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.
Battery Display
Your URSA Mini can change the way the battery level indicator displays the remaining charge.
The two settings are ‘percentage’ and ‘voltage.’ When using a battery and plates that support
percentage accurate levels, setting ‘battery display’ to ‘percentage’ will show your battery
power remaining as a percentage.
TIP A list of batteries that support percentage accurate power information is provided
in the ‘mounting batteries’ section of this manual.
If your battery and plate combination does not support percentage accurate readings, the
display will show four bars which empty as the battery depletes.
If this option is set to ‘voltage,’ battery levels will be displayed in volts. We recommend that you
swap the battery as it approaches 12V.
TIP You can also toggle between ‘voltage’ and ‘percentage’ battery displays by
tapping the power icon on the LCD touchscreen.
Timecode Drop Frame
Use the ‘timecode drop frame’ option to use drop frame timecode when using NTSC project
frame rates of 29.97 and 59.94. Drop frame timecode drops a small number of frames from
the timecode at set intervals. This keeps your project timecode accurate despite each
second not containing a whole number of frames at NTSC frame rates.
