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.
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.
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).
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 from25p) 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-HPX 300Series, the AG-HPX170 Series or the AG-HVX200A Series P2HD camcorders.
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.
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.
The clip thumbnail (image list) display and GUI (graphical user interface) have been completely revamped. You can now select clips for instant playback, deletion, copying or resequencing. This makes it easy to gather and display clips for broadcasting or editing. The new GUI displays the clip properties on the same screen as the clips and clearly shows the source data – with scroll bar, clip count and playback position – at a glance.The thumbnail display can be changed to show any of the images in the clip, and the GUI can be output to a monitor.
Like a broadcast editor, the AJ-HPD2500 is equipped with a jog and shuttle dial. You can shuttle search at up to 100x normal speed in forward or reverse and jog search within a range of -1x to +1x speed. Audio can be monitored up to 10x normal speed.
The playlist function lets you instantly cut edit* up to 100 events or a timeline of up to 24 hours. Operating ease and functions have both been enhanced.
* No transition settings or effects are available. V fade between events can be set only for audio.
The AJ-HPD2500 P2 Deck newly 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 RS422A interface, for easy operation while checking the thumbnail images on a control desk monitor.
The AJ-HPD2500 is equipped with a Direct Capture function. It lets you set IN and OUT points on the player-side preview screen by controlling an external VTR connected via an RS-422A interface, and register or capture (digitization and clip creation) video footage directly onto the editing timeline. This allows quick P2HD production from tape sources in a linear-like fashion.
The 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.
The AJ-HPD2500 comes with 8-channel 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 8 channels.
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.
The AJ-HPD2500 features RS-422A remote that is common in broadcast VTRs (allowing it to be controlled as a player for editing*), 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.
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).
The AJ-HPD2500 has the same height and 4U size as our DVCPRO VTRs and mounts easily into a 19-inch rack. It can slip right in as a replacement for an older VTR.
* Mounting adaptor must be purchased separately.
