2D Camera Tracking in Blender

For a compositor, tracking is one of the most fundamental skills you can have. Everything depends on it, from rotoscoping to adding lens flares, to more complex things like removing objects from a scene and advanced corner pinning. In this series, we're going to explore how you can use tracking, not as a 3D artist, but as a 2D compositor. We'll go through the different types of tracks and, using a variety of different examples, demonstrate how these techniques could be used in a real world scenario.

For a compositor, tracking is one of the most fundamental skills you can have. Everything depends on it, from rotoscoping and adding in simple things like lens flares to more complex things like removing objects from a scene and advanced corner pinning. In this series, we're going to explore how you can use tracking, not as a 3D artist, but as a 2D compositor. We'll go through the different types of tracks and, using a variety of different examples, demonstrate how these techniques could be used in a real world scenario. A working knowledge of Blender's 3D functions is expected for this series.

First we'll take a look at Blender's tracking tools and make sure you understand how they work and what is happening as you track live-action footage.

Then we'll look at few examples of single point tracking, using it to paste a decal to a wall, remove a car from a parking lot, and easily remove tracking markers from a woman's face.

After that, we'll cover offset tracking. How to track objects that go off-screen or are obscured by foreground objects.

Next up, we'll put a brand new moon in our sky using two point tracking. Two point tracking is used for tracking scale and rotation in addition to position.

And lastly, we'll go over the brand new Plane Track tool to help us achieve unbelievably easy corner pins. However, the old techniques of performing a corner pin aren't obsolete yet, and we'll explain why.

In part five, on Four Point Tracking, we demo the new Plane Track tool that's currently in development. It will be integrated into Blender soon, but for the time being you can access it via the Tomato Development Branch, linked below. Additionally, if you are interested in further tracking and compositing we recommend checking out Track Match Blender from Sebastian Koenig.
