A sensor frame rate higher than your project frame rate will
result in slow motion. To ensure your recorded clips play back
at standard speed, set the sensor frame rate to match the
project frame rate.
Video
The 'video' setting uses the REC709 color standard for high definition video. This lets you work faster
by recording directly to the compressed video formats your camera supports, which are compatible
with popular post production software.
Frame Rate
Adjust the 'frame rate' settings by tapping the frame rate arrow icons.
Blackmagic URSA has two frame rate settings; project frame rate and sensor frame rate.
Project Frame Rate
The project frame rate is URSA's recording format frame rate and provides a selection of common
frame rates used in the film and television industry. For example, 23.98 frames per second using
4K ProRes HQ. This frame rate is normally set to match your playback speed used in your post
production workflow.
Your Blackmagic URSA has 8 project frame rate settings including 23.98, 24, 25, 29.97, 30, 50, 59.94
and 60 frames per second.
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. For
standard playback speed, make sure you set your sensor frame rate to match your project frame rate
by selecting 'match' in the sensor frame rate settings.
For information on the maximum frame rates available for each recording format and codec, refer to
the 'maximum sensor frame rates' table in the 'recording' section of this manual.
Variable Frame Rates
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!
