  • AVCHD compatibility for simultaneous P2HD/AVCHD recording and cross-conversion (optional)
  • Supporting VDCP command in addition to an external VTR control via RS-422A


AVC-Intra Codec

*These figures are for 1080 mode. The AJ-HPD2500 also supports 720p mode.


24PsF Compatible, HD/SD Multi-Format


VariCam Speed Effects


24 Bit*/48 kHz/4 Channel, High-Quality Digital Audio

Advanced Recording Functions Employing Six Card Slots

* 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


Clip Thumbnail Display with Free Clip Sequencing

Edit Control Panel with Jog/Shuttle Dial

Playlist Editor GUI for Intuitive Operation

* No transition settings or effects are available. V fade between events can be set only for audio.

One-Clip Playback and GUI Hold for Easy Manual Data Transmission

The AJ-HPD2500 P2 Deck features easy manual transmission by itself. The one-clip playback function plays resequenced clips one at a time, and the new GUI Hold lets you check the thumbnail image of the next clip by displaying the thumbnail screen onto both the LCD and a monitor during playback. It can also be remote controlled through a parallel, RS-232C or RS-422A interface, for easy operation while checking the thumbnail images on a control desk monitor.

VTR-like Editing


Direct Capture from an External VTR

New Direct Capture from an External VTR

eSATA/USB 2.0 Interface for an External HDD

High-Speed Backup/Restore: Data can be backed up or restored on an eSATA hard disk at up to 4x*1 normal speed. USB 2.0 transfer speed has also been approximately at up to 2x previous model. A Device mode allows a PC (nonlinear editor) to serve as a P2 card drive.
HDD Playback: P2 MXF files on an external hard disk can be displayed at thumbnails and played back at full frame rate.*2 P2 audio playback is uninterrupted by slow hard disk performance, or when vibration temporarily delays data reading.
Playlist Editing: The files on a hard disk can be used for playlists and direct captures in the same way as P2 card data.

*1: For AVC-Intra 100 or DVCPRO HD.
*2: Playback is based on a best-effort basis. Panasonic doesn't guarantee smooth playback without frame drops.


Waveform or Vectorscope Display

Example of a waveform displayThe AJ-HPD2500 has waveform and vectorscope display functions for the playback or input video signal on the LCD monitor. During up-conversion recording, the post-conversion waveform is displayed. It can also displays on Monitor Out (SD)/SDI Out.
* No superimposition will be displayed when the waveform is displayed on an external monitor.

Versatile Playback Functions Meet Diverse Needs

Format Auto Playback: This automatically detects the video format and codec for each video clip to play back and output.
Variable Speed Playback: For slow-motion and double-speed playback
PB Position Selection: This lets you select the playback position when playing from a thumbnail image. You can select from three different options: Previous playback position, thumbnail time code position, or the beginning of the clip.
Repeat Playback: This plays the selected clip (single or multiple) repeatedly.

* Repeat playback of multiple clips is possible only with clips of the same format.


Gigabit Ethernet for FTP Transfers

New Gigabit Ethernet for FTP Transfers

FTP Client Function: This function lets you connect the AJ-HPD2500 to an FTP server to send or receive clips to or from the server. You can upload files from a P2 card or external hard disk to an FTP server, or download files from the server to a P2 card or external hard disk. Files can be uploaded or downloaded easily by using thumbnails. SD/SDHC memory cards can be transferred card by card only.
FTP/Samba Server Function: A PC can upload (by FTP) or download the files to or from a P2 card in an AJ-HPD2500 slot or to or from an external HDD connected to the AJ-HPD2500 via network.*1
HTTP Server Function: You can view thumbnails and metadata from a PC connected to the network.*1
WWW Browser Function: You can access various web pages*2 without a PC. It is also possible to enter authentication information (ID and password) for network access.

*1: SD/SDHC memory cards cannot be accessed.
*2: Some web pages may not be displayed properly due to content. Download functions on web pages cannot be used. Video clips on web pages or linked video files cannot be played.

AES/EBU Digital Audio In/Out

The AJ-HPD2500 comes with eight channels AES/EBU digital audio input and output (BNC) terminals. Since the AJ-HPD2500 supports SDI embedded audio, it can record and play back up to eight channels with 16 bit audio or four channels with 24 bit audio.

Serial Digital Interface

The AJ-HPD2500 has broadcast-standard SDI (HD/SD) input and output terminals. The input signal can be selected with the Video In and Audio In keys on the front panel. Start and stop recording operation can also be linked to a camera recorder.
* AJ-HPD2500 can output superimposition or thumbnails.
* To use linked and automatic recording, the function must be supported by the connected camera recorder. For details, please visit "Other manufacturers' ”AUTO REC” verified Camera list".

AVCHD Recording/Playback and P2HD/AVCHD Conversion (Option)

When equipped with the optional AJ-YCX250G AVCHD codec board, the AJ-HPD2500 can record and play back AVCHD files on an SD/SDHC memory card. It can also convert and copy files between P2HD and AVCHD at normal speed.

AVCHD Recording/Playback and P2HD/AVCHD Conversion (Option)

AVCHD Data Playback Output: AVCHD can be played back on the built-in monitor and output from the HD SDI terminal. This function is useful for using an AVCCAM camera recorder or consumer AVCHD camera recorder.
P2HD/AVCHD Simultaneous Recording: HD SDI input can be recorded in the AVC-Intra/DVCPRO HD format on P2 card and AVCHD format on SD/SDHC card simultaneously.
AVCHD to P2HD Conversion: Clips recorded by an AVCCAM camera recorder can be converted and copied into the AVC-Intra/DVCPRO HD format for use in playlist editing with the AJ-HPD2500 or editing with a P2HD-compatible nonlinear editor.
P2HD to AVCHD Conversion: By copying P2HD clips into low bit rate AVCHD files, it is possible to transfer clips to a server at high speed.

* It is not possible to record in AVCHD format only. The use of DCF Technologies is under license from Multi-Format, Inc.
* The clip metadata will not be copied by conversion copying.

Versatile Remote Control including VDCP Command Support

The AJ-HPD2500 features RS-422A remote that is common in broadcast VTRs (allowing it to be controlled as a player for editing*). It supports VDCP (Video Disk Control Protocol) command in addition to an external VTR control and allows a server-like operation to supply clip-list or be played back by specified clip ID. It also features RS-232C remote for use with PCs and other IT systems, parallel remote, and encoder remote for flexible system configurations.
* Remote control with the RS-422A interface is not possible in AVCHD mode.

Analog Input/Output

The AJ-HPD2500 is equipped with various analog I/Os: Composite Video In, Composite Monitor Out, Audio In/Out (2 channels), Audio Monitor Out (2 channels), Time Code In/Out and Reference Video In (with loop-through).

4U Rack Size

The AJ-HPD2500 has the same height and 4U size as our DVCPRO VTRs and mounts easily into a 19 type rack. It can slip right in as a replacement for an older VTR.
* Mounting adaptor must be purchased separately.


AJ-HPD2500 Input/Output WorkflowVersatile input and output terminals of the AJ-HPD2500 meet a wide range of broadcast station and CATV needs, from line and studio recording to editing, transmitting and archiving. This P2 deck is also equipped with the RS-422A, RS-232C and 25-pin parallel remote control interfaces that are used by conventional VTR systems. It supports VDCP command via RS-422A and server-like operation. Its networking functions and eSATA/USB 2.0 interface further allow the AJ-HPD2500 to serve as the core of a file-based broadcasting system, while allowing continued use of existing tape materials and serving as a flexible add-on to smooth the transition from a tape-based to a file-based system.
