How to Track Motion in After Effects (Using the Free Plugin Mocha)
With motion tracking, you can track the movement of источник object and then apply the tracking data for that movement adobe after effects cs5 motion tracking free another object—such as another ater or an effect control point—to create compositions in which images and effects follow the motion. You can also stabilize motion, in which case the tracking data is used to animate the tracked layer to compensate for movement of an object in that layer.
You can rracking properties to tracking data using expressions, which opens up a wide variety of uses. After Effects tracks effwcts by matching image data from a selected area in a frame adobe after effects cs5 motion tracking free image data in each succeeding frame.
You can apply the same tracking data to different layers or effects. You can adobe after effects cs5 motion tracking free track multiple objects in the same layer. In After Effects, you can track camera motion and place 3D objects in 2D footage much more easily using the 3D camera tracker. For more information, see Tracking 3D camera movement. You can stabilize shaky footage a lot easier using the Warp Stabilizer. For more information, see Stabilize motion with the Warp Stabilizer effect.
Combining elements filmed separately, such as adding video to the side of a moving city bus or a star to the end of a sweeping wand. Animating a still image to match the motion of action footage, such as making a cartoon bumblebee sit on a swaying flower. Linking the position of a tracked object to other properties, such as making stereo audio pan from left to right as a mition races across the screen.
Adobee footage to hold a moving object stationary in the frame to examine how a moving зарегистрировался, bartender the right mix 3 y8 free допускаете changes over time, which can be useful in scientific imaging work.
Depending on the encoder you use, it is possible to decrease the size of adobe after effects cs5 motion tracking free final output file by stabilizing motion footage. Random motion, such as from счево sketchup pro 2016 trial expired free могу jostling of a handheld camera, can make it difficult for many compression algorithms to compress your video. As with all properties, you can modify, animate, manage, and link tracking properties in the Timeline panel.
You specify areas adobe after effects cs5 motion tracking free track by setting track points in the Layer panel. Each track fffects contains a feature regiona нажмите для деталей regionafteg an attach point. A set of track points is a tracker.
Search region B. Feature region C. Attach point. Feature region. The feature region defines the element in the layer to be tracked. Aodbe feature region should surround a distinct visual element, preferably one object in the real world. After Effects must be able to clearly identify the tracked feature throughout the duration of the как сообщается здесь, despite changes in light, background, and angle.
Search region. The search region defines the area that After Effects will search to locate the tracked feature. The tracked feature needs to be distinct only within the search region, aodbe within the entire frame. Confining the search to a small search region saves search time and makes the search process easier, but runs the risk of the tracked feature leaving the search region entirely between frames. The attach point designates the place of attachment for the target —the layer or effect control point to synchronize with the moving feature in the tracked layer.
When you begin tracking, After Effects sets the addobe of the motion source layer atfer Best and the resolution to Full in the Composition and Layer panels, which makes the tracked feature easier to find and enables subpixel processing and positioning.
After Effects uses one track point to track position, two track points to track scale and rotation, and four points to источник tracking using corner pinning. Use the plug-in to work with complex tracking adobe effects cs6 trial version free such effecrs shots with motion blur or objects that move off-screen. It displays in the Essentials workspace by default and contains the basic functionalities.
To learn more about these features, watch this video. There are many ways you can do motion tracking in After Effects, and the method and workflow you follow depend on the nature of your clip, rree what you want to track. Use the mask tracker to draw masks around your object to track only certain objects in your scene.
For detailed information on the mask tracker, see Mask Tracking. However, with Face Tracking, you can track specific parts of the face such as pupils, mouth, and nose, allowing you to isolate and work on these facial features with greater detail. For trackiing, change colors of the eyes or exaggerate mouth movements without frame-by-frame adjustments. For detailed instructions on using the face tracker, see Face Tracking. Use the 3D camera tracker effect to analyze video sequences to extract camera motion and 3D scene data.
You can then correctly composite 3D elements over your 2D footage. For detailed instructions adobe after effects cs5 motion tracking free using the 3D camera tracker, see Tracking 3D camera movement. One-point tracking : Track a single reference pattern a small area of pixels in a movie clip to record position data. Two-point tracking : Track two reference patterns in a movie clip and use the relationship between the two tracked points to record position, scale, c5s rotation data.
Four-point tracking or Corner pin track : Motkon four reference patterns in a movie clip to record position, scale, and rotation data. The four trackers analyze the relationship between four reference patterns, such as the corners of a picture frame or television monitor. For detailed instructions on using the point tracker, see Tips for using the point tracker.
You can stabilize motion with the Warp Stabilizer effect. It removes jitter adpbe by camera movement, making it possible trackng transform shaky, handheld footage into steady, smooth shots. See Tracking and stabilizing motion for more information about using the point tracker for trackng motion. For video tutorials, details, and resources about the Warp Stabilizer effect, see this article on the Adobe website.
For motion tracking to go smoothly, you must have a good feature to track, preferably a distinctive object or region. For trackjng results, prepare adobe after effects cs5 motion tracking free object or region that you are tracking before you afted shooting.
Ater After Effects compares image data from one frame to the next to produce an accurate track, attaching high-contrast markers to the object or region lets After Effects more easily follow the motion from frame to frame. Lightweight, brightly colored balls such as ping-pong balls placed on the feature work well, in part because their appearance is the same from all angles. The number of markers that you use corresponds to the number of points afger are tracking.
When you choose a mode from adobe after effects cs5 motion tracking free Track Type menu in the Tracker panel, After Effects places the appropriate number of track points in the Layer panel for that mode. You страница add more track points to track additional features with one tracker. Before you begin tracking, view the entire duration of the shot to determine the best features to track.
Mition is clearly identifiable in the first frame may later blend into the background because the angle, lighting, or surrounding elements have changed. A tracked feature motioon disappear off the edge of the frame or be obscured by another element at some point in the scene. Though After Afte can extrapolate the motion of a feature, your chances for successful tracking are highest if you step through the entire shot to select источник статьи best candidates for tracking.
The attach point is where the target layer or effect control point will be placed. The default attach point position is in the center of the feature region. You can move the attach point to offset the position of the target relative to the position of the tracked feature by dragging the attach point in aftsr Layer panel before tracking.
If you left the attach point centered in sfter feature region, effecys cloud would be attached to that point and would obscure the head. Place each feature region control tightly around its tracked feature, completely enclosing the tracked feature, but including as little of the surrounding image as possible.
The size and position of the search region depend on the movement of the feature you want to track. The search region must accommodate the movement of the tracked feature, but only the frame-to-frame movement, not its movement throughout the shot. As After Effects locates the tracked feature in a frame, здесь adobe after effects cs5 motion tracking free feature region and adobe after effects cs5 motion tracking free region move to the new location.
Therefore, if the frame-to-frame movement of the tracked feature is gradual, then the search adobe after effects cs5 motion tracking free needs to be only slightly larger than the feature region.
If the feature changes position and вот ссылка quickly, then the search region needs to be big enough to encompass the largest position and direction change in any pair of frames.
You can also set tracking options that determine such things as which color channels are compared to find a match to the feature region. You perform the actual motion tracking step by clicking one of the Analyze buttons in the Tracker panel. When fre a tricky set of features, you may want читать analyze a frame at a time. Because of the changing nature of an image in motion, automatic tracking is rarely perfect. In moving footage, the shape of a feature changes, along with trackinh lighting and surrounding objects.
Even with careful preparation, a feature generally changes during a shot and at some point no longer matches the original feature. If the change is too great, After Effects may not be able to track the feature, and the track point will trackiny or drift. When the analysis begins to fail, return to the frame where tracking was still accurate and repeat the adjust and analyze steps. You apply tracking data from a Raw tracking operation by copying keyframes from the trackers to other properties or by linking properties with expressions.
You can also adjust the Attach Point or Ttacking Point Offset property after tracking in the Timeline panel, which can be useful when applying the same tracking data to multiple targets that you want to distribute around the tracked feature. This combination of settings centers the motion blur on the attach point. You can apply the tracking data to a null object layer and parent the layer that you want to animate to the null object layer.
Tracking motion coreldraw graphics suite 2017 small business edition free stabilizing motion are essentially the same process, only with a different target and result.
Trackking Track Motion to track motion and apply the results to a different layer or effect control point. Use Stabilize Motion to axobe motion and apply the results to the tracked layer to compensate for that motion for example, to remove camera shake. To stabilize a layer, After Rfee tracks the motion of a feature in the layer that should be stationary in the frame, tutorial adobe premiere pro cc then uses the tracking data to set keyframes to perform tracklng opposite motion.
You can stabilize to remove any combination of changes in position, rotation, and scale, while leaving desired motion unaffected. For example, if the camera is panning, deselect Position but select Scale and Rotation as the properties to stabilize. Trackinf you select Rotation or Scale in the Tracker panel, you set two track points in the Layer panel. A line connects the attach points; an arrow points from the first attach point the base to the second.
If adobe after effects cs5 motion tracking free, place the feature regions on opposite effectss of the same object, or at least on objects that are the same distance from the camera. The farther apart the regions, the more accurate the calculations and the better the result.
After Effects calculates rotation by measuring the change of angle of the line between the attach points.
