound of a surveillance camera with microphone, or even a
unintentionally by a technical malfunction caused a sequence of images and sounds.
The term film is used only for named and recorded audio-visual sequences, such as for feature films , documentaries or animated films .

To low beam (English fade in , fade-out ) are cinematic design elements that are often used to scenes clearly delineate. While a Fade in the beginning of a sequence indicates the end of which is marked by a fade-out. Fading in and comply with the curtain in theater .
Both techniques are often used together and serve to build a narrative structure. They enable both temporal and local jumps are illustrated.As artificial effects , but they interrupt the narrative flow and thereby a film one can episodic nature lend. This can reduce the distance between audience and story increase.

In addition to speaking at the brightening of the "black" image at the beginning of film and the darkening of the image at its end by Fade inand fade out . Variations of up-and fade-out, for example, the white visor, is performed at the same with a different color / contrast.

When the movie camera for this purpose is usually the variable shutter used, which allows the adjustment of the light sector, and thus the exposure time during the recording. Rare is the lens aperture in use, because they can not usually very close and because the change indepth may be disruptive. However, there are special lenses, the iris can be closed completely with the help of an additional lamella.

In professional fields, the fading in and out are usually the lab left.

By combining both techniques in conjunction with film rewind results in a transition .
