Motion tracking allows you to track different objects in order to add a
moving title or other effects. In this tutorial we'll track two different boys
playing football and motion track moving titles that follow their movement. Before
we get started, if you're watching this video on YouTube you'll find a link in
the description below that will take you to our tutorial page on the Discovery
Center. Here you can download a written copy of this tutorial to follow along.
Let's get started. I have VideoStudio opened up under the Edit tab and I'm
going to drag the video of the boys playing football onto the Video track on
my timeline. Then, with my clip selected, I'll click on the Track Motion icon from
the toolbar. The first thing we need to do is drag the red tracker to the first
boy that we want to track. You might also want to change the tracker type to "Set
Tracker as Area" if you want to track a larger area and not just pinpoint one
spot. Then I'm going to uncheck "Add Matched Object" which is useful for
adding a matched image or video, as in this video we're going to add a moving
text later on. Now let's click Track Motion and you'll see that a small box
follows and tracks the boys movement. You can see that the motion tracker has
continued tracking even after the boy has left the shot, so we need to fix this.
Let's drag the scrubber to the point where the boy disappears on the screen
then click Track Out.
Now let's go down and click Rename Tracker and name this "Jack". Next we're
ready to track the other boy playing football. So let's click the plus icon to
add a new tracker. This time we'll drag the tracker to pin this boy here, and
once again we'll uncheck "Add Matched Object" and then click the Track Motion button.
If we drag our scrubber to about four seconds into the clip we can see that
the tracker stops once another boy goes in front of the boy were tracking. So
we're going to click the Track Out button again to stop tracking here.
Now drag the scrubber to a point on the clip where the boy re-enters the shot and
once again, click the plus icon to add a new tracker. Drag the tracker on top
of the boy then uncheck "Add Matched Object". Now click the Track Motion icon
again and you'll see we've continued tracking the boy after he reappears.
We can click on the Rename Tracker icon again to rename these trackers "Mark 1"
and "Mark 2" if we want to make any adjustments later on.
Then click OK. You'll see that motion has been tracked on our clip on the video
track indicated by this white icon and these light blue lines showing where we
have tracked motion within the clip. Now I want to add moving titles with the
names of the boys that we've just tracked to follow them as they play
football. We'll first double-click on the Title track on our timeline then double-
click on the preview pane where we'd like to add our title and I'm going to
type "Jack" for the first boy. Of course we can adjust the font type, size
and color as we'd like, and also extend the length of the title to match the
motion by clicking on the title then hovering our mouse over the edge and
clicking and dragging it until the point on the clip where Jack disappears.
Now what we want to do is match this title to the motion we've tracked in our
clip. So we're going to right-click on the title, select Motion Options, then
Match Motion. Now make sure that the right tracker is selected: in this case
we'll select Jack. Here you can adjust the position of your title by
clicking and dragging it on the preview pane. We can also change other settings
like size, rotation or the opacity level. Now very important: for any changes you
make to the settings on the first keyframe, you'll have to right-click on
the first keyframe and select Copy and Paste to All. This will ensure that the
title customizations are the same throughout the entire clip. Once you're
done click OK. Now we need to repeat this process with the second boy.
Right-click on the title track and select Insert Track Below to add a second title
track. Then double-click on the new title track and double-click on the preview
pane to type in Mark's name. Once again, we'll make any customizations
to the font type and color, then adjust the length of the title.
Then right-click, select Motion Options then Match Motion. This time we'll change
the tracker to Mark and again, for any customizations we make to the title
position or style we'll right-click on the keyframe to copy and paste to both
keyframes. Then click OK>
Finally, we'll right-click on the Mark title and paste it onto the title track
under the motion we created when Mark reappears from behind the other boy so
we can use the same font and style for Mark's second tracker. Then we'll adjust the
length of the title so it matches the full length of the motion we tracked.
Then right-click, select Motion Options, Match Motion and then make sure Mark 2
is selected. Then click OK.
And now when we preview our video you'll see how we've created two titles that
follow the boys' motion as they play football. If you're watching this video
