The rest of the stabilization controls let you refine the result. Whenever you adjust any of these
parameters, you must click the Stabilize button again for the effect to be updated.
Stabilization Method: A drop-down menu provides three different options that
determine how the selected clip is analyzed and transformed during stabilization. You
must choose an option first, before clicking the Stabilize button, because the option
you choose changes how the image analysis is performed. If you choose another
option, you click the Stabilize button again to reanalyze the clip.
Perspective: Enables perspective, pan, tilt, zoom, and rotation analysis and
stabilization.
Similarity: Enables pan, tilt, zoom, and rotation analysis and stabilization, for
instances where perspective analysis results in unwanted motion artifacts.
Translation: Enables pan and tilt analysis and stabilization only, for instances where
only X and Y stabilization gives you acceptable results.
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
used for Cropping Ratio, the more DaVinci Resolve will need to zoom into an image to
eliminate these blanked edges.
Cropping Ratio: This value limits how hard the stabilizer tries to stabilize, by dictating
how much blanking or zooming you’re willing to accept in exchange for eliminating
unwanted motion. A value of 1.0 results in no stabilization being applied. Progressively
lower values enable more aggressive stabilization. Changing this value requires you to
click the Stabilize button again to reanalyze the clip.
Smooth: Lets you apply mathematical smoothing to the analyzed data used to stabilize
the clip, allowing camera motion in the shot while eliminating unwanted jittering. Lower
values perform less smoothing, allowing more of the character of the original camera
motion to show through, while higher values smooth the shot more aggressively.
Changing this value requires you to click the Stabilize button again to reanalyze the clip.
Strength: Lets you choose how tightly you want to use stabilization to eliminate motion
from a shot. With a value of 1, stabilization is maximized in an effort to “lock” the shot
in place and eliminate all camera motion. This value is a multiplier. Since some clips
might look more natural with looser stabilization, choosing a number lower than 100
lets a percentage of the original camera motion show through. Negative 1 (-1) disables
stabilization altogether.
Stabilize: Clicking this button on a previously unstabilized clip analyzes the motion
in that clip and applies an initial smoothing effect. Clicking this button on a clip that’s
already been analyzed lets you recalculate a modified stabilization effect after you’ve
adjusted the Camera Lock, Zoom, Cropping Ratio, Smooth, or Strength settings.
Close: Clicking this button takes you back to the overall Camera controls.
TIP: These controls are identical to those found in the Edit page Inspector and the
Color page Tracker palette, and populate the same image processing data. This means
that you can use the Stabilization found on the Cut page, and then use the stabilization
graph and controls found in the Color page to refine the results, if necessary.
