06/07: “Potato” 

Simply for the lack of a better name, potato was a poke at the enormous bear that is compositing. If you’ve ever tried it, you would understand how much there is behind but if not… well I’ll tell you anyways.

So in order to make this shot possible you obviously need to film the area that you wish to put your animation in. The key(as I’ve learnt over multiple failed attempts) is to ensure there are lots of areas that the program will be able to reference, more specifically on the ground. Also, avoid shadows like the plague, they really complicate things when you track. Good references are generally the corners of things that remain constant throughout the shot, obvious signs or shapes that remain constant and objects that are still. I mention “constant” a lot here because anything that is moving in your shot is the enemy as it confuses the program a lot. Also make sure you don’t use your phone and rather use a proper camera as even if the quality is good, you’re still going to have a tremendous amount of trouble trying to figure out the distortion of your lens, the depth of field, the actual distance from an object/ track and a whole new level of complexity in general that you want to avoid.

So once you’ve got your footage, you want to bring it into the program, in this case Cinema 4D and track it. Luckily this is a relatively simple process if you have good footage but if not then things become a lot more complex, in which case you should probably start watching tutorials on manual tracking (once again). Once you have a good track and you have many points that are constant throughout the footage, you can 3D solve it- which calculate the tracked objects position in space relative to the camera. After this then you need to orientate your entire scene to match the perspective of the camera.

Adding Geometry
So now that you have your scene 3D solved you can add 3D geometry and it should place it relative to the objects in the footage. In this case I made use of TurbulenceFD to make a sun and added that to the scene. Although technically it doesn’t make much sense because its a sun, I gave the object a shadow to make it appear more like it was in the world.

BOOM! Then you’re done with your 3D composite…So easy.
