The Sony HDR-HC1, introduced in mid-2005 (MSRP US$1999), is the first consumer HDV camcorder to support 1080i.
The CMOS sensor has resolution of 1920x1440 for digital still pictures and captures video at 1440x1080 interlaced, which is the resolution defined for HDV 1080i. The camera may also use the extra pixels for digital image stabilization.
The camcorder can also convert the captured HDV data to DV data for editing the video using non-linear editing systems which do not support HDV or for creating edits which are viewable on non-HDTV television sets.
The HVR-A1 is the prosumer version of the HDR-HC1. It has more manual controls and XLR ports.
Expanded focus lets the user magnify the image temporarily to obtain better manual focus. Expanded focus works in pause mode only; it is not possible to magnify the frame during recording.
A similar feature, named Focus Assist, appeared on the Canon HV20, which was released two years after the HDR-HC1. Focus Assist on Canon camcorders also works only when recording is paused.
Spot meter and Spot focus are possible thanks to a touch-sensitive LCD screen, employed on most modern Sony consumer camcorders.
The user can touch the screen to specify a specific region of the image; the camcorder automatically adjusts focus or exposure according to distance to the object and to illumination of the selected spot.
Depending on a scene, changing focus with Spot Focus can cause focus "breathing" or "hunting", when the subject goes in and out of focus several times before the image stabilizes.
Shot transition allows for a smooth automatic scene transition. In particular, it makes rack focus easy.
Two sets of focus and zoom can be preset and stored in "Store-A" and "Store-B" memory slots. The settings can then be gradually applied from one to another within 4 seconds. The transition time is not adjustable.
Presently, the HDR-HC1 is the only consumer camcorder that offers this feature. Newer Sony consumer models offer Spot Focus mode as a means for rack focus. Changing focus with Spot Focus is faster than with Shot Transition, but is not as reliable because the camera has to search for correct focus each time instead of switching to a stored value.
Cinema effect produces the jerky look usually attributable to a motion picture film. In the world of professional Sony camcorders this effect is known as CineFrame shooting mode.
When Cinema effect is turned on, important manual controls such as shutter speed and aperture are disabled. Implementation of Cinema effect depends on the television system (50 Hz or 60 Hz) used in the target market.
The 50 Hz version of the camcorder, HDR-HC1E, throws away one field from the original interlaced video and doubles another, effectively halving both temporal and spatial resolution. [1] The result can be treated as 25- frame/s progressive video because there is no motion between the two fields of one video frame.
The modification for 60 Hz market records 24- frame/s (more precisely, 23.98- frame/s) video instead, using the process known as 2-3 pulldown. While this recording scheme is widely used in other camcorders that offer 24- frame/s shooting mode, [2] the camera employs an unusual algorithm of generating progressive frames, and then converting them back into video fields. [1]
As Cinema effect is a synthetic method of achieving film-like motion on an interlaced camcorder, it does not improve vertical resolution or light sensitivity. On contrary, spatial resolution is reduced compared to native interlaced recording. The same or better film look effect can be achieved by shooting regular interlaced video and then converting it into pseudo-progressive format with computer software. [3]
Other consumer-grade camcorders are more suitable for film-style recording. In particular, the Canon HV20 and the Canon HV30 camcorders have progressive imaging sensors and are capable of shooting true progressive video preserving spatial resolution and having an added benefit of better light sensitivity compared to interlaced shooting modes.

DV is a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. It includes the recording or cassette formats DV, MiniDV, DVCAM, Digital8, HDV, DVCPro, DVCPro50 and DVCProHD. DV has been used primarily for video recording with camcorders in the amateur and professional sectors.
Interlaced video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the characteristics of the human visual system.
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens.
D-5 is a professional digital video format introduced by Panasonic at 18th International Television Symposium in Montreux in 1993 and released a year later in 1994. Like Sony's D-1 (8-bit), it is an uncompressed digital component system (10-bit), but uses the same half-inch tapes as Panasonic's digital composite D-3 format. A 120 min. D-3 tape will record 60 min. in D-5/D-5 HD mode. D-5 standard definition (SD) decks can be retrofitted to record high definition with the use of an external HD input/output box/decoder. There were native D5 HD decks as well that didn't need an external processor and could record in both SD and HD. High definition conversion on D5 HD decks does not allow for any error correction that exists on standard definition recordings, as the full bandwidth of the tape is required for high definition recording.
HDV is a format for recording of high-definition video on DV videocassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
1080i is a term used in high-definition television (HDTV) and video display technology. It means a video mode with 1080 lines of vertical resolution. The "i" stands for interlaced scanning method. This format was once a standard in HDTV. It was particularly used for broadcast television. This is because it can deliver high-resolution images without needing excessive bandwidth.
HDCAM is a high-definition video digital recording videocassette version of Digital Betacam introduced in 1997 that uses an 8-bit discrete cosine transform (DCT) compressed 3:1:1 recording, in 1080i-compatible down-sampled resolution of 1440×1080, and adding 24p and 23.976 progressive segmented frame (PsF) modes to later models. The HDCAM codec uses rectangular pixels and as such the recorded 1440×1080 content is upsampled to 1920×1080 on playback. The recorded video bit rate is 144 Mbit/s. Audio is also similar, with four channels of AES3 20-bit, 48 kHz digital audio. Like Betacam, HDCAM tapes were produced in small and large cassette sizes; the small cassette uses the same form factor as the original Betamax. The main competitor to HDCAM was the DVCPRO HD format offered by Panasonic, which uses a similar compression scheme and bit rates ranging from 40 Mbit/s to 100 Mbit/s depending on frame rate.
Progressive segmented Frame is a scheme designed to acquire, store, modify, and distribute progressive scan video using interlaced equipment.
AVCHD is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around camcorders.
Sony Corporation produces professional, consumer, and prosumer camcorders such as studio and broadcast, digital cinema cameras, camcorders, pan-tilt-zoom and remote cameras.
MOD and TOD are recording formats for use in digital tapeless camcorders. The formats are comparable to XDCAM EX, HDV and AVCHD.
A digital movie camera for digital cinematography is a motion picture camera that captures footage digitally rather than physical film, which shoots on film stock. Different digital movie cameras output a variety of different acquisition formats. Cameras designed for domestic use have also been used for low-budget independent productions.
The Apple Intermediate Codec is a high-quality 8-bit 4:2:0 video codec used mainly as a less processor-intensive way of working with long-GOP MPEG-2 footage such as HDV. It is recommended for use with all HD workflows in Final Cut Express, iMovie, and until Final Cut Pro version 5. The Apple Intermediate Codec abbreviated AIC is designed by Apple Inc. to be an intermediate format in an HDV and AVCHD workflow. It features high performance and quality, being less processor intensive to work with than other editing formats. Unlike native MPEG-2 based HDV - and similar to the standard-definition DV codec - the Apple Intermediate Codec does not use temporal compression, enabling every frame to be decoded immediately without decoding other frames. As a result of this, the Apple Intermediate Codec takes three to four times more space than HDV.
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD is the highest resolution defined in the Rec. 2020 (UHDTV) standard.
The Canon PowerShot S95 is a high-end 10.0-megapixel compact digital camera announced and released in 2010. It was designed as the successor to the Canon PowerShot S90 in the S series of the Canon PowerShot line of cameras.
A 3D camcorder can record 3D video.
The Panasonic AG-DVX100 was a video camera that released in October 2002. Its 60Hz version was the first consumer-affordable digital camcorder capable of recording video at 24 progressive frames per second.
The Canon EOS 650D, known as the Kiss X6i in Japan or the Rebel T4i in America, is an 18.0 megapixels digital single-lens reflex camera (DSLR), announced by Canon on 8 June 2012. It is the successor of the EOS 600D/Kiss X5/Rebel T3i and is the predecessor of the EOS 700D/Kiss X7i/Rebel T5i. Sales began on 15 June 2012. At introduction, recommended retail prices for the body were US$849.99, £699.99, and €839.99.
