ProHD — Concept of JVC’s Affordable HDSolution
1. HDV Full Progressive Scanning (720p)
Industry leading professionals told us that they wanted a
progressive scanning system that would shoot and record the
highest quality continuous moving images. ProHD uses the 720
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 scanning
pictures.
2. Time Code
As a professional system, ProHD products include the facility to
record and display timecode. 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 HL-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 the quality is
maintained throughout the transfer process.
4. Dual recording system
Designed to utilise both DV tape and hard disk drives, ProHD
offers the ultimate in media versatility, maximising 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 realised. 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 important tool for creative expression. For the ultimate
expression on the big screen, 24 frame progressive recordings
can be transferred easily to 16 mm or 35 mm film.
