Dolly Zoom effect

[sepideh-srj]

Has anybody tried to implement the dolly zoom effect based on this code?
We can zoom in the video now we only need to add the dolly effect which is moving the camera toward or from the scene.
I think by changing process_shift function to shift in y direction instead of x this effect can be implemented, any ideas?
