Frame Guides
You can choose from seven different frame guides to display on your camera's fold out monitor and
SDI outputs. Frame guides include aspect ratios for various cinema, television and online standards,
plus a rule of thirds composition grid.
Tap the 'frame guide' setting arrow icons to select your desired frame guide. When using Blackmagic
URSA Viewfinder, make sure you have frame guides turned off in your camera's front SDI settings
as the URSA Viewfinder will generate its own frame guides or you will find them doubled up in the
viewfinder display.
HDTV: Displays action and title safe regions of your image within a 1.78:1 aspect ratio compatible
with 16:9 HD television and computer screens.
4:3: Displays the 4:3 aspect ratio compatible with SD television screens, or for to help with framing
when using 2x anamorphic adapters.
2.35:1, 2.39:1 and 2.40:1: Displays the broad widescreen aspect ratio compatible with anamorphic
or flat widescreen cinema presentation. The three widescreen settings differ slightly based on the
changing cinema standards over time. 2.39:1 is one of the most prominent standards in use today.
1.85:1: Displays another common flat widescreen cinema aspect ratio. This ratio is slightly wider than
HDTV 1.78:1 but not as wide as 2.39:1.
Thirds: Displays a grid with two vertical and horizontal lines placed in each third of the image. Thirds
are an extremely powerful tool to help compose your shots. For example, the human eye typically
looks for action near the points where the lines intersect, so it's helpful to frame key points of interest
in these zones. An actor's eyeline is commonly framed along the top third of the screen, so you
can use the top horizontal third to guide your framing. Thirds are also useful to maintain framing
consistency between shots.
Guide Opacity: Aspect ratios are displayed as mattes on the top and bottom of your touchscreen
and fold out monitor. You can adjust the opacity of the matte by adjusting the 'guide opacity' setting.
For example, if you prefer to view your guides as solid mattes, select 100%. Alternatively, if you would
like to view guides at maximum transparency, set the guide opacity to 25%.
