When testing out the software Blender, I encountered some issues with tracking. After some feedback, I realised that this was due to me using footage I had filmed myself, footage that had very little camera movement and parallax.

 

This was due to the footage originally being filmed for colour grading purposes not 3D tracking. The troubles I encountered while tracking in Blender, was the software not being able to understand the 3D space within the footage. This was because there was little camera movement so no parallax was happening within in the shot. Parallax in terms of filming means objects in the distance moving at a slower pace across the screen than objects in the foreground. This creates a sense of depth. When 3D tracking, it is very important that the clip demonstrates enough of this in order for the software to compute the camera movement. In my shot above, there is no camera movement so Blender was under the assumption that the background and foreground where in the same space. This meant that while I was trying to get Blender to set a floor plane, it wasn’t recognising any depth within the shot, so it was impossible for me to find one.
