Hi Andrew / @facherty - I saw your post about VLM over on …. that other place.
In relation to using POI and camera accuracy, have a look on this post : Some notes on using Litchi : which has some related info, that relates to camera pitch exactly as it does to camera direction as it passes POIs.
There’s also this thread : Litchi chit-chat … What’s Litchi? Should I use Litchi? : that does what it says on the tin, but also contains snippets of useful info.
