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 must 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.
The other controls let you customize how aggressively the selected clip is stabilized.
Bypass Stabilization: This checkbox lets you turn stabilization off and on to be able to
compare the stabilized and unstabilized image.
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 re-analyze 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: This value is a multiplier that lets you choose how tightly you want to use
the stabilization track to eliminate motion from a shot using the current analysis. With a
value of 1.00, stabilization is maximized. 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. Zero (0) disables stabilization altogether. As an additional
tip, you can invert the stabilization by choosing –1.00 when pasting a stabilization
analysis from another clip to perform a match move based on the overall motion of the
scene, and you can use a negative value either lower or higher than –1.00 to under
or overcompensate when inverting the stabilization, simulating the effects of parallax
where foreground and background planes move together but at different speeds.
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.
