Stabilizing an Image
| Effect Mode button |
| Region Stabilize AVX effect icon |
To stabilize a segment:
| 1. | |
Open the Effect Palette by doing one of the following:
|
| |
In the Project window, click the Effects tab.
|
|
| |
Select Tools > Effect Palette.
|
| 2. | |
Click the Image category.
|
| 3. | |
Drag the Region Stabilize Effect icon to the segment you want to
stabilize.
|
| 4. | |
Select Tools > Effect Editor.
|
A wire frame appears in the Effect Preview monitor to indicate the
region of interest. This is the area you want to use in stabilizing the
image.
| 5. | |
Reposition and resize the wire frame by doing one of the following:
|
|
| |
Use the sliders in the Region of Interest parameter category.
|
|
| |
Click the wire frame, and drag it in the Effect Preview monitor.
|
Select a region that contains one or more features that do not change
much from frame to frame, for example, objects such as buildings or
rocks. Another approach is to shoot the scene with stabilization in
mind: include an object, such as a reflective sticker, that you intend to
use as your region of interest.
| 6. | |
Click the Model Fast Menu button, and select the type of stabilization:
|
| – |
|
Translational keeps the region of interest steady along both the
horizontal and the vertical axis.
|
| – |
|
Horizontal constrains horizontal motion in the region of interest.
Features in the region of interest can move vertically but not
horizontally.
|
| – |
|
Vertical constrains vertical motion in the region of interest.
Features in the region of interest can move horizontally but not
vertically.
|
| 7. | |
(Option) To turn on Auto Zoom, open the Options parameter category
and click the Auto Zoom button.
|
Stabilization exposes black around the edges of the repositioned
frames. Auto Zoom compensates by resizing and, if necessary,
repositioning the clip to remove the exposed edges.
| 8. | |
(Option) If your footage was captured as or converted to progressive
footage (is not interlaced), open the Options parameter category and
click the Progressive Source button.
|
If your sources are progressive, enabling this button produces
smoother results.
| 9. | |
Render and review the effect.
|
| 10. | |
(Option) Add keyframes to further refine the motion of the stabilized
clip.
|
| 11. | |
Continue to review and refine the effect until you achieve the results
you want.
|
| 12. | |
(Option) Resize and, if necessary, reposition the clip to eliminate black
edges.
