EP 32: Advanced Motion Tracking

By - Oct 17, 2020 02:32 AM

In this tutorial, we'll learn how to take our motion tracking and FilmoraPro to the next level. We'll learn how to add contrast and isolate the desired object to get tracking points where we need it.

Need Of Advanced Motion Tracking Features

Sometimes when we are trying to do motion tracking, we might not get enough tracking points on an object that we want to follow. For example, here we want this graphic to follow the moving boat. The effect's tracking points are all over the clips, but only a few points are on the boat, which isn't enough for a decent result.

This happens because the effect will only track a limited amount of points on a clip. And it will select the ones with the best contrast which are the easiest to follow. If our object is not getting enough tracking points, this might be because it doesn't have good contrast. Or it does have good contrast but not in the areas where you want to track (like in the case of boats over here). So, there are two things we can do to improve our motion tracking.

Ways for Better Motion Tracking Results

First, we can add sharpness and contrast in the area of interest. In this case, we can use the unsharpened effect to add contrast to the edges.

We can also use curves to crank up extreme contrast levels and to make sure that the object pops out from the scene. Don't worry if this doesn't look good. This is not the final look of our video.

The second thing we can do is to isolate the object so that all the points will be focused on that area of the video. There are two ways to do this.

The first one is by using the Pan & Crop effect. Here we should deactivate the auto-zoom feature then edit the in-and-out points. And add as many keyframes as necessary to keep the objects always in frame. The result will look like the image below.

The second way of isolating the subject is by using masks and animating the paths to keep the item inside the mask at all times. Using Pan & Zoom is faster, but using the mask can be convenient with certain shapes objects. If you haven't used masking or Pan & Zoom before, we have a dedicated video for each feature links in the description.

If we try to track the object right now, we won't see any difference as motion-tracking analyzes the original footage. So, we'll need to export this clip first.

export

A fast way to do it is to drag the clip to the export panel or by right-clicking on the clip and then on Add to Export. Here, we can choose the format. We'll select the Apple ProRes 4444 Alpha Preset to get a transparent background even if that's not necessary. We'll select where to save it all and give a desired name to the file.

Once the export is over, we could click on the path directory to find the file and drag it back into the Media Panel to import it into our project.

We'll delete the effects on the first video; then, we'll place the isolated boat on the second track between the original clip and graphic. Then we'll select the graphic to make it follow the masked video.

Get More Precise Results For Tracking

In the Controls Panel, we'll change the motion from the isolated boat. And then we'll choose the selection tool again.

We can see that now all the tracking points are contained in the masked area. So, now that it's much easier to track that object, we'll select the corresponding points in the boat and make the second track invisible. Finally, we'll move the playhead back and forward to make sure that the selected points are correct.

And here, we have a much better motion tracking result. So, that a look at how to take your motion -tracking skills to the next level in FilmoraPro.
