Vision mixers are conceptually similar to audio mixers. They take multiple input sources, apply any desired effects or processing, and provide one or more outputs.

Most vision mixers are based around the preview bus and the program bus, each of which has it’s own monitor....

A vision mixer (also called video switcher, video mixer or production switcher) is a device used to select between several different video sources and in some cases composite (mix) video sources together and add special effects. This is similar to what a mixing console does for audio.

The main purpose of a vision mixer is to create a master output for a real-time video recording or broadcast. Typically vision mixers are used for live events, or any event where multiple sources need to be mixed in real-time. Vision mixers can also be used to create various visual effects, from simple mixes and wipes between sources to advanced composite effects....

In the early days of electronic video production, linear (tape-to-tape) editing was the only way to edit video tapes. Then, in the 1990s, non-linear editing computers became available and opened a whole new world of editing power and flexibility.

Non-linear editing was not welcomed by everyone and many editors resisted the new wave. In addition, early digital video was plagued with performance issues and uncertainty. However, the advantages of non-linear video eventually became so overwhelming that they could not be ignored....

In digital video editing, non-linear editing (NLE) is a method that allows you to access any frame in a digital video clip regardless of sequence in the clip. This method is similar in concept to the “cut and paste” technique used in film editing from the beginning. This method allows you to easily include fades, transitions, and other effects that cannot be achieved with linear editing.

Video and audio data are first captured to hard disks or other digital storage devices. The data is either recorded directly to the storage device or is imported from another source. Once imported they can be edited on a computer using any of a wide range of software....

A blog is basically a journal that is available on the web. The activity of updating a blog is “blogging” and someone who keeps a blog is a “blogger.” Blogs are typically updated daily using software that allows people with little or no technical background to update and maintain the blog. Postings on a blog are almost always arranged in cronological order with the most recent additions featured most prominantly. Blogs are quick and easy to set up.

A web site on the other hand is the official address and location of a web-based business. A website is a collection of related web pages, images, videos or other digital assets that are addressed relative to a common Uniform Resource Locator (URL), often consisting of only the domain name, or the IP address, and the root path (‘/’) in an Internet Protocol-based network. A web site is hosted on at least one web server, accessible via a network such as the Internet or a private local area network....

Linear video editing is the process of selecting, arranging and modifying the images and sound recorded on videotape whether captured by a video camera, generated from a computer graphics program or recorded in a studio. Until the advent of computer-based non-linear editing in the early 1990s “linear video editing” was simply called “video editing.”

Linear Editing is basically mechanical process, in that it employs the use of Camcorders, VCR’s, Edit Controllers, Titlers, and Mixers to perform the edit functions. This editing technique is performed in linear steps, one cut at a time (or a series of programmed cuts) to its conclusion....

Several companies offer a karaoke service on mobile phones, using a Java MIDlet that runs with a text file containing the words and a MIDI file with the music. You can play a song over your phone’s speakerphone and sing along. Better yet, you can record your own voice singing the tune, overlay the recording over the music and send the whole thing to your friends.

A lot of new mobile applications that have started popping up allow people to interact with music stored on their cell phones. Some others let users create their own ringtones. Others allow you to create musical voicemail greetings. Researchers have also developed karaoke games for cell phones in order to boost music database training. ...

Karaoke VCD (Video Compact Disc) are similar to DVD Karaoke discs. They provide words (lyrics) against a live video background. You must have a player capable of playing VCD format to use these discs. While many DVD players are capable of playing VCD’s. VCD cannot be played on a regular CD player.

Many VCD players have a built-in karaoke function. On stereo recordings, one speaker will play the music with the vocal track, and the other speaker will play the music without the vocal track. So, to sing karaoke, users play the music-only track through both speakers....

The first karaoke machine was invented by Daisuke Inoue in Kobe, Japan. He was a popular singer back then and was often asked by customers at Utagoe Kissa, the kind of coffee shops where he played at, for an instrumental version of his songs so they could sing to them at home. Inoue recognized the potential of this kind of market, so that’s when he created the first karaoke machine, which cost 100-yen per each song. In the beginning, Inoue didn’t sell these machines, but only leased them to those interested. At the time many thought it was just a fad since the instrumental tracks kind of took away from the atmosphere of the live show. They were also considered expensive, as at the time, an 100-yen coin could pay for about two lunches.

However, it still became popular and karaoke machines started getting placed in hotels and restaurants. New businesses starting cropping up which dedicated themselves to having rooms with karaoke machines in them. ...

Karaoke video game challenges players to out-sing friends with songs and authentic videos from favorite Hollywood Records artists, TV Series or Movies.

The earliest karaoke-based music video game, called Karaoke Studio, was released for the Nintendo Famicom in 1985, but its limited computing ability made for a short catalog of songs and therefore reduced replay value. As a result, karaoke games were considered little more than collector’s items until they saw release in higher-capacity DVD formats....
