HDV-HD closely matches broadcast 720p progressive scan video standard in terms of scanning type, frame size, aspect ratio and data rate. HDV 720p format allows recording high definition video (HDV-HD) as well as progressive-scan standard definition video (HDV-SD). The HDV 1080i defines optional progressive recording modes, and in recent publications is sometimes called HDV 1080 or 1080-line HDV as progressive 1080-line recording becomes commonplace. The latter is preferred by Sony and Canon and is sometimes referred to as HDV2. The former is used by JVC and is informally known as HDV1. Two major versions of HDV are HDV 720p and HDV 1080i. At the coded bitrate of 384 kbit/s, MPEG-1 Layer 2 audio is regarded as perceptually lossless. In contrast to the video, HDV audio bitrate is relatively generous.

The relatively low video data rate can cause bit rate starvation in scenes that have much fine detail, rapid movement or other complex activity like flashing lights, and may result in visible artifacts, such as blockiness and blurring. The data rate for both the audio and video is constant and is roughly the same as DV data rate. The compressed audio and video are multiplexed into an MPEG-2 transport stream, which is typically recorded onto magnetic tape, but can also be stored in a computer file. Stereo audio is encoded with the MPEG-1 Layer 2 compression scheme. Video is encoded with the H.262/MPEG-2 Part 2 compression scheme, using 8-bit chroma and luma samples with 4:2:0 chroma subsampling. HDV video and audio are encoded in digital form, using lossy inter frame compression. HDV and HDV logo are trademarks of JVC and Sony.

The four companies formed the HDV Consortium in September 2003.Ĭonceived as an affordable high definition format for digital camcorders, HDV quickly caught on with many amateur and professional videographers due to its low cost, portability, and image quality acceptable for many professional productions. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. As a result the HVR-Z1E incorporates more than 40 extra functions over the consumer camcorder HDR-FX1E to help support you and your production needs.HDV is a format for recording of high-definition video on DV videocassette tape.
