How To Track 3d Objects In After Effects
Track 3D Objects In After Effects
What is 3D Tracking?
3D tracking is a technique used in After Effects to analyze a video clip, identify a specific object within it and then track that object’s movement from frame to frame. This allows for the creation of 3D objects or effects that can be placed in the scene and follow the movement of the object being tracked. As you can imagine, this can open all sorts of possibilities when it comes to creating dynamic visuals.
What is After Effects?
After Effects is a motion graphics, animation and compositing program developed by Adobe Systems. It is used by professionals in the film, television, and video game industries to create stunning visual effects and motion graphics. With After Effects, you can create 3D scenes and add 3D effects to your videos, as well as create complex motion graphics and animations. It is also used in the creation of special effects for movies and television.
Preparing the Scene
Before you can begin tracking a 3D object in After Effects, you will need to create a scene that contains an object you want to track. This could be anything from a simple object, like a ball, to a complex object, like a car. You can create the scene in After Effects or import it from another program. Once you have your scene set up, you will need to define the 3D tracking points for the object.
Defining the Tracking Points
In order to track a 3D object in After Effects, you will need to define the 3D tracking points for the object. These points will be used to define the motion of the object and to follow the object’s movement from frame to frame. To define the 3D tracking points, you will need to place tracking markers on the object that you want to track. This can be done manually, or you can use a tracking tool such as ReelSteady to automate the process.
Tracking the Object
Once you have defined the 3D tracking points, you can begin tracking the object. To do this, you will need to select the track point you want to track and then click on the “Track” button. This will begin the tracking process. Once the tracking is complete, you will be able to see the 3D object’s motion from frame to frame and you will be able to adjust the tracking points if needed.
Creating the 3D Object
Once the 3D tracking is complete, you can create the 3D object or effect that you want to place in the scene. You can do this by using the 3D tracking data that was gathered from the tracking process. This data will allow you to accurately place the 3D object in the scene and have it follow the motion of the tracked object. You can also use the 3D tracking data to add motion blur and other effects to the 3D object, making it look more realistic.
Conclusion
Tracking 3D objects in After Effects is a great way to create dynamic visuals and add realistic motion to your videos. By defining 3D tracking points and tracking the object’s motion, you can easily create 3D objects or effects that will follow the object’s movements. With After Effects, you can bring your videos to life and create stunning visuals for your projects.
