HDV Full Progressive Scanning (720p) |
| Industry leading professionals told us that they wanted
a progressive scanning system that would capture and record
the highest quality continuous moving images. ProHD uses
the 720 progressive HDV format and produces crisp, native
HD images that perfectly match today’s digital displays
but which can be easily converted to interlaced without
degradation. |

the essence of film has at last been realized. By capturing
and recording at the film frame rate of 24fps, and offering
extensive user customization of settings like 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 easily transferred

| 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 process. |
