Offset the search region center from the feature region center in the direction in which the tracked feature is traveling. To restrict the movement of the track point to the x horizontal or y vertical axis during tracking, resize the height or width of the search region to match the height or width of the feature region. For example, you can apply the track to the position of a light bulb and to the effect control point of the Lens Flare effect.
As an image moves in a shot, the lighting, surrounding objects, and angle of the object can all change, making the once-distinct feature no longer identifiable at the subpixel level. Also, if the search region is too small, the tracked feature may leave its bounds from one frame to the next. Learning to choose a trackable feature takes time. Even with careful planning and practice, the feature region can drift away from the desired feature.
Re-adjusting the feature and search regions, changing the tracking settings, and trying again is a standard part of automatic tracking. You may need to track the shot in sections, redefining the feature region in places where the feature changes and the region drifts. You may even need to choose a different feature to track, one with movement that closely matches that of the feature to track, and use the attach point offset to place the target.
You can fine-tune the keyframes of the motion path in the Layer panel as you would any other motion path. Modifying the motion path is most useful when you want to manually change the motion tracking data before applying it to a target.
In some cases, it may be easier to manually modify the motion path created by the motion tracker than to get a perfect track. Moving the feature and search regions B. Keyframe marker. After the effect is added to the layer, analysis of the footage begins immediately in the background.
As analysis begins, the first of two banners displays in the Composition panel indicating that analysis is occurring. When analysis is complete, the second banner displays a message that stabilization is occurring. You are free to work with the footage or elsewhere in the project while these steps are occurring. There is no need to press this button when you first apply Warp Stabilizer; it's pressed for you automatically. The Analyze button remains dimmed until some change takes place.
Click the button to reanalyze the footage. Analysis does not take into account any masks or effects that are applied directly to the same layer. Pre-compose and place them in the upstream composition if you want them to be analyzed. Cancels an analysis in progress. During analysis, status information appears next to the Cancel button. Smooth motion default : Retains the original camera movement but makes it smoother.
When selected, Smoothness is enabled to control how smooth the camera movement becomes. No Motion : Attempts to remove all camera motion from the shot. This setting is used for footage where at least a portion of the main subject remains within the frame for the entire range being analyzed. Values above require more cropping of the image.
Enabled when the Result is set to Smooth Motion. Specifies the most complex operation the Warp Stabilizer performs on the footage to stabilize it:.
Position Tracking is based on position data only and is the most basic way footage can be stabilized. Position, Scale And Rotation Stabilization is based upon position, scale, and rotation data. If there are not enough areas to track, Warp Stabilizer chooses the previous type Position. Perspective : Uses a type of stabilization in which the entire frame is effectively corner-pinned. If there are not enough areas to track, Warp Stabilizer chooses the previous type Position, Scale, Rotation.
Subspace Warp default : Attempts to warp various parts of the frame differently to stabilize the entire frame. If there are not enough areas to track, Warp Stabilizer choose the previous type Perspective. The method in use on any given frame can change across the course of the clip based on the tracking accuracy. Note : In some cases, Subspace Warp can introduce unwanted warping, and Perspective can introduce unwanted keystoning.
You can prevent anomalies by choosing a simpler method. Preserve Scale. After Effects When enabled, prevents the Warp Stabilizer from trying to adjust forward and backward camera movements with scale adjustments. Borders settings adjust how borders the moving edges are treated for footage that is stabilized.
Controls how the edges appear in a stabilizing result. Framing can be set to one of the following:. It is possible for artifacts to appear when there is movement at the edge of the frame not related to camera movement. Displays the current auto-scale amount, and allows you to set limits on the amount of auto-scaling. Enable Auto-scale by setting framing to Stabilize, Crop, Auto-scale. Additional Scale. Scales up the clip with the same result as scaling using the Scale property under Transform, but avoids an extra resampling of the image.
Detailed Analysis. When set to on, makes the next Analysis phase do extra work to find elements to track. The resulting data stored in the project as part of the effect is much larger and slower with this option enabled.
Rolling Shutter Ripple. The stabilizer automatically removes the rippling associated with stabilized rolling shutter footage.
Automatic Reduction is the default. Use Enhanced Reduction if the footage contains larger ripples. To use either method, set the Method to Subspace Warp or Perspective. When cropping, controls the trade-off between smoothness and scaling of the cropping rectangle as it moves over the stabilized image. Lower values are smooth, however, more of the image is viewed.
Synthesis Input Range seconds. Used by Stabilize, Synthesize Edges framing, controls how far backward and forward in time the synthesis process goes to fill in any missing pixels. Synthesis Edge Feather. Selects the amount of feather for the synthesized pieces. It is enabled only when using the Stabilize, Synthesize Edges framing.
Use the feather control to smooth over edges where the synthesized pixels join up with the original frame. Synthesis Edge Cropping. Trims off the edges of each frame before it is used to combine with other frames when using the Stabilize, Synthesize Edges framing option.
Use the cropping controls to crop off bad edges that are common in analog video capture, or low quality optics. By default, all edges are set to zero pixels. Determines the aim for the effect: for stabilizing, for temporary stabilization to perform visual effects work, or to composite a layer into a shaky scene. Choose an objective:. Target Layer. Choose a layer to which the stabilized motion is applied using the Apply Motion to Target or Apply Motion to Target over Original options.
Show Track Points. Track Point Size. Auto-delete Points Across Time. When you delete track points in a composition panel, corresponding track points on the same object, are deleted at other times on the layer. You do not need to manually delete the track points frame-by-frame. Hide Warning Banner. While the Warp Stabilizer effect is analyzing your footage, you can adjust settings or work on a different part of your project. If you want to get a feel for how much work the stabilizer is actually doing, set the Framing to Stabilize Only.

Uses for motion tracking and stabilization. Motion tracking has many uses. Here are some examples:. Animating effects to follow a moving element, such as making a moving ball glow. Stabilizing footage to remove the jostling camera shake of a handheld camera. Motion tracking user interface and terminology overview.
You set up, initiate, and apply motion tracking with the Tracker panel. Online resources for motion tracking and stabilization. Chris and Trish Meyer provide a video tutorial on the ProVideo Coalition website that demonstrates and explains the basics of motion tracking.
Angie Taylor provides a tutorial on the Digital Arts website that shows how to use tracking data and the Clone Stamp tool to apply copies of an object in a scene while matching a camera move.

This post on the AE Enhancers forum describes and links to a script from Paul Tuersley that takes a stabilized layer, precomposes it, and then adds expressions that counter the stabilization. Planar Tracking with Mocha AE. Click the Mocha logo in the Effect Controls panel to launch the user interface. T hen select either Corner Pin or Transform. Apply Export to the selected layer. Motion tracking workflows.
Mask tracker. Face tracker. Point tracker. You can track one or multiple reference features in a clip: One-point tracking : Track a single reference pattern a small area of pixels in a movie clip to record position data. Multiple-point tracking : Track as many reference patterns in a clip as you like. You can manually add trackers within the Analyze Motion and Stabilize behaviors. When you apply a Track Points behavior from the Shape behaviors subcategory to a shape or mask, a tracker is automatically assigned to each shape control point.
Warp stabilizer VFX. Tips for using the point tracker. Set up the shot. Add the appropriate number of track points. Select features to track, and place feature regions. A good tracked feature has these characteristics:. Visibility for the entire shot A contrasting color from the surrounding area in the search region A distinct shape within the search region A consistent shape and color throughout the shot.
Set the attach point offset. Adjust the feature region, search region, and tracking options. Repeat as necessary. Apply tracking data. Track or stabilize motion with the point tracker. Select the layer to track in the Timeline panel.
Do one of the following:. The target layer is the tracked source layer. Move the current-time indicator to the frame from which to begin tracking. Using the Selection tool, adjust the feature region, search region, and attach point for each track point.
When you are satisfied with the position of the feature region and attach point throughout the track, click the Apply button to apply the motion to the specified target.
After Effects creates keyframes for the target layer. X And Y default allows motion along both axes. X Only restricts the motion target to horizontal movement. Y Only restricts the motion target to vertical movement. Motion tracking controls. The layer that contains the motion to track. Track Type. Begins the frame-to-frame analysis of the track point in the source footage: Analyze 1 Frame Backward : Analyze the current frame by moving back to the previous frame.
Sends the tracking data in the form of keyframes to the target layer or effect control point. Motion tracking options. Track Name. Select Continue Tracking to ignore the Confidence value. This behavior is the default behavior. Select Stop Tracking to stop the motion tracking. Select Extrapolate Motion to estimate the position of the feature region.
Select Adapt Feature to use the original tracked feature until the confidence level falls below the specified threshold. At that point, After Effects adapts the tracked feature to be the contents of the feature region in the frame preceding the one that has low confidence and continues tracking.
Motion tracking properties in the Timeline panel. Position of the center of the feature region. Width and height of the feature region. Position of the center of the search region relative to the center of the feature region. Search Size. Width and height of the search region. Position assigned to the target layer or effect control point.
Position of the attach point relative to the center of the feature region. Adjust the track point. To turn on or off feature region magnification, choose Magnify Feature When Dragging from the Tracker panel menu. To move the feature region, search region, and attach point together, drag inside the track point area avoiding the region edges and the attach point , or press the Up, Down, Left, or Right Arrow key.
Hold Shift while pressing an arrow key to move by an increment 10 times as large. To move only the feature and search regions together, drag the edge of the feature region, or Alt-drag Windows or Option-drag Mac OS with the Selection tool inside the feature or search region. To move only the search region, drag the edge of the search region.
To move only the attach point, drag the attach point. To resize the feature or search region, drag a corner handle. To make all of the sides of the region match the length of the longest side, and to resize the region relative to the original center point of the region, Shift-drag a corner handle. Apply tracking data to a new target. In the Tracker panel, choose the tracked layer from the Motion Source menu. Choose the track that contains the tracking data you want from the Current Track menu.
Click Edit Target, and choose the target. In the Tracker panel, click the Apply button. Correct a motion track. Correct drifting by adjusting the feature and search regions. Move the current-time indicator to the last well-tracked frame. Alt-drag Windows or Option-drag Mac OS the feature and search regions only not the attach point to the correct location. If you are correcting the track for one frame, go to step 4. If you are correcting the track for several contiguous frames, adjust the feature region and search region if necessary, and click Analyze.
Watch the tracking to make sure that it is accurate. If the tracking is not accurate, then click the button again to stop tracking, adjust the feature region, and begin again.
When you are satisfied with the track, click Apply to apply the keyframes to the target layer or effect control point. Correct drifting by modifying tracking settings.
In the Tracker panel, click Options. Change settings in the Motion Tracker dialog box as appropriate. See Motion tracking options. If the tracking is not accurate, then click the button again to stop tracking, adjust the settings, and begin again.
An upgrade to the Warp Stabilizer, VFX adds the ability to choose which objects within a scene get stabilized. Steve Forde. Stabilize with the Warp Stabilizer effect. To stabilize motion using the Warp Stabilizer effect, do the following:. Select the layer you want to stabilize. Stabilization settings allow for adjusting the stabilization process.
Controls the intended result for the footage Smooth or No Motion. Specifies the most complex operation the Warp Stabilizer performs on the footage to stabilize it: Position Tracking is based on position data only and is the most basic way footage can be stabilized. Borders Borders settings adjust how borders the moving edges are treated for footage that is stabilized.
Framing can be set to one of the following: Stabilize Only : Displays the entire frame, including the moving edges. Stabilize Only shows how much work is being done to stabilize the image.
Using Stabilize Only allows you to crop the footage using other methods. Stabilize, Crop : Crops the moving edges without scaling. Stabilize, Crop, Auto-scale default : Crops the moving edges and scales up the image to refill the frame.
The automatic scaling is controlled by various properties in the Auto-scale section. Stabilize, Synthesize Edges : Fills in the blank space created by the moving edges with content from frames earlier and later in time controlled by Synthesizes Input Range in the Advanced section.
Maximum Scale: Limits the maximum amount a clip is scaled up for stabilization. Thus, auto-scale does not try to fill it. Choose an objective: Stabilize Default option for normal stabilization Reversible Stabilization and Reverse Stabilization Use these options to apply an effect to a region. Use two instances of the Warp Stabilizer VFX effect, one with Reversible Stabilization to steady a shaky object, and a duplicate instance with Reverse Stabilization to insert the shake back in, so that any effects you apply after Reversible Stabilization appear within the original scene.
Apply Motion to Target and Apply Motion to Target over Original Use these options to composite a layer into a shaky scene to apply the stabilized motion onto a different layer.
Determines if track points are displayed.
