") camcorder Sony FDR-AX100 with a 1" 20.9MP sensor able to shoot 4K video in 3840x2160 pixels 30fps or 24fps in the XAVC-S format; in standard HD the camcorder can also deliver 60fps. When using the traditional format AVCHD, the camcorder supports 5.1 surround sound from its built-in microphone, this is however not supported in the XAVC-S format. The camera also has a 3-step ND filter switch allowing greater control of how much light can enter the camera for maintaining a shallow depth of field or giving a softer appearance to motion. For one hour video shooting in 4K the camera needs about 32 GB to accommodate a data transfer rate of 50 Mbit/s. The camera's MSRP in the US is US$2,000. In 2015, consumer UHD (3840x2160) camcorders below US$1000 became available. Sony released the FDRAX33, and Panasonic released the HC-WX970K and the HC-VX870. In September 2014 Panasonic announced and claimed 4K Ultra HD Camcorder HC-X1000E as the first conventional camcorder design that can capture up to 60fps at 150 Mbit/s or alternatively standard HD recording at up to 200 Mbit/s in ALL-I mode with MP4, MOV and AVCHD formats all offered depending on the resolution and frame rate.

Lens

The lens is the first component of the light path. Camcorder optics generally have one or more of the following controls: *

, converts light into an electrical signal. The camera lens projects an image onto the imager surface, exposing the photosensitive array to light. This light exposure is converted into an electrical charge. At the end of the timed exposure, the imager converts the accumulated charge into a continuous analog voltage at the imager's output terminals. After the conversion is complete, the photosites reset to start the exposure of the next video frame. In many cases the photosites (per

) are actually reset globally by charging to a fixed voltage, and discharged towards zero individually proportionally to the accumulated light, because it is simpler to manufacture the sensor that way. Most camcorders use a single imaging sensor with integrated colour filters, per pixel, to enable red, green and blue to be sensed, each on their own set of pixels. The individual pixel filters present a significant manufacturing challenge. However some camcorders, even consumer grade devices such as th
JVC GZ-HD3
introduced around 2007, are triple sensor cameras, usually CCD but could be CMOS. In this case the exact alignment of the three sensors so that the red, green and blue components of the video output are correctly aligned, is the manufacturing challenge.


Recorder

The recorder writes the video signal onto a recording medium, such as magnetic videotape. Since the record function involves many signal-processing steps, some distortion and noise historically appeared on the stored video; playback of the stored signal did not have the exact characteristics and detail as a live video feed. All camcorders have a recorder-controlling section, allowing the user to switch the recorder into playback mode for reviewing recorded footage, and an image-control section controlling exposure, focus and

. The image recorded need not be limited to what appeared in the viewfinder. For documenting events (as in law enforcement), the field of view overlays the time and date of the recording along the top and bottom of the image. The police car or constable badge number to which the recorder was given, the car's speed at the time of recording, compass direction and geographical coordinates may also be seen.

such as date/time and technical parameters may be stored in a separate subtitle track. The former allows measuring the exact and undistorted recording time of scenes even if intermittently paused, and the latter may encompass aperture, frames' exposure duration, exposure value, and photosensitivity. On digital camcorders, the video resolution, frame rate, and/or bit rate may be adjustable between higher quality but larger file sizes and lower quality but extended recording time on remaining storage. The image sensor may have a higher resolution than the recorded video, allowing for lossless digital zoom by cropping the area read out from the image sensor. The video player may allow for navigation between individual frames and extraction of still frames from footage to standalone pictures.

is an example of such an imaging tube. Newer analog, and digital camcorders use a solid-state charge-coupled imaging device (CCD) or a CMOS imager. Both are analog detectors, using photodiodes to pass a current proportional to the light striking them. The current is then digitised before being electronically scanned and fed to the imager's output. The main difference between the two devices is how the scanning is done. In the CCD the diodes are sampled simultaneously, and the scan passes the digitised data from one register to the next. In CMOS devices, the diodes are sampled directly by the scanning logic. Digital video storage retains higher-quality video than analog storage, especially on the prosumer and strictly consumer levels. MiniDV storage allows full-resolution video (720x576 for

DVDs may develop DVD rot, losing large chunks of data. An analog recording may be "usable" after its storage media deteriorates severely, but slight media degradation in digital recordings may trigger an "all or nothing" failure; the digital recording will be unplayable without extensive restoration.

s 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 quiet, 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,

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 sold are digital. Tape-based (MiniDV/HDV) camcorders are no longer popular, since tapeless models (with an SD card or internal SSD) cost almost the same but offer greater convenience; video captured on an SD card can be transferred to a computer faster than digital tape. None of the consumer-class camcorders announced at the 2006 International Consumer Electronics Show recorded on tape.


Other devices

Video-capture capability is not confined to camcorders. Mobile phone, Cellphones, Digital single-lens reflex camera, digital single-lens reflex and compact Digital camera, digicams, laptops and personal media players offer video-capture capability, but most multipurpose devices offer less video-capture functionality than an equivalent camcorder. Most lack manual adjustments, audio input, autofocus and zoom. Few capture in standard TV-video formats (480p60, 720p60, 1080i30), recording in either non-TV resolutions (320x240, 640x480) or slower frame rates (15 or 30 fps). A multipurpose device used as a camcorder offers inferior handling, audio and video performance, which limits its utility for extended or adverse shooting situations. The

developed video capability during the early 21st century, reducing sales of low-end camcorders. DSLR cameras with high-definition video were also introduced early in the 21st century. Although they still have the handling and usability deficiencies of other multipurpose devices, HDSLR video offers the shallow depth-of-field and interchangeable lenses lacking in consumer camcorders. Professional video cameras with these capabilities are more expensive than the most expensive video-capable DSLR. In video applications where the DSLR's operational deficiencies can be mitigated, DSLRs such as the Canon EOS 5D Mark II, Canon 5D Mark II provide depth-of-field and optical-perspective control. Combo-cameras combine full-feature still cameras and camcorders in a single unit. The Sanyo Xacti HD1 was the first such unit, combining the features of a 5.1 megapixel still camera with a 720p video recorder with improved handling and utility. Canon and Sony have introduced camcorders with still-photo performance approaching that of a digicam, and Panasonic has introduced a DSLR body with video features approaching that of a camcorder.

Slightly larger than a smartphone, the Flip Video was a basic camcorder with record, zoom, playback and browse buttons and a USB jack for uploading video. The original models recorded at a 640x480-pixel resolution; later models featured HD recording at 1280x720 pixels. The Mino was a smaller Flip Video, with the same features as the standard model.

Interchangeable lenses

Interchangeable-lens camcorders can capture HD video with DSLR lenses and an adapter.


Built-in projector

In 2011, Sony launched its HDR-PJ range of HD camcorders: the HDR-PJ10, 30 and 50. Known as Handycams, they were the first camcorders to incorporate a small image projector on the side of the unit. This feature allows a group of viewers to watch video without a television, a full-size projector or a computer. These camcorders were a huge success and Sony subsequently released further models in this range. Sony's 2014 line up comprises the HDR-PJ240, HDR-PJ330 (entry-level models), HDR-PJ530 (mid-range model) and the HDR-PJ810 (top of the range). Specifications vary by model.


Uses


Media

Camcorders are used by nearly all electronic media, from electronic-news organizations to current-affairs TV productions. In remote locations, camcorders are useful for initial video acquisition; the video is subsequently transmitted electronically to a studio or production center for broadcast. Scheduled events (such as press conferences), where a video infrastructure is readily available or can be deployed in advance, are still covered by studio-type video cameras "tethered" to production trucks.


Home movies

Camcorders often cover weddings, birthdays, graduations, children's growth and other personal events. The rise of the consumer camcorder during the mid- to late 1980s led to the creation of TV shows such as ''America's Funniest Home Videos'', which showcases homemade video footage.


Entertainment

Camcorders are used in the production of low-budget TV shows if the production crew lacks access to more expensive equipment. Movies have been shot entirely on consumer camcorder equipment, including ''The Blair Witch Project'', ''28 Days Later'' and ''Paranormal Activity (film series), Paranormal Activity''. Academic filmmaking programs switched from 16mm film to digital video in the early 2010s, due to the reduced expense and ease of editing of digital media and the increasing scarcity of film stock and equipment. Some camcorder manufacturers cater to this market; Canon (company), Canon and

support 24p (24 fps, progressive scan—the same frame rate as cinema film) video in some high-end models for easy film conversion.


Education

Schools in the developed world increasingly use digital media and digital education. Students use camcorders to record video diaries, make short films and develop multi-media projects across subject boundaries. Teacher evaluation involves a teacher's classroom lessons being recorded for review by officials, especially for questions of teacher tenure. Student camcorder-created material and other digital electronics, digital technology are used in new-teacher preparation courses. The University of Oxford Department of Education Postgraduate Certificate in Education, PGCE programme and NYU's Steinhardt School's Department of Teaching and Learning MAT programme are examples. The USC Rossier School of Education goes further, insisting that all students purchase their own camcorder (or similar) as a prerequisite to their MAT education programs (many of which are delivered online). These programs employ a modified version of Adobe Connect to deliver the courses. Recordings of MAT student work are posted on USC's web portal for evaluation by Faculty (teaching staff), faculty as if they were present in class. Camcorders have allowed USC to decentralize its teacher preparation from Southern California to most American states and abroad; this has increased the number of teachers it can train.
