You probably already know this but in case not, here you go:
There’s two types of pans: inter-zone pans and intra-zone pans
Inter-zone pans are just pans to different zones:
@pan to zone # in T
@pan to zone 2 in 3
This means the camera will pan (slide) to zone 2 from the current zone it’s in, and this pan will last 3 seconds.
It doesn’t have to be three seconds. It can be any number of seconds you want it to be.
I talk more about them here: HOW TO: Stage Direction
Now, onto Intra-zone pans
These are pans that occur within a single zone. (So if you’re in zone 1, these pans will take place in zone 1 only. Want to pan to another zone? No problem, you need to use an inter-zone pan mentioned above)
The generic code for it:
@zoom on X Y to % in S
In order to achieve an intra-zone pan, You would zoom from one X Y coordinate to another at the same magnification %.
What this means is that your X and Y values can end up being different however the % is the same.
@zoom on 160 400 to 200% in 2
So, the 160 could change to a different number and so can the 400, however the 200% remains the same.
