Blender Motion Tracking: 2D & 3D reconstruction test

Two experiments I did with the new Blender Motion Tracker. The
lightsaber test is a simple 2 point tracking exercise. The
reconstruction is only bi-dimensional: I used the shape keys to manually
adjust the saber’s length. The second one is a classic camera tracking
test, with 3D reconstruction.

Both shots were filmed with my Galaxy Tab 10.1 (the highest-resolution
camera I have!). It worked quite well, but I discovered two problems
with it. Firstly, I couldn’t find anywhere its focal length (required
for camera tracking). At last, I set it to 45mm. The other problem is
that Galaxy camera apparently duplicates some frames. It puzzles
Blender Tracker, which understandably doesn’t expect to find two
identical pictures.

Another thing I learned is that it’s safer to convert a video file into
its individual frames before tracking. This way Blender seems to work
better and you can delete duplicate frames as well.

Playing with motion tracking is funny, so I hope these tips can help
you. And thanks for watching !
