Let’s begin!

Let’s start!

【No.08-04】【After Effects】[Beginner] HOW TO USE TRACK MOTION

After Effects has a function called Tracking. Tracking allows you to analyze the movement of objects and combine other materials matching the movement.

There are two methods of analysis: Track Motion that analyzes two-dimensional movements, and Track Camera that analyze three-dimensional movements.

Here we will use Track Motion to analyze 2D movements!

Prepare materials

Place the video material on the timeline. We will analyze the movement of red shoes!

The higher the contrast of an object, the more accurate the analysis is.

Next, we will create a figure that follow the movement of the red shoes!

Place the hand-pointing layer that follow the movement like this.

We will adjust the position later, so you can temporarily place it in the approxiamate range !

Timeline panel will look like this. The hand-pointing layer is placed above the video layer.

Specify Track Point

This is the Tracker panel.

Select the video layer you want to analyze and click Track Motion.

Then in the Layer panel opens, Track Point will be displayed, so drag it to the object you want to follow.

[Track Point] has double squares.

The inner square is the range of follow-up objects and the outer square is the range of search. The wider the range of the outer square is, the longer time the analysis takes.

Analysis

Now we will proceed to analyze it!

In the Timeline panel, drag the playhead to the frame position where you want to start the analysis.

In the Tracker panel, press this button to start the analysis.

Analysis completed! In the Layer panel, you can see that the Trackpoint follows the movement of the object.

Edit Target

A figure that follows a movement is called a target. We will go to specify the target!

Click Edit Target on the Tracker panel.

In the Layer, choose hand-pointing layer and press OK button.

When you click Apply, the Target will follow the movement of the object.

In Apply Dimensions, select X and Y and click OK. Then the target can follow the horizontal or vertical movement.

In the Timeline panel, open the Transform properties of the figure you specified as the Target.

As you can see, there are keyframes set in the Position property like this.

Finally, adjust the position of the hand-pointing layer. Please remember to select all key keyframes before adjusting the position.

Completed

Play the preview in Composition Panel to see the result.

This is the end of the lecture on how to use Track Motion!
