AVC-Intra Codec
The new AVC-Intra codec further
advances HD production. It
complies with the MPEG-4 AVC/H.264 international standard based on
advanced image compression technology, and offers both superb image
quality and highly efficient compression. It uses an intra-frame compression
system to bring important advantages to professional editing. The
AJ-HPD2500 can record in AVC-Intra 100 for maximum picture quality or in
AVC-Intra 50, which adopts a lower bit rate, for versatile operation. It also
supports DVCPRO HD codec.
• AVC-Intra 100: With the same bit rate as DVCPRO HD, this mode
supports full 10 bit recording with 1920 x 1080* pixels. It captures master-
quality video for high-end video production.
• AVC-Intra 50: This mode delivers video quality very similar to DVCPRO HD
with 1440 x 1080* pixels, yet is able to do so at bit rates usually associated
with standard definition (e.g., DVCPRO 50). AVC-Intra 50's lower bit rate
doubles the recording time and cuts the transferring time in half.
* These figures are for 1080i/p mode. The AJ-HPD2500 also supports 720p mode.
Up-/Down-/Cross-Conversion
The AJ-HPD2500 can convert up or down between HD and SD or cross-
convert between 720p and 1080i during playback. It can also up-convert SD
input for recording in HD, and it features an aspect conversion function.
* The cross-converter function is disabled during up-conversion recording. During up-conversion
recording, the closed caption signal in the SD signal is recorded as a 608-format HD (VANC) signal
(59.94 Hz only). The closed caption signal in the SD signal is not output during up-conversion, down-
conversion or cross-conversion playback.
24PsF Compatible, HD/SD Multi-Format
Supporting a wide range of HD formats, such as 1080p, 1080i and 720p, the
AJ-HPD2500 can be switched between 59.94 Hz and 50 Hz to adapt to the
world's HD broadcasting formats. The AJ-HPD2500 supports 1080/24p
(30p/25p) native recording and playback with the AVC-Intra codec. In HD SDI
mode, it supports 1080/24PsF input/output for use in high-end movie
production. It also supports SD, and multi-codec recording (DVCPRO 50,
DVCPRO, DV) is possible in both NTSC (480i) and PAL (576i).
VariCam Speed Effects
The AJ-HPD2500 can extract active frames from VFR (variable frame rate)
signals output by a VariCam and record them in 720/24p (30p/25p). The
AJ-HPD2500 can also provide VariCam-like 60p pull-down output (50p from
25p) by playing back a video clip in a P2 card recorded in native 720/24p
(30p/25p) by the AJ-HPX2700, the AG-HPX500 Series, the AG-HPX300
Series, the AG-HPX170 Series or the AG-HVX200A Series P2HD camcorders.
16 Bit/48 kHz/8 Channel, High-Quality Digital Audio
The AJ-HPD2500 can record and play back high-quality, 16 bit/48 kHz digital
audio. It comes with 8 channel AES/EBU digital audio input and output
(BNC) terminals. This allows the connection of digital audio equipment with
a 48 kHz sampling rate or digital VTR. Since the AJ-HPD2500 supports SDI
embedded audio, it can record and play back up to 8 channels. For SD
format, the AJ-HPD2500 records and plays 4 channel audio with all DVCPRO
50/DVCPRO/DV codecs.
Advanced Recording Functions Employing Six Card Slots
The P2 card offers a large capacity of up to 64 GB* in a small, lightweight
package. Its rugged design withstands even harsh professional use.
The AJ-HPD2500 comes with six P2 card slots. It enables continuous
recording for up to 12 hours onto six cards (using the AVC-Intra 50 codec),
for extended HD recording and transmission.
• Hot-Swap Recording: Endless recording can be achieved by replacing
cards while recording. It newly supports to select the recording slot while
recording.
• New Auto Recording: This new function automatically starts recording by
SDI signal input.
• Loop Recording: Endless recording sequentially overwrites the oldest data
with new data. When used with cameras for time-sensitive information
gathering like weather news, the loop recording function holds the latest
video data for a predetermined time period.
* Total card capacity includes space for data management such as system data; therefore, the actual
usable area is less than the capacity indicated on the card.
Text Memo, Shot Marker and Metadata
• Text Memo: When recording or previewing a clip, you can attach a memo
(similar to a bookmark) at a desired location (up to 100 locations on a frame
basis). The simplified editing function lets you copy a segment between
memos and create a new clip. Text information can be added to a memo.
• Shot Marker: During or after recording, you can mark each clip with OK,
NG or another designation.
• Clip Metadata: This function lets you browse and edit metadata, such as
the name of the camera operator and reporter, shooting location and text
memos. Text data can also be easily inserted by connecting a USB or
software keyboard, and metadata files can be uploaded from an SD/SDHC
card.
