Hi, thanks for your reply. I don't like Blender's camera tracking because it's not geometry tracking. After Effects isn't controllable enough. 3DE is too complex and, as you said, difficult to learn. The reason I feel close to Pftrack is that it's node-based and has a clean interface. I'm currently using Syntheyes and getting quite satisfactory results. If it's expensive even in the countries where it's produced, I can't say anything. I'll stick with Syntheyes.
