ProHD — Concept of
JVC’s Affordable
HD Solution
1. HDV Full Progressive Scanning (720p)
Industry leading professionals told us that they wanted a full-
frame progressive scanning system that would shoot and
record the highest quality moving continuous images. ProHD
uses the 720/60p progressive HDV format and produces crisp,
native HD images which perfectly match today’s digital
displays and which can be converted easily, without
degradation, to interlaced pictures.
2. Time Code
As a professional system, ProHD products include the facility
to record and display time code. Convenient menu operation
makes it easy to preset time code at the beginning of a tape.
Simply select REC RUN or re-generation mode. User bits are
also available.
3. Highly efficient video compression
To provide the highest quality HD recording, JVC uses the
broadcast industry standard MPEG-2 Main Profile at H-14.
Offering far greater efficiency than frame-bound systems,
ProHD records at data rates at or above commercial broadcast
rates. Recent advancements in non-linear editing have made it
possible to edit ProHD on virtually all popular Non-Linear
systems. Direct
digital transfers through IEEE 1394 ensure there is no loss in
quality throughout the transfer process.
4. Dual recording system
Designed to utilize both DV tape and optional hard disk drives,
ProHD offers the ultimate in media versatility, maximizing
productivity with efficient, economical editing and low-cost
archiving. Now you can safely archive the original tape
cassette and then plug the hard disk straight into your NLE.
Editing can start right away — no need to make dubs or
transfer data.
5. Real 24p
With ProHD, the dream of creating HD video with the essence
of film has at last been realized. By capturing and recording at
the film frame rate of 24fps, and offering extensive user
configurable settings such as exposure, gamma and detail,
ProHD becomes an ideal tool for creative expression. In
addition, native 24p editing is now possible in HD at a low bit
rate of 19Mbps, enabling the creation of EDLs (Edit Decision
Lists) of 24 frame material with compatible Non-Linear Editing
software. For the ultimate expression on the big screen, 24
frame progressive recordings can be transferred easily to 16
mm or 35 mm film.
