FCPX Auto-Tracker 1.1 Tutorial
Welcome to a FCPX Auto Tracker tutorial from Pixel Film Studios
In this tutorial we’ll be going over three things.
1. User Interface Controls
2. Tracking Controls
3. Text & Media Controls
Let’s get started.
We’ll begin by dragging the FCPX Auto Tracker effect preset directly onto our footage.
Select a corresponding resolution that matches your media.
For this example we will select the hd title text effect preset located within the Titles Browser.
Click and drag this preset over your media within the timeline and match up it’s length to the length of your media.
Compound the media along with the title overlay, and then double click the compound to begin.
Using the guid user interface controls.
The Rectangle Tool
Each effect preset will default to the rectangle tool.
While your mouse is hovering over this shape it will highlighted.
To adjust overall scale left click and hold on any white box on the outer edge.
To adjust the overall rotation left click and hold on the outer blue circle.
Left click and drag this box over the object you wish to track.
You then have the option of clicking each inner control point and relocating them to outline your subject matter.
Keep in mind that the orientation of this track will be the center blue circle and it’s rotation will stem out from that control point.
To create a custom rectangle click on third icon from top to bottom and then left click and drag within the viewer window.
The Custom Polygon Tool
Left click on the second icon from the top down to create a custom polygon.
Left click within the viewer window and create an outline around the object you wish to track.
To delete a point hold down the option key and left click on the point you wish to delete.
Establishing a fluid and complete track with Tracking Controls
Located under the pre-track options category you will find the search size slider.
For scenes with large amounts of motion it is recommend to increase this slider’s value.
For your average track we recommend this slider to be set at a value anywhere from ten to thirty.
To record the tracking’s scale throughout track click on the track scale check box.
To record the tracking’s rotation throughout track click on the track rotation check box..
We’ll begin by scrubbing to the beginning or end of our clip to the point where our subject matter is most defined.
While tracking forward or in reverse at any point in time the subject matter becomes blurry or out of site, we will need to click the stop track button and manually keyframe.
Scrub through your timeline and with the track point highlighted left click and drag to create a keyframe.
Deleting Track Points
Located under post-track options, under keyframe deletion type, select individual to delete a individual keyframe.
Scrub through your timeline until the point you wish to delete is highlighted in yellow.
Hold down the option key and then left click within the highlighted box to delete this track point.
To delete a set of track points select set under the deletion type.
Scrub to the first track point you wish to delete.
Click on the key icon within the user interface and then scrub to the last track point you wish to delete, and click on the key icon once more.
While holding down the option key, click within the highlighted box.
These set of track points will now be deleted.
Continue these steps until you have created a successful track.
Once your subject matter becomes visible and within focus you can then continue to track from that point in time
Once our tracking data is now complete, we can make further adjustments to our tracked media.
Adjust the overall scale with the scale slider
Offset your media’s rotation with rotation offset.
Adjust the overall opacity with the opacity slider
Offset your media’s x, y, and z, anchor point.
To offset your track points as a whole hover your mouse over the white box within the view finder left click and hold the shift key while draging to a new location.
Release your mouse and then release the shift key.
Your track points have now been relocated.
