![]() Then, click the left-pointing arrows to track from the initial position of the playhead to the beginning of the clip.Īfter a few seconds – the speed depends upon the speed of your computer along with the duration of the clip – the analysis is complete. If you need to start the track from the middle of a clip, click the right-pointing arrows next to Analyze to track from the position of the playhead to the end of the clip. If the playhead is at the start of the background clip, click the Analyze button. Remember, these controls only appear when the foreground clip is selected.Ĭlick the Tracker button in the middle to turn on the Tracker. NOTE: If these controls don’t appear, click the Transform icon in the lower left corner of the Viewer to turn them on. When the foreground is properly positioned, look at the top of the Viewer. You can put the foreground element anywhere in the frame. In my case, I’m putting the fisherman is in the bubble. Size and position this clip until it is located where you want. When the tracking rectangle is properly sized, select the top (foreground) clip. The four red dots along the edges of the rectangle determine the horizontal and vertical size of the rectangle. The small white dot in the top left alters the shape from a rectangle to an oval. The outside red dot on the right controls rotation. An object with a clear contrast with the background will track best. NOTE: If the bounding box selection gets too wide, Final Cut will try to track non-essential elements (in my case, water ripples) which will mess up the effect. Then, drag the red dots so that the rectangle closely bounds the area you are tracking. Temporarily, move the foreground object out of the way so you can clearly see the rectangle and the element you are tracking. NOTE: I decided to emulate Glinda, the Good Witch of the North, and put our fisherman in a blue bubble that moves with him. In my example, it is the fisherman in the foreground. ![]() (The green icon doesn’t show in this screen shot.)ĭrag the rectangle on top of the object you want to track. When you do, a small white rectangle, along with a green icon, appears. Then, drag the clip – NOT into the Timeline, but into the Viewer. Next, import the clip you want to move (the foreground clip) into the Browser. Make sure the Timeline playhead is positioned at the start of this background clip – or at the point where you want the object tracking to start. In my example, I have two men fly-fishing in the Berkshires in a drone clip shot by Terry Holland. To get started, add the clip containing the content you want to track (the background image) to the timeline. I was not able to get good results using point cloud. UPDATE: Based on recent tests, I recommend using Automatic or Machine Learning. On M1 Macs with an Apple Neural Engine, machine learning is greatly accelerated. Machine learning uses a bounding box to identify the reference pattern and can track people, animate or other common objects. For example, how it scales, rotates or distorts. In addition to tracking movement, point cloud will identify how the reference pattern changes from one frame to the next. Final Cut Pro uses two analysis methods (algorithms) to do the calculations for object tracking:” (Apple Help) “ Final Cut Pro analyzes the motion of the designated reference pattern. “When you drag a clip (such as a title, generator, or still image) or an effect to the viewer, Final Cut Pro suggests an object or area of pixels in the background clip (known as a reference pattern) to “lock onto” as the object moves across the viewer. With the release of Final Cut Pro 10.6, Apple added a powerful, and long-wished-for, object tracker that allows text or other elements to move in sync with objects that are moving in the frame. The 10.6.1 update finally makes this feature both useful and useable. While Premiere set the initial standard for track speed, accuracy and smoothness, the latest version of Final Cut exceeds Premiere in speed and accuracy, though tracks in FCP tend to have a few more jitters than Premiere. ![]() Depending upon the content of the clip, creating a track can even be faster than real-time. ![]() The duration of Clip 1 was 13:11 (seconds:frames), while Clip 2 ran 48:06. NOTE: The chart above illustrates the time it took to calculate an object track in two different clips. Switching to Machine Learning accelerates the track even more though the speeds you see will depend upon the computer system you are running on. In the latest release, FCP is significantly faster than Premiere when running in Automatic mode as the chart above illustrates. Speed and accuracy improved, though jitter is still a concern. UPDATE: The initial release of object tracker in FCP 10.6 did not operate reliably or well.
