Ehm, sorry, not just to defend my baby, but that "Lag" is just a bit of fumbled cutting on my side. If you mean the rappid changes of viewpoint there. I seem to have accidentally switched the a few closeups. And I cut out some scenes where Kitin body obscured the view completely.
This results in a lag-like hopping of camera-view.

And if you mean the slight "hopping" of the camera while zooming out from the ledge, well... try it out. Is your Indexfinger nimble enough to get a smooth zoom out to that distance? To turn the mousewheel eough times, fast enough
I tell you, it´s HELL
And I couldn´t just tell all the Homins there:
"Allright, I fumbled the zoom in this scene. All back to start.
Yeah, the Kitin too please.
Big Mama, go back to your corner and prepare to get attacked again.
Ah, and you homins, try not to get killed again so fast, would you?"
Sorry.
