review of DMProjector from pineappleware has a set of fulldome tools. Trial versions are available for download, unfortunately the contact email for pricing info and purchase elicited no reply. The trial versions are limited to 1K resolution. Passable for our dome, not optimal. The tools save Alpha channel, so stitching together multiple frames with different images on them easier.

DMPanorama has nice features like fill upward, for filling the "sky" part of the panorama automatically.

DMProjector exports a single image (or an image sequence) to a specific part of the dome. Perhaps I can try it for video sequences - doing this would be faster than rendering in blender.

Field of view in DMProjector can be specified either vertically or horizontally. Giving a  vertical field of view double the altitude makes the image just touch the horizon at the bottom, since the altitude is defined at the centre of the image. Anti-Aliasing with a sample level of 3 gave good results for me.

Choosing a panoramic image and a 120 degree field of view gave similar results from DMProjector as with DMPanorama, except without the "fill upward". But DMProjector doesn't seem to do panoramas bigger than that properly.
