Sensor Frame Rate
The sensor frame rate sets how many actual frames from the sensor are recorded every
second. This frame rate will affect how fast or slow your video will play back at your set project
frame rate.
With ‘off speed frame rate’ enabled, tap the arrows on either side of the sensor frame rate, move the slider or tap
one of the presets to make adjustments
By default, your URSA Cine’s 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 your sensor frame rate.
To change your 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. Once you release the slider, the sensor frame rate will be selected. Above
the slider, you can select a recommended off speed frame rate that is based on your current
project frame rate.
You can create dynamic and interesting speed effects in your clips by varying the sensor frame
rate. Setting the sensor frame rate higher than your project frame rate willcreate slow motion
during playback. Alternatively, the lower your sensor frame rate, the faster your clips will appear.
The principle is similar to overcranking and undercranking a film camera. Overcranking speeds
up the sensor frame rate so you can stretch out moments in time during playback to enhance
emotion. Undercranking slows down the sensor frame rate so you can increase the action in
fast moving scenes. The creative possibilities are endless and entirely up to you!
For information on the maximum frame rates available for each recording format and codec,
refer to the table in the ‘recording’ section of this manual.
NOTE When ‘off speed frame rate’ is selected your URSA Cine’s audio and video
are no longer synced. This is true even if you set the same project and sensor frame
rate. For this reason, ‘off speed frame rate’ should never be selected if you want to
guarantee audio syncing.
