To manually reposition or track a window that can’t be interpolated properly:
1. Open the Object Tracking Controls of the Viewer page, and click Key Frame to change
the tracking mode.
2. Move the playhead to the last frame of the clip that was successfully tracked.
3. Move the playhead frame by frame, adjusting the position of the window at each frame
to move along with the feature that you’re trying to track.
Continue adjusting the window frame by frame until you’ve reached the end of the
clip, or reached the end of the gap in tracking data so that the window is now at the
beginning of the next successfully tracked section of the clip.
This technique may not be fun, but it’ll get the job done in a pinch.
Image Stabilization
The Image Stabilization option of the Object Tracking controls lets you smooth out or even steady
unwanted camera motion within a clip. The analysis is performed in such a way as to preserve the motion
of individual subjects within the frame, as well as the overall direction of desirable camera motion, while
correcting for unsteadiness.
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.
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.
Stabilization Controls
There are three controls in the Stabilization group:
Smooth Frames slider: Lets you choose how much stabilization to apply to the clip.
Lower values allow more of the original camera motion to show
through, while higher values lock the shot off more aggressively.
0 disables stabilization altogether.
Stabilization Zoom checkbox: When turned on, the image is resized by a large enough
percentage to eliminate the black edges that are the result of
repositioning the image in order to eliminate unwanted camera
motion. The higher a value Smooth Frames is set to, the more
Resolve will need to zoom into an image to eliminate these
black bars. If you turn this off, the image is not zoomed at all,
and whatever black bars intrude into the image are output along
with the image, on the assumption that you’ll have dedicated
compositing artists deal with eliminating these black edges in a
more sophisticated manner.
