11:00 Motion Tracking with After Effects
Motion Tracking is the concept of following objects in footage so that you can add new objects to that scene and create a interesting and believable composition.
The process consists of automatically locating a point or a series of points from a frame to frame to frame sequence
Motion tracking makes visual sequences waaaay more interesting!
Motion Tracking methods may include:
- Single Point Tracking – which tracks X and Y coordinates
- Two Point Tracking for when you want to include rotation and scale
- Mask Tracking (also called Rotoscoping) to isolate masks in a shot
- Camera Tracking – follows the action and coordinates of the camera in three dimensional space
- Planar Tracking – following a surface or sign that you want to replace.
Tracker Features
The tracker is made up of two boxes and an attach point.
The outside box is called the search region and defines what type of data to search for.
The inside box is called the feature region and it looks for the features that are similar to the attach point
You can expand and contract both of those boxes to try for the best tracking
Auto tracking is handled by After Effects. To get a good track, keep in mind:
- Good contrast is important
- Work in full resolution
- Start with high quality footage
Assignment – Choose 1
Option #1 The “Conversation” (2D/Point Tracking) -Using the following video
Concept: You track two people, create a series of animated call-outs that follow each individual perfectly
Application: Demonstrates proficiency in 2D (Point) Tracking for position, scale, and rotation.
Target: Each person has it’s own tracking data located above their head
Deliverable: A short video where the two individuals have a conversation that is visible with animated callouts
Option #2 The “Virtual T-Shirt” or Graphic Overlay (2D/Point Tracking) – Using the following video or this video
Concept: You track a moving surface on a person and affix a graphic, like a logo to it.
Application: Demonstrates proficiency in 2D (Point) Tracking for position, scale, and rotation.
Target: Front of a T-Shirt
Deliverable: A short video where the graphic stays perfectly “stuck” to the moving target throughout the shot.
Use what you’ve learned in After Effects. You might consider using your animated logo for Option#2 or something else custom.
