Shutter Measurement
On URSA Mini 4.6K and URSA Mini Pro, use this setting to select whether to display shutter
information as ‘shutter angle’ or ‘shutter speed’.
It’s worth mentioning that when using shutter angle, the shutter conforms to the frame rate.
For example, 180 degrees will produce the same motion blur, no matter which frame
rate you use.
When using shutter speed, however, the shutter is given an absolute value determined
independently of the frame rate, so the results will differ if you change the frame rate.
For example, when shooting at 24 frames per second, a 1/48th of a second shutter speed will
produce pleasing motion blur at the equivalent of a 180 degree shutter angle. Change the
frame rate to 48 frames per second and 1/48th of a second shutter speed no longer offers the
same motion blur, now producing the equivalent of a 360 degrees shutter angle. In this
example, once the frame rate is changed to 48 fps, you would also need to change the shutter
speed to 1/96th of a second to produce the same effect as a 180 degree shutter angle.
Flicker Free Shutter Based On
Use this setting to change the mains power frequency your URSA Mini uses to calculate flicker
free shutter settings.
When shooting under lights, your shutter can affect the visibility of flicker. Your URSA Mini will
automatically calculate a flicker free shutter value for your current frame rate and display up to
three suggested shutter values in your heads up display. Shutter values are affected by the
frequency of the local mains power supply used to drive those lights. In most PAL countries, this
frequency is 50Hz, while NTSC countries typically use 60Hz power. Simply tap ‘50Hz’ or ‘60Hz’
to set the right frequency for your region.
NOTE
The characteristics of individual light sources may still cause flicker even when
using flicker free shutter values. We recommend always performing a test shoot when
not using continuous lights.
