Recording From a Variable Frame-Rate Camera

Recording HD SDI output signals from a variable frame-rate camera as 720/ 23.98p

Combined with a variable frame-rate camera (VariCam: AJ- HDC27 series), the unit makes it possible to record HD SDI (720/ 23.98p over 59.94p) output from the camera as DVCPRO HD or AVC-Intra (requires optional board) 720/23.98p native recording.

1 Connect the camera HD SDI (720/23.98p over 59.94p) output to the SDI IN connector and press the INPUT SELECT button to select SDI.

HD SDI (720/23.98p over 59.94p) output

•To record 720/24p over 60p output from a variable frame-rate camera, set menu No. 25 SYSTEM FREQ to 60-24. No output is made to a monitor video in this mode.

3 Hold down the REC button and the STILL/PAUSE button simultaneously to set the unit to REC PAUSE mode.

4 To start recording, press the STILL/PAUSE button while viewing the video output from the camera HD SDI output.

◆NOTE:

SDI IN connector

•Set setup menu No. 155 AUTO REC to TYPE1 and set the CONTROL switch to REMOTE. The unit will then automatically start and stop recording as the REC and STOP buttons are pressed on the camera.

•SDI is output in the 1080/23.98 PsF video format. Analog video and IEEE1394 are not output.

•The TIME CODE OUT connector does not output a time code and

AUD OUT DLY to ON.

•Set camera TCG to FREE RUN/NDF (non drop frame) mode. A TC/ UB of an SDI input that cannot be properly read cannot be normally recorded.
