Chapter 3 Recording and Playback — Standard recording and native recording
Standard recording and native recording
You can select between two recording methods: Native recording method that is performed with the shooting frame rate of the camera unchanged, and
the standard recording method where the frame rate is pulled down to 59.94 frames.
Standard recording (Pull-down recording)
Images at 24P are pulled down at a ratio of 2:3, and images at 30P are pulled down at a ratio of 2:2 and recorded at 59.94i or 59.94P.
24PA (2:3:3:2 advanced pull-down) is also supported.
AVC-Intra does not support pull-down recording.

Native recording
This recording method extracts and records valid frames at the shooting frame rates in AVC-Intra recording in 1080i, and DVCPRO HD and AVC-Intra
recording in 720P.
In the case of 720P, recording can be performed 2 to 2.5x longer than that by pull-down recording.
Even in native recording, the rate for outputting camera images and playback images is 59.94 frames that are pulled down.

NOTE
t
Recording starts from the top of a 5-frame cycle for 24P/24PA recording, 4-frame cycle for 24PN (native recording), and 2-frame cycle for
30PN (native recording) in 720P. Therefore, the time code may become non-continuous when recording clips continuously in system modes
with different recording cycles.
t
Just after inserting a P2 card or turning on the power, recording is started using the internal memory of the camera. In this case, recording
cannot be stopped until the P2 card is recognized.
Push the <DISP/MODE CHK> switch towards the <CHK> side and check the P2 card status on the [SLOT1] and [SLOT2] rows displayed on
the viewfinder screen.
t
With 24PA (2:3:3:2 advance pull-down) compatible editing software, editing can be performed with less degradation compared with 24P (2:3
pull-down).
t
When 24PA-compatible editing system is not used, shoot in the standard 24P mode.
