Another main feature of a vision mixer is the transition lever, also called a T-bar or fader bar. This lever, similar to an audio fader, is used to transition between two buses. Note that in a flip-flop mixer, the position of the main transition lever does not indicate which bus is active, since the program bus is always the active or hot bus.
Audio mixing for film and television is a process during the post-production stage of a moving image program by which a multitude of recorded sounds are combined. In the editing process, the source's signal level, frequency content, dynamics, and panoramic position are commonly manipulated and effects added.
In the process of mixing for film or television, a matrix mixer may be used to give the film director, television director or producer a working mix of the project while the mix engineer puts it together. In the recording studio, the same method may be used to give the record producer a different blend during the mixing process.
Photographic fixer is a mixture of chemicals used in the final step in the photographic processing of film or paper. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image. By fixation, the film or paper is ...
Additive mixers add two or more signals, giving out a composite signal that contains the frequency components of each of the source signals.The simplest additive mixers are resistor networks, and thus purely passive, while more complex matrix mixers employ active components such as buffer amplifiers for impedance matching and better isolation.
In filmmaking, audio post-production is the creation and manipulation of audio that is synchronized with a moving picture. This includes, but is often distinguished from production audio, which is the audio recorded as filming occurs.
Sound mixer at work. A production sound mixer, location sound recordist, location sound engineer, or simply sound mixer is the member of a film crew or television crew responsible for recording all sound recording on set during the filmmaking or television production using professional audio equipment, for later inclusion in the finished product, or for reference to be used by the sound ...
That is, the mixer is re-recording sound already recorded elsewhere (the basis of the North American name) after passing it through mixing equipment such as a digital audio workstation and may dub in additional sounds in the process (the basis of the European name). While mixing can be performed in a recording studio or home office, a full-size ...
