Recently a fulldome producer needed a solution to stabilize panorama footage and I ended up collaborating with Sebastian Koenig to make a free-gpl addon for Blender to accomplish the task.
There is a very nice post explaining how we came up with this project and the advantages of having a system like Blender Network around: [link]
The addon is on github:
Worth mentioning, this is pure stabilization based on keeping one point steady and the angle between the two points the same across the footage.
For more advanced tracking a more robust system would be needed (e.g., to select four floor points and a horizon point to give the footage always up and facing the same direction, or some damping system to allow some rotation, …). But basically the client was happy with the solution, thus so were we.
Here it is a video showing how to use the tool (@6:48 shows before/after)
Maybe in the future, with some further interest and funding this can be expanded to a more complete solution. Meanwhile if someone wants to expand the solution, you are welcome to contribute on github
Addon implementation based on the original work developed last year on Visgraf/IMPA by a different project/team (D. Felinto, A. Zang, and L. Velho): [link].
