FCPX Auto-Tracker Tutorial
Welcome to a Final Cut Pro X Auto-Tracker tutorial from Pixel Film Studios.
In this tutorial, we’ll be going over
1) How use the FCPX Auto-Tracker
2) Making Manual Adjustments & Retracking
Lets get started.
In this example we’ll be tracking text to the movement of a young hockey player.
First, we’ll find the FCPX Auto-Tracker in the effects section and apply it directly onto the footage.
Next, we’ll look to the PRE-TRACK OPTIONS to determine if we want to track scale and rotation. Additionally, users can adjust the tracker’s tolerance for tracking inexact frames. For this example, we’ll toggle on both scale and rotation and make the tracker relatively strict to ensure an accurate track.
We’ll move the playhead to a frame along the video clip that we want to begin tracking. In this example, we’ll move the playhead to the first frame of the footage. Next, use the green on-screen control to select an area to track. For this example, we’ll move the selection box on top of his face and drag the corner to match the size of his face. Now that the on-screen control is in place, I’ll click “TRACK FORWARD” to track to the right of playhead.
Alternatively, I can move the playhead to the last frame of the video clip and use “TRACK BACKWARDS” to track to the left of the playhead.
As we play back the clip, we see that the text now tracks to the position, scale, and rotation of the player.
Sometimes the tracker will lose its position if the selected area changes over time. This could be due to changes in lighting, angling, or if the area becomes blocked.
Here, we have a clip of a football player that we’ve tracked. At around 4 seconds, the player begins to spin and another player moves in front of his helmet and the tracker loses its position. To correct for this, we can resume tracking, move track points, add track points, and delete track points.
We’ll move the playhead forward in the timeline to a frame when of his helmet is fully cleared of the other player. Then move the selection box to match the position of the helmet, and click “TRACK FORWARD” to resume tracking.
As we play the clip back, you’ll notice that track is imperfect in between the two paths. To delete unwanted points, hold down the “Option” key and click to delete any unwanted points individually. If you want to delete a group of points at once, change the DELETE MODE to SET, and select two points while holding down the “Option” key. Auto-Tracker will delete all of the points in between the selected points. Next we’ll scrub to an empty frame in the path, hold down the option key, and click to add points.
Lastly, we’ll use toggle on the OFFSET GUIDE and use the blue on-screen control to offset the position the entire path to the right of the players face and complete the scene.
