Panning, tracking during time lapse...

[eco_bach]

Hi
Not sure if this is the correct forum, but would really like to know how to do quality tracking panning shots for time lapse movies.

Do I need to invest in expensive tracking gear such as

Or can I achieve almost as good results in post using 'pan and scan' techniques?

Wow, $800! That seems really inexpensive.

The problem with trying to do it in post is occlusion. In other words,
when a camera actually moves, you see objects being revealed or hidden
as the camera moves past nearby objects.

You can simulate the effect in post (it's part of the process of converting a 2D film to "3D"),
but it's a ridiculous amount of work–mostly rotoscoping–and the effect is still not as good as reality.
