This is a 3D tracking test with Iphone 4 video.

If you want or need to make a vfx video to Iphone 4, you must follow before these points:

- First of all you have to remove the CMOS artifact
- If you want to do 3D tracker you will need the information of the sensor and the film back size:
Iphone 4 sensor: 1/4 = 30mm
Film back size: with-3.60mm height- 2.70mm

- To do a 3D tracker you will need remove the lens distortion. For this, you will need a distortion card, you can download from this link: bit.ly/jAUIoL

I took the information here: bit.ly/9aZZJE if it helps you
