Serial digital interface (SDI) or HDMI. Some tapeless camcorders are equipped with a FireWire (IEEE-1394) port to ensure compatibility with magnetic tape-based DV and HDV formats. Consumer market Since the consumer market favors ease of use, portability and price, most consumer-grade camcorders emphasize handling and automation over audio and video performance. Most devices with camcorder capability are camera phones or compact digital cameras, in which video is a secondary capability. Some pocket cameras, mobile phones and camcorders are shock-, dust- and waterproof. The consumer camcorder was generally still very expensive throughout the early to mid 1990s but prices compared to the 1980s had halved for an entry level model and fell even further at the turn of the millennium placing them in easier reach of basic income consumers with the addition of available and more easy to obtain credit to spread payments. This market has followed an evolutionary path driven by miniaturization and cost reduction enabled by progress in design and manufacture. Miniaturization reduces the imager's ability to gather light; designers have balanced improvements in sensor sensitivity with size reduction, shrinking the camera imager and optics while maintaining relatively noise-free video in daylight. Indoor or dim-light shooting is generally noisy, and in such conditions artificial lighting is recommended. Mechanical controls cannot shrink below a certain size, and manual camera operation has given way to camera-controlled automation for every shooting parameter (including focus, aperture, shutter speed and color balance). The few models with manual override are menu-driven. Outputs include USB 2.0, Composite and S-Video and IEEE 1394/FireWire (for MiniDV models). The high end of the consumer market emphasizes user control and advanced shooting modes. More-expensive consumer camcorders offer manual exposure control, HDMI output and external audio input, progressive-scan frame rates (24fps, 25fps, 30fps) and higher-quality lenses than basic models. To maximize low-light capability, color reproduction and frame resolution, multi-CCD/CMOS camcorders mimic the 3-element imager design of professional equipment. Field tests have shown that most consumer camcorders (regardless of price) produce noisy video in low light. Before the 21st century, video editing required two recorders and a desktop video workstation to control them. A typical home personal computer can hold several hours of standard-definition video, and is fast enough to edit footage without additional upgrades. Most consumer camcorders are sold with basic video editing software, so users can create their own DVDs or share edited footage online. Since 2006, nearly all camcorders
