After we record a video, we have to calibrate camera and calculate our camera intrinsic. Next, we use orb-slam2 to get the keypoint camera pose and the video trajectory. When we have camera pose, we can accurately project our object (Image or GIF) to the world coordinate and get the final results.

Comparison between ORB-SLAM2 and After Effect
As we first apply SLAM to obtain camera pose, we can assume a real object in the world coordinate and project it onto camera plane. In this way, we can feel like there is a real object in somewhere. However, using After Effect cannot use 3D information and the result will be just like a 2D image on the screen.

Special Effect
Here we add rotation effect of a image.
