Connecting a P2 Card Camera
A P2 card recorded in a P2 camera recorder plugs directly
into a PC card slot in this unit for immediate access. The P2
card is a semiconductor memory card that Panasonic
developed for professional AV use.
■
AVC-Intra standard feature
The AVC-Intra codec is provided as a standard feature.
An Intra-Frame compression format based on the H.264 video
compression standard makes possible a high compression
rate and high-quality image.
The AVC-Intra codec for this product is compatible with the
following two formats.
AVC-Intra 100: High-quality video supporting full-bit HD
AVC-Intra 50: Low-rate and low-cost operation
■
Built-in up/down/cross converter for output and
up converter for input
The AJ-HPM200 provides a built-in up/down/cross converter
for output as standard. It also up-converts composite and
SD-SDI input signals to record in the same HD format as the
system.
◆
NOTE:
• The cross converter function is not available during up-conversion
recording.
• SD closed caption signals during up-conversion recording are
recorded in the 608 HD (VANC) signal format (59.94 Hz only).
• Closed caption signals are not output during playback or down- and
cross-conversion.
• Nor are closed caption signals output during playback of up-
converted SD signals.
■
Frame rate conversion
Recording input from variable frame-rate cameras at 24PN
(Native), the unit is also capable of playing back cards
recorded at 24 fps and converting the output to 1080/24 PsF.
It can also record input from a variable frame-rate camera at
25PN (Native).
◆
NOTE:
• Do not use cards that have been edited or contain clips shot in
different formats as the loss of management data may prevent
normal playback.
■
Native recording
The unit provides support for native recording, a mode that
records only active frames. This provides longer recording
time when a VariCam, AJ-HPX2000/2100 or AJ-HPX3000 is
connected to the HD-SDI IN connector. Variable frame rate
(VFR) recording becomes possible by connecting a VariCam.
●
Native recording defined
Native recording extracts only the active frames during 1080i
AVC-Intra recording as well as 720P DVCPRO HD and
AVC-Intra recording. At 720P, this lengthens the recording
time 2 to 2.5 times over pull-down recording.
During native recording at a 59.94 Hz or 50 Hz setting in setup
menu No. 25 (SYSTEM FREQ), the unit produces pull-down
output.
■
Thumbnails for managing clips visually
The 9-inch color LCD monitor displays video clips
(thumbnails) stored on a P2 card. The viewer can select the
thumbnails he wants to see and change the order in which
they appear.
Clips can be selected from the thumbnail list for immediate
playback. The list also provides quick access to other clip
management operations such as copying and deleting,
adding shot marks and text memos as well as confirming and
editing clip data.
■
Expanded high-speed hard disk interface
●
High-speed eSATA interface
The unit now supports hard disks using the eSATA interface,
which is faster than the regular USB interface. This interface
provides faster backup of video data on a P2 card to hard disk
and can restore hard disk data to a P2 card.
●
Playback (best effort) and playlist editing of hard disk video
data
Video data on a hard disk can be viewed as thumbnails or a
smooth
*1
video stream. A protective feature ensures a
continuous audio output even if reading performance drops
due to use of a slow hard disk or through interference such as
vibrations.
Playback of hard disk video data
*1
enables editing of video
on a hard disk in the same way as editing video on a P2 card.
Playback
*1
of hard disk video data enables direct editing.
*1: This does not guarantee playback without frame skipping.
