Introduction
This is the result we will create: a label name and a marker circle that stick and move with the Vantua car on top of the bridge, the result of real motion tracking. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Module 11 covers motion tracking, which is the technique of tracking the movement of an object in a video and then using that data to animate another layer. We start with the most basic: tracking a single point. Create a composition from the fan footage on the bridge and go to frame 3, when the fan is approaching.
Step 1: Preparing the clip
Notice the right front light of the fan, small, bright, and high contrast with the white body around it. A point like this is the easiest to track.
Step 2: Null, label, and marker
Create an object named 'track point'. This object will later receive the tracking data. Then create the text 'VW Kombi' above the fan and a yellow circle without fill around the front light. Select the footage layer, open the tracker panel, then click 'Track Motion'.
Step 3: Track Motion
The footage opens in the layer panel and a 'track point 1' appears. The inner box is the search area, the outer box is the search area. Drag the track point to the front light, then click 'Analyze Forward'. After Effects searches for the same pattern frame by frame. The track point's trail is visible following the fan until frame 5.5.
Step 4: Edit Target and Apply
Click 'Edit Target', select the 'track point' layer, okay, then click 'Apply' and select 'X and Y'. The object now has position keyframes on every frame, the result of real tracking.
Step 5: Parenting to null
In the 'Print and Link' column, drag the 'PIKWip label VW Kombi' and the marker circle to the 'track point'. Both now move together with the object, while their relative positions can still be freely adjusted.
Step 6: Preview
Adjust the work range from frame 3 to 5.5, then play the preview. The label and marker are now attached to the moving fan. Using the object as an intermediary is a professional habit, because the tracking data can be used for many layers.
Done!
Done We have already selected a high-contrast point, using motion tracking with the feature box and search tool, analyzed forward, applied the data through edit target and apply, then attached the label with the pinning. In the next episode, we will track two points for rotation and scaling. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films.
