Native Recording - Panasonic AJ-HPD2500 Operating Instructions Manual

■ Native recording

The unit provides support for native recording, a mode that
records only active frames. This provides longer recording
time when a VariCam, AJ-HPX2000/2100 or AJ-HPX3000 is
connected to the HD-SDI IN connector. Variable frame rate
(VFR) recording becomes possible by connecting a VariCam.
● Native recording defined
Native recording extracts only the active frames during
1080i AVC-Intra recording as well as 720P DVCPRO HD
and AVC-Intra recording. At 720P, this lengthens the
recording time 2 to 2.5 times over pull-down recording.
During native recording at a 59.94 Hz or 50 Hz setting in
setup menu No. 25 (SYSTEM FREQ), the unit produces pull-
down output.
