February 7, 2017 Motion tracking

I have moved on to learning to do motion tracking in Blender. This was initially one of the main reasons I have put so much effort into Blender even though I am just now getting to it. I felt that it was best to have some modeling and animation skills first, so with that out of the way, it is finally time to buckle down on this skill.

It isn’t so much that it is hard to do, but it sure is time consuming. At this point, I’m guessing I have put at least eight hours into this first rather short clip of drone footage. Obviously, this isn’t economical going forward, unless I can find a way to drastically speed the process up. I was really hoping that I could use this regularly for overlays of drone footage and horseshoeing videos, but I’m not so sure now. I’m just getting started with learning motion tracking, but I’m not seeing any way to make that speed possible.

Each track has been hand tracked because automatic tracking hasn’t been successful at all. There is a steady drift on most tracking points that need to be managed and many times the tracking point is lost every several frames. So, for now it is frame by frame, and so far I have over 50 tracks with probably at least a dozen or more left to do. Even still, I don’t know if solving for the camera will be successful, especially since I am using a GoPro Hero 4 Black, which has a significant fish eye effect that motion tracking can have trouble with. I have seen where it is possible and I will take the necessary steps to ensure the highest probability of success. Not only that, but this clip has some camera rotation to solve, which can further complicate the solving. Again, I have taken all that into consideration, and believe it is possible too. Painstakingly hand tracking is going to be the key at this point.

In other news, we are talking about finally getting serious about starting Chicken Manor. lol We’ll see…
