DIF blocks are the basic units of DV streams and can be stored as computer files in raw form or wrapped in such file formats as Audio Video Interleave ( AVI ), QuickTime ( QT ) and Material Exchange Format ( MXF ).

While low-quality at first, consumer digital video increased rapidly in quality, first with the introduction of playback standards such as MPEG-1 and MPEG-2 ( adopted for use in television transmission and DVD media ), and then the introduction of the DV tape format allowing recording direct to digital data and simplifying the editing process, allowing non-linear editing systems ( NLE ) to be deployed cheaply and widely on desktop computers with no external playback / recording equipment needed.

In addition, the DV specification also supports 16-bit audio at 44. 1 kHz ( 706 kbit / s per channel, 1. 4 Mbit / s stereo ), the same sampling rate used for CD audio.

DVCPRO HD equipment offers backward compatibility with older DV / DVCPRO formats.

Progressive-scan DV camcorders for 60 Hz market record 24-frame / s video using 2-3 pulldown and 30-frame / s video using 2-2 pulldown.

Progressive-scan DV camcorders for 50 Hz market record 25-frame / s video using 2-2 pulldown.

24 frame / s recording is available only on professional DV camcorders and requires pulldown removal if editing at native frame rate is required.

This allowed recording 60 minutes of DV video onto two-hour Video8 / Hi8 cassette.

This container is used primarily on Windows-based computers, though Sony offers two tapeless recorders, the HDD-based HVR-DR60 and the CompactFlash-based HVR-MRC1K, for use with DV / HDV camcorders that can record in DV-AVI format either making a file-based copy of the tape or bypassing tape recording altogether.

* MXF-DV wraps DV video into MXF container, which is presently used on P2-based camcorders ( Panasonic ) and on XDCAM / XDCAM EX camcorders ( Sony ).

and ABC News's Hopkins: 24 / 7 were shot on DV.

Also displays the DV meta-information ( e. g. timecode, date / time, f-stop, shutter speed, gain, white balance etc.

A multimedia computer for non-linear editing of video will usually have a video capture card to capture analog video and / or a FireWire connection to capture digital video from a DV camera, with its video editing software.

With DV came IEEE 1394 ( FireWire / iLink ), a simple and inexpensive way of getting video into and out of computers.

All types of media file formats, from QuickTime DV MPEG AES / EBU MXF through Serial Digital Interface, OMFi, AAF, OpenEXR, to 4k DPX files are supported.

Video compression schemes for Web and DVD make use of a 4: 2: 0 color sampling pattern, and the DV standard uses 4: 1: 1 sampling ratios.

Digital Video ( DV ) adopts a similar method by compressing video frames individually.

There are also more advanced commercial products such as AVS Video Editor, Adobe Premiere Elements, AVID Express DV, CyberLink PowerDirector, Final Cut Pro X, Sony Vegas, Pinnacle Studio, Ulead VideoStudio, Roxio, Nero Vision Easy Media Creator, muvee autoProducer, and Videopad.

Significantly, the MPEG program stream ( MPEG-1 and MPEG-2 ) and DV ( Digital Video ) formats can be concatenated – such a stream is fundamentally a stream of packets.

* DV, a Digital Video tape format

Video is recorded with DV, MPEG-2 Part 2 or MPEG-4 compression schemes.

* DDRs are slowly replacing Consumer: Magnetic tape based DV, Digital8, 8mm Video Format, VHS and MicroMV video tape recorders.

* DV, MiniDV — used in most of today's videotape-based consumer camcorders ; designed for high quality and easy editing ; can also record high-definition data ( HDV ) in MPEG-2 format

Pixlet is a video codec created by Apple and based on wavelets, designed to enable viewing of full resolution, HD movies in real time at low DV data rates.

The data rate for both the audio and video is constant and is roughly the same as DV data rate.

Because HDV has the same data rate as DV, recording time is the same as DV Standard Play.

JVC does market the Digital-S format for professional use ; while the tapes and technology used are superficially similar to D-VHS tapes, the underlying data format is based on the DV codec and the media formulation is drastically different.

Some consumer cameras, in particular DV cameras, can " burn " ( overlay ) the tape timecode onto the composite output.

DVCPRO HD, also known as DVCPRO100 is a high-definition video format that can be thought of as four DV codecs that work in parallel.

Panasonic video recorders that accept medium cassette can play back from and record to medium cassette in different flavors of DVCPRO format ; they will also play small cassettes containing DV or DVCAM recording, via an adapter.

Technically, any DV cassette can record any variant of DV video.

Cassettes labeled as DV indicate recording time of baseline DV ; another number can indicate recording time of Long Play DV.

DV cassettes can come with a memory-in-cassette ( MIC ) low capacity EEPROM memory chip.

With proliferation of tapeless camcorder video recording, DV video can be recorded on optical discs, solid state flash memory cards and hard disk drives and used as computer files.

* Sony XDCAM family of cameras can record DV onto either Professional Disc or SxS memory cards.

* Panasonic DVCPRO HD and AVC-Intra camcorders can record DV ( as well as DVCPRO ) onto P2 cards.

* Most DV and HDV camcorders can feed live DV stream over IEEE 1394 interface to an external file-based recorder.

When video is captured onto a computer it is stored in a container file, which can be either raw DV stream, AVI, WMV or QuickTime.

MXF Info can also analyze MPEG-2, MPEG-4, DV and AES3 essence headers.
