"The introduction of HDTV production necessitated a medium for storing high resolution video information. In 1997, Sony bumped its Betacam series up to HD with the HDCAM standard and its higher-end cousin HDCAM SR. Panasonic's competing format for cameras was based on DVCPRO and called DVCPRO HD. For VTR and archive use, Panasonic expanded the D5 specification to store compressed HD streams and called it D5 HD."
It's a geat pity that there are no analog video formats that are capable of,e.g. 1080p at 100fps, the nearest I've ever heard of are formats like Hi-Vision laserdisc and W-VHS for Japan's analog 1125 line standard (the highest resolution ever achieved on analog broadcast TV). I've also been wondering why so many movies are still filmed at the old-fashoned 24fps if most of their viewers watch them on DVD and Video, which typically operate at modern, higher framerates. On photographic film, I can see a good reason, I saves film. I have never understood why even digital movies still stick to this framerate, though or why electronic recording is more "traditional" in the audio domain than in the visual domain, if 1000+ line TV was technically possible even way back in the 1940s, why didn't some Analog High definition video standard replace cine-film long ago?203.26.37.35
- Agreed, 24 fps makes sense as a legacy framerate but its limitations are obvious, particularly with motion.
- Don't forget the old French 819-line system, which was near-HDTV, but B/W only. ProhibitOnions 16:46, 26 March 2006 (UTC)
[edit] First paragraph
This could use a rewrite. The first sentence implies that it's only for recording from television, when it can of course be used to record from other sources (such as video cameras), are a popular format for commerical pre-recording materal, and can contain other content such as films.
It also gets fairly technical immediately after the first sentence. Pimlottc 12:37, 26 March 2006 (UTC)
