User Manual

100 lets a percentage of the original camera motion show through. Zero (0) disables
stabilization altogether. Additionally, you can invert the stabilization by choosing –100,
as described in the section on performing a match move below, and you can use a
negative value either lower or higher than –100 to under or overcompensate when
inverting the stabilization, simulating the effects of parallax where foreground and
background planes move together but at different speeds.
 Smooth: Lets you apply mathematical smoothing to the analyzed data used to stabilize
the clip, and is meant to be used when the Strong parameter is less than 100, allowing
camera motion in the shot while eliminating unwanted wiggling. 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.
 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 repositioning
the image to eliminate unwanted camera motion. The higher a value Smooth Frames
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.
 Tracker Type: A drop-down menu below the Tracker graph lets you choose whether
to use the Cloud Tracker or the Point Tracker. The default Cloud Tracker automatically
finds as many trackable points as possible throughout the image and calculates
stabilization based on all of them. This is fast, but can result in problems if there are
too many prominent subjects in the frame with different vectors of motion. The Point
Tracker, by contrast, lets you manually place one or more individual crosshairs on
image features that you select. This involves more steps, but has the advantage of
letting you choose exactly which features exhibit the motion you’re trying to stabilize.
For more information on using the Point Tracker for window tracking, see Chapter 121,
“Motion Tracking Windows.”
 Stabilize: After you’ve tracked the clip and adjusted the previous two controls, you
need to click Stabilize to calculate the resulting effect of the Strong, Smooth, and Zoom
controls on your clip. Whenever you make changes to the Strong, Smooth, or Zoom
parameters, you need to click Stabilize to recalculate the resulting effect on your clip.
Classic Stabilization With the Cloud Tracker
Classic Image stabilization in DaVinci Resolve is easy, but you need to follow a specific series of
steps for it to be successful.
To stabilize an image:
1 Open the Tracker palette, and choose Stabilizer from the Palette mode drop-down
menu. Select Classic Stabilizer in the option menu. Make sure the Tracker Type drop-
down menu at the bottom right of the Tracker palette is set to Cloud Tracker.
2 Turn off any of the Analyze checkboxes (Pan, Tilt, Zoom, Rotate, Perspective 3D) that
correspond to transform axes you don’t want to smooth.
3 Click the Track Forward button to track the clip forward (or Track Reverse if you’d rather
start from the end of the clip and work backward).
