Your shutter setting can also affect the visibility of flicker when shooting under lights, so your
URSA Broadcast G2 can automatically calculate and display flicker free shutter options for your
current frame rate. Note that the characteristics of individual light sources may still cause flicker
even when using flicker free values. For more information, refer to the ‘touchscreen
controls’ section.
If you have opened up your shutter to the slowest shutter speed or widest shutter angle
possible and are still seeing flicker in recorded footage, you may need to consider using
different light sources for your scene or look into using a faster lens.
Maximum Sensor Frame Rates and Data Rates
The table below contains available codecs and resolutions with their maximum sensor frame
rates and data rates. It should be noted that the references to Blackmagic RAW, ProRes 444
and ProRes 422 are references to all of the supported variants within each particular codec.
Because of the data rates required for recording high resolutions in slow motion you will need
to choose a fast CFast card, USB-C flash disk or SSD. Refer to the ‘storage media’ section for
more information.
TIP You can test the speed your card can sustain by switching on the ‘stop recording’
option from the ‘if card drops frame’ settings menu and recording a test clip. This
will allow you to test how long you can shoot at a particular frame rate in any given
resolution. If the card stops recording too quickly, moving to the next available
compression setting or resolution will lower the data rate and make it easier for
the card to maintain.
