Features and Benefits of XDCAM Professional

Disc Systems

■

Outstanding Picture Quality of

MPEG IMX/DVCAM Format Recording

Sony XDCAM products offer the capability to record*

and play back both MPEG IMX and DVCAM streams**.

Users have the flexibility to select from these formats

according to their picture-quality needs, or to match

their editing-format requirements.

The DVCAM format uses 8-bit digital component

recording with a 5:1 compression ratio and a sampling

rate of 4:1:1 (for NTSC)/4:2:0 (for PAL). The MPEG IMX

format uses 8-bit digital component recording with

MPEG-2 4:2:2P@ML compression at 50, 40, 30 Mb/s,

enabling users to choose the picture quality and

recording time according to their needs.

The XDCAM Series of products provide approximately

85 minutes of DVCAM recording time, and 68, 55, and

45 minutes of MPEG IMX recording at 30, 40, and 50

Mb/s, respectively.

MPEG IMX recording is the ideal choice when you need

higher picture quality, while DVCAM recording offers the

benefit of a longer recording time.

*Recording on the PDW-V1 is available only through the Ethernet or

i.LINK (file access mode) interface.

**The PDW-510/510P camcorder is capable of DVCAM recording

only.

Flexible Metadata Recording

XDCAM products are also capable of recording a variety of metadata,

which provides a huge advantage when searching for data in

subsequent processes. The following are examples of metadata types

that Sony XDCAM Series of products can handle and record.

•

Disc Metadata/Clip Metadata

From acquisition to editing and onto the archiving process, a great amount

of information is associated with the recordings. For example, production

dates, creator names, camera setup parameters, copyright notes, and

memorandums are just a few. With XDCAM products, such information can

be saved together with the AV material on the same disc and be effective-

ly used to improve the entire workflow chain. Using the supplied PDZ-1 soft-

ware allows a variety of data to be added either on a "Disc" or "Individual

Clip" basis in different forms such as "Disc Title","Clip Title",

"Disc ID Number","Comments" or "Clip Status (to indicate OK/NG status)".

Furthermore, the PDZ-1 software has a powerful 'Search' function to easily

locate desired clips by using the registered metadata as text-based

keywords, providing enhanced efficiency in searching material, determining

edit points or retrieving archive materials.

•

Essence Mark Recording

The Essence Mark™ used in Sony XDCAM products is also a very useful form of

metadata, and provide a most effective way of searching for recordings via

thumbnail pictures. Essence Mark can be set during the shoot either manually

or automatically. Thumbnails representing the Essence Mark positions are

generated each time the Essence Mark is set, proving invaluable when

searching for required scenes in subsequent reviewing and editing processes.

• Manual Marking

Each time the 'return' button on the camcorder lens or the 'Shot Mark'

button on the deck is pressed, an Essence Mark is set. After the shoot,

operators can quickly cue to that point simply by selecting its thumbnail

from a list displayed on the LCD screen of the playback device or a

video monitor connected to it. When the PDZ-1 software is used,

operators can define Essence Mark names using desired keywords and

easily set these as user-defined Essence Marks.

• Automatic Marking

XDCAM camcorders can also automatically set an Essence Mark when

particular events are sensed by, or occur within, the camcorder.

For example, the camcorder can be set up to record Essence Mark when the

audio level overshoots, or when there is an abrupt change in video

luminance levels. Since several different types of Essence Marks can exist on

the disc, Sony XDCAM Series of products offer an

easy way of searching through them by type.

•

Others

All XDCAM products are also capable of

recording UMID/Extended UMID (Unique Material

IDentifier) which consists of a globally unique

number or a material number. Another unique

feature that XDCAM products provide is the capability to record any type of

computer file format such as Word, Excel, JPEG, WAV onto the Professional Disc

media, which allows operators to record all files associated with the footage

onto a single disc.
