– Camera Lock: Turning on this checkbox disables Cropping Ratio and Smooth, and enables
the stabilizer to focus on eliminating all camera motion from the shot in an effort to create a
locked shot.
– Zoom: When this checkbox is turned on, the image is resized by a large enough percentage
to eliminate the blanking (black edges) that is the result of warping and transforming the image
to eliminate unwanted camera motion. The lower a value Cropping Ratio is set to, the more
DaVinci Resolve will need to zoom into an image to eliminate these blanked edges. If you turn
this off, the image is not zoomed at all, and whatever blanking intrudes into the image is output
along with the image, on the assumption that you’ll have dedicated compositing artists deal with
eliminating this blanking by filling in the missing image data in a more sophisticated manner. You
may also leave this checkbox turned off if you’re planning on animating the Input Sizing Zoom
parameter to dynamically zoom into and out of a shot being stabilized to eliminate blanking only
where it occurs, using only as much zooming as is necessary for each region of the shot.
Using the Classic Stabilizer
The “classic” image stabilizer controls available in DaVinci Resolve version 12.5 and earlier are still
available, simply select “Classic Stabilizer” from the option menu of the Tracker palette. Classic image
stabilization in DaVinci Resolve consists of three steps. First, you analyze the clip. Second, you choose
the Stabilization settings you want to use. Third, you click Stabilize to calculate the result.
When analyzing the clip, you can choose to use either the default Cloud Tracker, which automatically
finds as many trackable points as possible throughout the image and calculates stabilization based on
all of them, or you can use the Point Tracker, which lets you manually place one or more individual
crosshairs on image features that you select. For more information on using the Point Tracker for
window tracking, see Chapter 136, “Motion Tracking Windows.”
The Classic Stabilizer mode of the Tracker palette
As with object tracking, you can choose which aspects of motion to stabilize, but this must be
done before you do the initial image analysis.
Analyze Controls
The Analyze controls automatically scan through the entire clip, identifying trackable features that can
be used to stabilize the shot.
A series of four checkboxes let you turn on and off which axes you’d like to stabilize. These checkboxes
must be selected before you perform an analysis in order to restrict the data that’s generated.
– Pan: Enables horizontal stabilization.
– Tilt: Enables vertical stabilization.
– Zoom: Enables stabilization of size.
– Rotate: Enables stabilization of orientation.
