When using shutter speed, however, the shutter is given an absolute value determined
independently of the frame rate, so the results differ if you change the frame rate.
For example, when shooting at 24 frames per second, a 1/48th of a second shutter speed
produces 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, when 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 camera uses to calculate flicker free
shutter settings.
When shooting under lights, your shutter can affect the visibility of flicker. Your Blackmagic
Pocket Cinema Camera automatically calculates a flicker free shutter value for your current
frame rate and suggests up to three shutter values. 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. Tap ‘50Hz’ or ‘60Hz’ to set
the right frequency for your region.
Characteristics of various light sources may still cause flicker even when using flicker free
shutter values. We recommend performing a test shoot when not using continuous lights.
Image Stabilization
Pocket Cinema Camera 4K has an ‘Image Stabilization’ option to enable or disable image
stabilization on lenses without a physical switch.
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 skips 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.
Display ND Filter As
On Blackmagic Pocket Cinema Camera 6K Pro, you can adjust how the ND filter indicator
displays your NDfilter setting. Each option corresponds to a different camera convention.
Cinematographers typically use ND.number notation, while those familiar with DSLRs or
broadcast cameras may prefer this information in f-stop format, or as a fraction of available light.
These options are available here as ‘number,’ ‘stop,’ and ‘fraction,’ respectively.
