Software vision mixer

Last updated

In video production, a software vision mixer is a piece of software which is able to switch between various video sources. In some cases, this software is also able to composite (combine) video from various sources. It essentially acts as a software version of a hardware vision mixer.

In contrast to a hardware vision mixer, a software vision mixer allows for a larger number of channels, connection types, and transition effects, and allows for greater flexibility of computer-based content integration, text and graphics overlay, and media programming. Another difference between software and hardware vision mixers is that software mixers are limited by the computer's performance. Software vision mixers are generally less expensive than hardware vision mixers.

A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience. Types of DJs include radio DJs, club DJs, mobile DJs, and turntablists. Originally, the "disc" in "disc jockey" referred to shellac and later vinyl records, but nowadays DJ is used as an all-encompassing term to also describe persons who mix music from other recording media such as cassettes, CDs or digital audio files on a CDJ, controller, or even a laptop. DJs may adopt the title "DJ" in front of their real names, adopted pseudonyms, or stage names.

In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.

<span class="mw-page-title-main">Firmware</span> Low-level computer software

In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems, home and personal-use appliances, computers, and computer peripherals.

Video editing is the post-production and arrangement of video shots. To showcase perfect video editing to the public, video editors must be reasonable and ensure they have a superior understanding of film, television, and other sorts of videography. Video editing structures and presents all video information, including films and television shows, video advertisements and video essays. Video editing has been dramatically democratized in recent years by editing software available for personal computers. Editing video can be difficult and tedious, so several technologies have been produced to aid people in this task. Overall, video editing has a wide variety of styles and applications.

In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program was originally designed for. The term is also used when software/hardware is changed to make them usable in different environments.

A digital audio workstation (DAW) is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.

Neuros Technology was a Chicago, Illinois–based company that produced a number of audio and video devices under the brand name Neuros. Founded by Joe Born in 2001 as a division of Digital Innovations, it previously operated under the name Neuros Audio. Like Digital Innovations, Neuros distinguished itself by its use of open-innovation and crowdsourcing techniques to bring products to market, as well as by its prominent use of open-source software and open-source hardware. In its development model, end users were involved throughout the product development process from reviewing initial concepts to beta testing initial product releases.

Internal security uses type safety instead of hardware memory protection.

DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU-intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU. DXVA 2.0 allows more operations, including video capturing and processing operations, to be hardware-accelerated as well.

<span class="mw-page-title-main">VJing</span> Broad designation for realtime visual performance

VJing is a broad designation for realtime visual performance. Characteristics of VJing are the creation or manipulation of imagery in realtime through technological mediation and for an audience, in synchronization to music. VJing often takes place at events such as concerts, nightclubs, music festivals and sometimes in combination with other performative arts. This results in a live multimedia performance that can include music, actors and dancers. The term VJing became popular in its association with MTV's Video Jockey but its origins date back to the New York club scene of the 1970s. In both situations VJing is the manipulation or selection of visuals, the same way DJing is a selection and manipulation of audio.

In computing, virtualization or virtualisation is the act of creating a virtual version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources.

A video game console emulator is a type of emulator that allows a computing device to emulate a video game console's hardware and play its games on the emulating platform. More often than not, emulators carry additional features that surpass limitations of the original hardware, such as broader controller compatibility, timescale control, easier access to memory modifications, and unlocking of gameplay features. Emulators are also a useful tool in the development process of homebrew demos and the creation of new games for older, discontinued, or rare consoles.
