10.3.6 Flicker free on/off
Flicker free can be switched off to bypass the digital frame
store and have the video assist output with no delay.
The film camera runs normally at a different speed than
the video assist. E.g. the film camera runs at 24 fps and
the video assist at 25 fps for PAL or 30 fps for NTSC. This
would normally cause different brightness of the individual
video image. To eliminate this so called flicker, video images
are stored at the speed of the film camera into the video
frame storage and recalled in the speed of the video system.
This storage might cause a slight delay, which is not desirable
in some crucial time conditions, e.g. motion control or
shooting of a pop video. Therefore it is possible to switch
the flicker free system off. This will eliminate the delay.
However, flicker will occur in this mode.
Using the Keyboard
• By pressing the FF key Î the flicker free mode alters
between on and off. An illuminated LED shows the
setting flicker free (FF) on ➪ photo.
