Lens Squeeze Factor
The lens squeeze factor determines the factor that is used for anamorphic desqueeze on the
monitoring outputs when using anamorphic lenses. This value is also written into the metadata of the
clip and allows video players and editing software to automatically desqueeze clips that have been
shot with anamorphic lenses. Frame lines will automatically scale to the selected lens squeeze factor.
Setting the lens squeeze factor for Anamorphic Desqueeze is supported in sensor modes 4.6K 3:2
Open Gate , 3.3K 6:5 and 3K 1:1 .
► Select MENU > Recording > Project Settings > Lens Squeeze Factor and select the lens squeeze
factor.
Following options are available:
1.00 1.25 1.30 1.33 1.50 1.65 1.80 1.85 2.00
Anamorphic desqueeze and the set factor are indicated through the desqueeze icon dis-
played in the Status Info (here: 2.00).
9.2 Sensor Frame Rate
The sensor frame rate determines the amount of frames generated by the sensor in one second. For
sync sound recording, the sensor frame rate matches the project speed. If you record a clip at a higher
sensor frame rate than the project rate, a slow motion effect occurs during playback. Recording at
a lower sensor frame rate results in a time lapse effect. The maximum possible sensor frame rate is
dependent on the set Sensor Mode, Codec and used Compact Drive model (1 TB, 2 TB).
► Select
HOME > FPS to set the sensor frame rate.
► Select a preset from the list or add and select a custom frame rate.
User Buttons FPS Increase / Decrease support to quickly change between FPS presets.
User Button FPS Preset supports to switch to a defined frame rate.
9.3 Shutter
The electronic shutter of the camera can be adjusted from 5° - 356° shutter angle or 1 to 1/8000
seconds (depending on the set frame rate). The preferred shutter unit can be set by the user.
► Select
MENU > System > Shutter Unit .
Following options are available:
Shutter Angle Converts exposure time into the angle of a virtual rotating mirror shutter as in film cameras.
A fixed angle creates varying exposure times with varying frame rates.
