Recently I have been working on several interesting projects involving live action footage and tracking in Blender. Here is a few examples of what that looks like.
Lets use this slideshow template as an example.
After assembling the scene, and getting the camera and lighting set properly so that there is minimal movement and changing contrast it is fairly simple as far as filming. The important thing is to make sure the tracking texture is blocked as little as possible while swiping through the slideshow.
Here is an example of the footage before tracking and compositing.
Using the crosses as tracking markers, it is then fairly east to track the element movement in Blender to the footage motion. The compositing step is important not only for color grading, but also for needed effects. For example for this project I needed to remove the Samsung branding from this phone. Using a mask and a single carefully re-painted frame I was able to remove it efficiently.
