Chapter 3 Recording and Playback Standard and Native Recording This camera is capable both of native recording, when it records video data at the frame rate used by the camera, and is also capable of standard recording or recording 59.94 (50) frames with a pulldown. Standard recording (pull-down recording) Video shot in the 24P mode and in the 30P mode are recorded as 59.94i or 59.94P, with 2:3 pulldown and 2:2 pulldown, respectively. Also, video shot in the 25P mode will be recorded as 50i or 50P, with 2:2 pulldown. The camera can also handle video shot in the 24PA mode (2:3:3:2 advanced pulldown). Note that AVC-Intra does not support pulldown recording.

Standard and Native Recording
This camera is capable both of native recording, when it
records video data at the frame rate used by the camera,
and is also capable of standard recording or recording
59.94 (50) frames with a pulldown.
Standard recording
(pull-down recording)
Video shot in the 24P mode and in the 30P mode are
recorded as 59.94i or 59.94P, with 2:3 pulldown and 2:2
pulldown, respectively.
Also, video shot in the 25P mode will be recorded as 50i or
50P, with 2:2 pulldown.
The camera can also handle video shot in the 24PA mode
(2:3:3:2 advanced pulldown).
Note that AVC-Intra does not support pulldown recording.

Native recording
Native recording extracts only the active frames during
1080i AVC-Intra recording as well as 720P DVCPRO HD
and AVC-Intra recording.
When SYSTEM MODE is set to 720-59.94P, this lengthens
the recording time maximum 2.5 times at 24PN, and
maximum 2 times at 30PN. When SYSTEM MODE is set
to 720-50P, this lengthens the recording time maximum 2
times at 25PN.
Also in native recording, the output of camera video and
playback video is a 59.94 (50) frame rate.

NOTE
• In 24P/24PA, 24PN (native recording) and in 30PN/25PN (native recording) at 720P, the camera starts recording in 5-frame,
4-frame and 2-frame segments, respectively. For this reason, to continue recording clips in a system mode using a different
recording segmentation may break the continuity of the time code.
• The camera uses internal memory for recording, when recording starts as soon as a P2 card is inserted or the camera is
powered up. In this situation, recording cannot be stopped until P2 card recognition ends.
To check P2 card status, press the DISP/MODE CHK button and check the row for SLOT 1 and 2.
• An editing system that supports 24PA (2:3:3:2 advanced pulldown) will enable editing with less quality loss than 24P (2:3
pulldown).
• Record at standard 24P if a 24PA compatible editing system will not be used.
