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 136, “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).
