HDV&nbsp;720p format allows recording high definition video (HDV-HD) as well as progressive-scan standard definition video (HDV-SD).<ref name="LWT0278-001B-H">{{cite web|url=http://books.jvcservice.com/Download/903683488/LWT0278-001B-H.pdf|title=JVC GY-HD100/HD-101 instructions|access-date=2010-09-08|archive-date=2022-04-10|archive-url=https://web.archive.org/web/20220410012112/http://books.jvcservice.com/Download/903683488/LWT0278-001B-H.pdf|url-status=dead}}</ref>

HDV-HD closely matches broadcast 720p [[progressive scan]] video standard in terms of scanning type, frame size, aspect ratio and data rate. Earlier HDV&nbsp;720p camcorders could shoot only at 24, 25 and 30 frames per second. Later models offer both film-like (24p, 25p, 30p) and reality-like (50p, 60p) frame rates.

HDV-SD is a mode for recording progressive-scan standard definition video. Such a video is sometimes called ''enhanced definition video'' ([[Enhanced-definition television|EDTV]]), but is considered high definition video in Australia.<ref>{{cite web|url=http://www.cnet.com.au/hd-tv-resolution-explained-339271051.htm|title=HD TV resolution explained|url-status=dead|archive-url=https://web.archive.org/web/20100809075542/http://www.cnet.com.au/hd-tv-resolution-explained-339271051.htm|archive-date=2010-08-09}}</ref> Depending on region, HDV-SD video is recorded either as 576p50 or as 480p60. Like [[DV (video format)#DVCPRO_Progressive|DVCPRO Progressive]], HDV-SD was meant as an intermediate format during the transition time from standard definition to high definition video. Later models of HDV&nbsp;720p camcorders do not record in this mode.

JVC was the only manufacturer of HDV&nbsp;720p camcorders. JVC was the first to release an HDV camcorder, the handheld GR-HD1. Later JVC shifted its HDV development to shoulder-mounted cameras.

A common misconception is that JVC developed a proprietary extension to HDV called [[ProHD]], featuring film-like 24-frame/s progressive recording mode and LPCM audio, for professional use. JVC has clarified that ProHD is not a video recording format, but "an approach for delivering affordable HD products" and a common name for "bandwidth efficient professional HD models".
