By default, the project and sensor frame rates are matched for a natural playback speed.
However, by tapping the 'off speed frame rate' switch icon in the bottom right hand side of your
camera's 'FPS' menu, you can independently set the sensor frame rate.
To change the sensor frame rate, tap the arrows next to the sensor frame rate indicator in the
lower left of your touchscreen. You can also drag the slider left or right to increase or decrease
the frame rate. Above the slider, you can tap on a common off speed frame rate. These are
based on your current project frame rate.
You can create dynamic and interesting speed effects in DaVinci Resolve by varying the sensor
frame rate for your recorded video. Setting the sensor frame rate higher than your project frame
rate will create slow motion during playback.
Shutter
The 'shutter' indicator displays your shutter speed or shutter angle. By tapping this indicator,
you can manually change your camera's shutter values or configure shutter priority auto
exposure modes. The shutter measurement setting can be used to select whether to display
shutter information as 'shutter speed' or 'shutter angle'. See the 'setup settings' section in this
manual for more information.

Shutter speed defines the level of motion blur in your video, and can be used to compensate
for varying light conditions. The shutter speed setting for natural motion blur, and the settings
available, depend on the frame rate you are using. For example, when shooting at 30p, a 1/60
of a second shutter speed is the equivalent of a 180 degree shutter angle, a very common
setting for film projects. However if you are shooting at 25p, you will need to set the shutter to
1/50 for the same look. As lighting conditions change, or the amount of movement in your scene
increases, you may decide to adjust accordingly.
For natural motion blur you can calculate the shutter speed by doubling your frame rate. So at
30p, set your shutter speed to 1/60 of a second for natural motion blur.
If you need more light on the sensor, you can set the shutter at the slowest setting
corresponding with your frame rate. For example, 1/25 for 25p, or 1/30 for 30p. At the slowest
shutter speed, your motion blur will appear slightly exaggerated.
If you want to reduce the motion blur so action appears sharper and more defined, set the
shutter to a faster speed, such as 1/120 of a second for 30p, or 1/100 of a second for 25p. If you
are familiar with shutter angles, this equates to a shutter angle of 90 degrees.
NOTE When shooting under lights, your shutter can affect the visibility of flicker. Your
Blackmagic Studio Camera will automatically calculate a flicker free shutter value for
your current frame rate. Three suggested flicker free shutter options will appear at the
bottom of the touchscreen display when adjusting your shutter. These shutter values
are affected by mains power frequency in your region. You can set your local power
frequency to 50Hz or 60Hz in the camera's setup menu. See the 'setup settings'
section in this manual for more information.
Tapping the 'shutter' indicator brings up the suggested shutter values along the bottom of the
touchscreen. If you have auto exposure set to 'off,' this screen will show you your currently
