As opposed to a fully component setup, some software applications can also provide full audio/video capabilities. Video mixing is done within the computer, which can then be plugged into a video system or splitter, eliminating the need for an external mixer in many cases. The software uses the computer as an all-in-one unit: player, A/V mixer, and monitor. Regular turntables using control cds/vinyl records can directly control the media, and some software suites allow the use of external (MIDI) controllers that emulate turntables, or add additional controls to the software, allowing a more versatile/portable setup or eliminating the added cost of buying turntables or even a mixer. To take advantage of this solution, DVJs copy their DVD tracks, video and HD media onto hard drives, which means less equipment needing to be carried to gigs. This solution is not only more compact, it's less expensive; the software and related external turntable controls can be purchased for a few hundred U.S. dollars and used on any laptop with sufficient computing power and memory, while the Pioneer DVJ players retail for around US$2500. Even a basic component-based setup can cost far more than a top-of-the-line laptop, software, and storage—especially if a sufficient computer already exists and thus doesn't have to be bought new. In addition, with this method, videos can then be manipulated to have more effects, different audio tracks, or even be completely different from the original.
