REC START/STOP button, REC button on the handle or VTR button at the lens starts recording of video and sound on the
P2 card. A cluster of data that consists of video and sound generated through a shooting action, together with such added
information as meta data, is called a “clip”.
In the unit, the camera’s recording method is selectable
between the Native recording method with the frame rate
unchanged and the normal recording method pulling the
frame rate down to 59.94 or 50 frames.
Images at 24P (23.98: referred to as 24P) are pulled down
in 2:3 mode. Images at 30P (29.97: referred to as 30P) are
pulled down in 2:2 mode and recorded as 59.94i (referred
to as 60i). Images at 25P are recorded as 50i with 2:2
pulled down. 24PA (2:3:3:2 Advanced Pull down) is
supported as well.
AVC-Intra does not support pull-down recording.
Example of 24P Over 60i
This recording method extracts and records effective
frames at the frame rates of the AVC-Intra recording in
1080i.
Even in Native recording, the rate for outputting camera
images and playback images is 59.94i or 50i that are
pulled down.
Example of 1080-24PN (Native)
Notes
z
The recording will start from the top frame of a five-frame
cycle for 24P/24PA recording or a four-frame cycle for
24P native recording, respectively. Therefore, the time
code may be discontinued when recording clips
continuously in different modes during the recording
cycle.
z
Even if a P2 card has just been inserted, or the power
has been just turned on, you can start recording using
the internal memory of camera-recorder. In this case,
recording cannot be stopped until the P2 card is
recognised. If the inserted card is not recognized as a
recordable P2 card, the record in internal memory is
instantly discarded, and the message “CANNOT REC”
message is displayed on the viewfinder. Press the
MODE CHECK button to check P2 card status
(displayed in viewfinder).
