11.5 LCD Menu defaults
The Panavision Defaults for the LCD Menu items are:
COLOR BAR SW – Turn bars on or off.
The type of COLOR BAR is selected on VF1 menu page M9, see 26.3
SHUTTER SPEED – controls the electronic shutter and
determines the effective exposure time for each frame.
- SHUTTER SPEED offers the following degrees:
270, 180, 173 (172,8), 144, 90, 69, 35, 17, 9 and ECS
- ECS is used to select other shutter speeds defined by ECS FREQ
setting below.
As with film cameras, higher shutter numbers imply more motion
blur for each frame and therefore less perceived strobing, as well as
longer exposure times for each frame and therefore more exposure.
ECS FREQ – This allows you to set shutter angles from 3.8 to 360.0
degrees in 1/10 degree increments.
- At 360 degrees the camera is exposed for the entire duration of
the frame time. At 24 fps, the exposure is 1/24
th
of a second, a full
stop more than 180 degree shutter exposure time of 1/48
th
of a
second.
ECS is also used to eliminate horizontal bars when shooting CRT
monitors in a locked-off shot. ECS stands for Extended Clear Scan,
a trademark Sony video term
MASTER GAIN – changes the amplification of the signal. More gain
means more exposure but also more video noise.
- The gain options are: -0.5, 0, 0.5, 1.0, 1.5 and 2.0 stops
Panavision recommends that you shoot tests of a range of Gain
options to see what works for you.
