Workflows of Motion Track

• There are many ways you can do motion track in
  After Effects, and the workflow and method you
  follow the nature of your clip, and what you want
  to track.

Mask Tracker

• Use of mask tracker to draw masks around the
  object to track the certain objects in the scene.
• However, with Face Tracking, you can track
  particular parts of the face such as pupils,
  mouth, and nose, allowing you to isolate and work
  on those facial features with greater detail.

Face tracker

• Simple mask tracking lets you quickly apply
  effects only to a face, such as selective color
  correction or blurring a persons face, and more.

7

• Example, change colors of the eyes or exaggerate
  mouth movements without frame-by-frame
  adjustments.

3D Camera Tracker

• Use the 3D camera tracker effect to analyze the
  video sequences to extract the camera motion and
  3D scene data.
• You can then correctly composite the 3D elements
  over the 2D footage.

Point Tracker

• You can track one or multiple reference features
  in a clip

10

• 1. One-Point Tracking
• Track a single reference pattern in a movie clip
  to record the position data.

11

• 2. Two-Point Tracking
• Track two reference patterns in a movie clip and
  use the relationship between the two tracked
  points to record position, scale, and rotation
  data.

12

• 3. Four-Point Tracking
• Track four reference patterns in a movie clip to
  record position, scale, and rotation data.
• The four trackers analyze the relationship
  between the four reference patterns, such as
  corners of a picture frame or TV monitor.

13

• This data is applied to each corner of image or
  clip to pin the clip so that it appears locked
  in the picture frame or TV monitor.

14

• 4. Multiple-Point Tracking
• Track as many reference patterns in a clip as you
  like.
• You can manually add trackers to the Analyze
  Motion and Stabilize behaviours.

15

• When you apply a Track Points behaviour from the
  Shape behaviours subcategory to shape or mask, a
  tracker is automatically assigned to each shape
  control point.
