Example of Connections in 23.98/24/
29.97/25 Hz Mode
When playing back a card recorded at a frame rate of 24 fps
(25 fps), the unit is capable of converting the output to 1080/
24 PsF (1080/25 PsF or 1080/50i) for recording on an AJ-
HD3700 series.
Shown in the figure below is an example of deck-to-deck
connections. Input the following reference signals as REF input.
AJ-HPD2500
(source rear panel)
Reference signal
23.98 Hz mode: HD REF 47.95 Hz (interlace)
24 Hz mode: HD REF 48 Hz (interlace)
25 Hz (HD)/50 Hz (HD) mode: HD REF 50 Hz (interlace) or SD REF 50 Hz (interlace)
29.97 Hz mode: HD REF 59.94 Hz (interlace) or SD REF 59.94 Hz (interlace)

◆ NOTE:
• Synchronization with REF input at start of playback in 23.98/24 Hz
mode may distort the first number of frames and mute sound output.
Note that movement in HD SD video output at speeds other than 1x
may look unnatural.

Video monitor
• In 23.98 Hz mode, the composite monitor video signal output by the
ANALOG COMPOSITE MONITOR OUT connector does not include
VITC signals.
• For details on compatible input and output formats, refer to "List of
Compatible Input and Output Formats" (page 209).
• In 23.98/24 Hz mode, HD SDI output is delayed by approximately 2
frames relative to analog VIDEO output.
• Composite monitor video is not output in 24 Hz mode.
Example of Connections for Remote
Control
These connections make it possible to send commands via
the remote control connector to enable remote control of
external devices. The playlist mode allows control of the
source device to capture video directly to the timeline.
Shown in the figure below is an example of deck-to-deck
connections.
Set the CONTROL switch on the front panel of the external
device to REMOTE.
Press the REMOTE button on this unit to turn the button off.
