Recentlly I had used a After Effects plugin to export the Camera tracking info to 3DS Max. If you follow the steps it is very simple. First we need to analyze the video clip with After Effects to remove the camera shake its three axes. The program uses environmental benchmarks to analyze the movement of the camera. Scan color pixel in the image to follow and do the tracking. In the video, I used a sheet of paper with 4 red dots to help the program accomplish its task. Once the video is used, we will use the pionts track generated by the program for export to 3d software with which we feel more familiar, 3DS Max in my case. These points will be exported in the form of dummy, not renderable object of the same characteristics that could have a Null Object in After Effects. For 3DS Max to import the file from MAXScript, a small error or details to consider. The script we will create a camera in our scene with their respective keys and landmarks green by default. As I said, there is an error and you have to rotate the camera 90 degrees to take the suitable finishing orientation. I recommend selecting the camera and all imported dummies and group it before you redirect the camera.
