Normal Recording

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”.

Normal Recording and Native Recording

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.

Normal recording (Pull-down recording)

Images at 24P (23.98P: referred to as 24P) are pulled down

in 2:3 mode. Images at 30P (29.97P: referred to as 30P) are pulled down in 2:2 mode and recorded as 59.94i or 59.94P (referred to as 60i and 60P). Images at 25P are recorded as 50i or 50P with 2:2 pulled down. 1080i and 480i support 24PA (2:3:3:2 Advanced Pull down) as well.

AVC-Intra (optional) does not support pull-down recording.

Native recoding

This recording method extracts and records effective frames at the frame rates of the AVC-Intra recording (optional) in 1080i, and DVCPRO HD and AVC-Intra recording (optional) in 720P.

For 720P, it is possible to record images where the length is 2 to 2.5 times longer than the pull-down recording.

Even in Native recording, the rate for outputting camera images and playback images is 59.54 or 50 frames that are pulled down.
