Shooting

Progressive shooting

The progressive mode can be selected using the PROGRESSIVE item (see page 39) of the setting menu SCENE FILE screen.

30P mode:

Images are shot in the progressive mode at 30 frames per second.

The 30 frames per second images are converted into 60-field interlace signals, and the resulting video signals are output or recorded.

Shift-free, high-quality still pictures can be obtained in this mode.

24P mode:

Images are shot in the progressive mode at 24 frames per second.

The 24 frames per second images are converted into 60-field interlace signals using the regular [2:3] conversion system, and the resulting video signals are output or recorded. Cinema-like images can be obtained in this mode.

When editing images using the conventional 24P [2:3] conversion system, the images of different frames are expanded for the [BoCe] [CoDe] [FoGe] [GoHe] frames in the figure, causing the picture quality to further deteriorate. Under the 24P advanced conversion system, images with minimal picture quality deterioration in the 24P mode can be obtained by weeding out the [BoCe] [FoGe] frames in the figure.

Furthermore, when an editing system that supports the advanced conversion system is used, editing can be performed with minimal picture quality deterioration compared with the 24P mode.

OWhen an editing system that supports the advanced conversion system is not going to be used, shoot in the regular 24P mode.

Bear in mind the following points when shooting in any of the progressive modes.

O The color bars cannot be displayed.

O The gain cannot be controlled. The gain value is controlled using a fixed value.

O The auto focus cannot be controlled.

O When the progressive mode has been selected, the sync signals of the images are temporarily disturbed.

Furthermore, no images are output for approximately 3 seconds.

O A shutter speed setting of 1/50 (OFF) or 1/60 is recommended.

O Since the images are recorded in 5-frame increments when shooting in the 24P mode or 24P advance mode, the timing at which recording starts may be delayed slightly.

O When shooting in the progressive mode using the ATW (Auto Tracking White) function, it will not be possible to adjust the black balance even by pressing the AWB button.
