Let's begin our detailed look at the user interface, the tools and attributes involved in the motion tracking process. To do any motion tracking inside Cinema 4D, we first need a motion tracker object from the motion tracker menu, and here it is. We can load the footage by selecting the motion tracker and going to the footage tab. If I click on the three dots, I can navigate, go to the folder that contains my movie or my image sequence, and just double-click on any one of the frames. The image appears squashed because it has a non-square pixel aspect ratio. Square pixel footage will load without distortion, but either way, we'll deal with this in a moment. Let's look at the rest of the attributes. Underneath the footage, you can see the lens profile. Here we will load a lens profile if we have one. If we don't we just leave it as it is. The re-sampling settings instructs a tracker to load the footage at a lower resolution. Although it's advised that you always use 100%, there are many shots that can be tracked at low resolutions. This saves time and memory especially for ultra high definition footage. For our tutorial, I'm going to use 100%. So, let's do that and you can see now the image is much crisper. Then we have the film aspect. This is where we're going to correct this squashed image. Let's just go to the side menu and select 16 by 9. And now you can see that the image is not squashed anymore. One thing to remember is that the render settings of your document get adjusted by the tracker based on the footage parameters you loaded. So, if you look at the output, it's 1280 by 1080 which was the original resolution of the squished looking image. Let's adjust this either to 1920 by 1080, or 1280 by 720 either will do. Now you can see that the image fills our viewport. Let's go and look at the next setting, frame start and frame stop. With these we can define a portion of the shot we want to track. Although the full duration of the footage will still be visible in the viewport, only the selected range will be tracked. Let's open up the navigation settings. Since this is a two-dimensional image, navigating in three-dimensional space doesn't make any sense. When the motion tracker object is selected, your navigation shortcuts will actually zoom in and pan the two-dimensional image. And at the same time, you will see that these parameters here change the scale and the two offsets. At any time you can press full footage, and the whole frame would be framed 100% in our viewport. The next two buttons Match Width and Match Height are used if your render aspect ratio and your footage aspect ratio are different. Then they will be active, and you can use either one of them. In the visibility settings you can make the footage darker so that overlaid interface elements are more visible such as trackers and tracks. Show Image, shows and hides the footage in the viewport off and on. Keeping foreground forces the footage to be in front of everything else when the motion tracker object is selected in the object manager. Create Background Object, if I click on this you will see that a background object is going to be created, a material is going to be created. And if you look in the material you can have the footage loaded in the color channel. And if I click here you'll see that the animation has been enabled. Now if I delete the motion tracker, you will see that the footage is here and it's visible in the viewport on the background object. Let me undo a couple of times, and let me delete the background object, go to the motion tracker, and when this happens, all you have to do is untwirl and go and select the solved camera. This solved camera is the camera that's going to hold all our tracking data. And because it has this protection tag that's why when the solved camera is active we can't navigate in 3D space. I'm trying to navigate here and I cannot. One thing you need to remember is that when you have the motion tracker enabled, and you have zoomed in and panned a bit in your 2D image. If then you create a background object you will see that the material applied is going to have U offsets, V offsets, and it's going to have a scale as well. So make sure before you create the background object...let me delete these...make sure that the full footage is selected. And then you create your background object. Lastly, there are a few lines of information here, what the footage name is, the dimensions, the total frames and the memory usage just for troubleshooting. Now you have an overview of the footage tab attributes and how to use them. In the next video, we will continue with the 2D tracking tab.
