The Panasonic AG-DVX100 was a video camera that was released on October 13, 2002. [2] Its 60Hz version was the first consumer digital camcorder capable of recording video at 24 progressive frames per second (FPS), [3] [4] the standard frame rate for 35 mm sound film.
The camera was last updated in 2005 as the DVX100B(E). [5] [6] It is primarily used to record video onto tapes, [7] although third-party developers have created modifications that allow DVX100 cameras to stream raw images directly to a connected laptop. However, one of the main companies known for these modifications, Reel Stream, is no longer in business. [8] [9]
In the Chinese market, the series was branded as "AG-DVC180/A/B," which is otherwise identical to the European PAL model, AG-DVC180E.
The Panasonic AG-DVX100 series includes cameras designed to record video in 24 frames per second (24p), a frame rate that mirrors the operation of traditional film cameras. This 24p format, which employs progressive scan, avoids the interlacing artifacts associated with interlaced formats, making it suitable for motion picture production [10] .
The original AG-DVX100 model recorded in a 4:3 aspect ratio, while the "A" revision introduced widescreen recording capabilities, although users reported that the widescreen output appeared distorted on the built-in monitor. The "B" revision corrected this issue by allowing proper monitoring of the 16:9 aspect ratio. All revisions are equipped with CCD sensors that have a native 4:3 aspect ratio, which results in a loss of vertical resolution when recording in widescreen due to cropping.
The Panasonic AG-DVX100 uses a 3-CCD imaging system that separates light into red, green, and blue channels, each processed by its own CCD sensor. This approach improves image quality and color fidelity compared to single-chip systems. The camera features 410,000-pixel sensors, with approximately 380,000 effective pixels, aligning with standard specifications for professional cameras from its era. This configuration enables it to deliver high-quality images suitable for filmmaking and broadcast use. [11]
The camera can record 24p video using a "telecined" method with 2:3 pulldown for 24P and 2:3:3:2 pulldown for 24PA. It also supports 30p video in progressive segmented frame (PsF) format (25p in PAL) and standard interlaced video at 60i (50i PAL), all stored on MiniDV tape. The DVX100 includes "CineGamma" functionality, which simulates the gamma curve characteristic of film.
The camera includes two XLR audio inputs for professional-grade sound, a 4-pin FireWire port (IEEE 1394) for digital video transfer, and both S-Video and RCA input/output ports for analog connectivity. It also offers manual and servo zoom options, along with a secondary zoom control and record button on the handle, which is particularly useful for low-angle recording.. [12]
Accessories typically used with the DVX100 include batteries (sold separately), lens adapters, matte boxes, optical filters, tripods, geared and fluid heads for smooth movement, follow focus systems, external microphones, and storage cases, allowing for enhanced functionality in various shooting situations.
Many documentaries, independent shorts, and feature movies have been shot with the Panasonic AG-DVX100, including the Sundance Film Festival-winning feature November , The Puffy Chair by the Duplass Brothers, and the Oscar-nominated documentary named Murderball . [13] The documentary "Iraq in Fragments" was also shot with this camera over a two-year period in Iraq. [14] Seasons 1-5 of the popular TV show It's Always Sunny In Philadelphia were also shot with the DVX100. [15] The Man From Earth was shot from only two DVX100 cameras. [16]
The documentary film Ghost Adventures, which won the Grand Jury Prize for Best Documentary Feature from the New York International Independent Film and Video Festival in 2006, was also filmed using the Panasonic AG-DVX100A fitted with on-board lights.
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second. Digital video has many advantages such as easy copying, multicasting, sharing and storage.
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.
Telecine, or TK, is the process of transferring film into video and is performed in a color suite. The term is also used to refer to the equipment used in this post-production process.
Digital8 is a consumer digital recording videocassette for camcorders developed by Sony, and introduced in 1999. It is technically identical to DV cassettes, but uses physical Hi8 tapes instead.
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.
In video technology, 24p refers to a video format that operates at 24 frames per second frame rate with progressive scanning. Originally, 24p was used in the non-linear editing of film-originated material. Today, 24p formats are being increasingly used for aesthetic reasons in image acquisition, delivering film-like motion characteristics. Some vendors advertise 24p products as a cheaper alternative to film acquisition.
The 8mm video format refers informally to three related videocassette formats. These are the original Video8 format, its improved variant Hi8, as well as a more recent digital recording format Digital8. Their user base consisted mainly of amateur camcorder users, although they also saw important use in the professional television production field.
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.
Handycam is a line of camcorders made by Sony and introduced in 1985.
P2 is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004. The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card enclosure. The system includes cameras, decks as drop-in replacements for videotape decks, and a special 5.25-inch computer drive for random-access integration with non-linear editing systems (NLE). The cards can also be used directly where a PC card (PCMCIA) slot is available, as in most older notebook computers, as a normal hard disk drive, although a custom software driver must first be loaded.
Progressive segmented Frame is a scheme designed to acquire, store, modify, and distribute progressive scan video using interlaced equipment.
The Sony HDR-HC1, introduced in mid-2005, is the first consumer HDV camcorder to support 1080i.
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.
The Sony DCR-VX1000 was a DV camcorder released by Sony in 1995. It was the first to use both the MiniDV tape format and three-CCD color processing technology—boasting twice the horizontal resolution of VHS and triple the color bandwidth of single-CCD cameras. It was also the first consumer camcorder with the ability to transfer video information via Firewire to an ordinary Windows or Macintosh computer. Together with the rival Canon XL1 and shorter-lived "budget" three-CCD DV models like the Canon GL1 and Sony DCR-TRV900, the VX1000 revolutionized desktop video production in the late 1990s, delivering quality comparable to then-dominant analog Betacam hardware at a fraction of the cost.
A digital movie camera for digital cinematography is a motion picture camera that captures footage digitally rather than physical film, known as 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.
