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. For example, shooting with a 60 FPS sensor frame rate and playing back at a

24 FPS project frame rate creates slow motion at less than half the real speed of action.

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 Broadcast G2’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.

Shutter

The ‘Shutter’ indicator displays your shutter speed. By tapping this indicator, you can manually

change your URSA Broadcast G2’s shutter speed or configure shutter priority auto

exposure modes.

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.

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.

It’s worth experimenting with different shutter speeds to see how this setting can provide

different levels of motion blur to your image.

When shooting under lights, your shutter speed can affect the visibility offlicker. Your URSA

Broadcast G2 will automatically calculate flicker free shutter speeds for your current frame rate.

These speeds are affected by mains power frequency in your region. You can set your local

power frequency to 50Hzor60Hz in your URSA Broadcast G2’s setup menu. See the ‘setup

settings’ section in thismanual for moreinformation.
