Just downloaded the latest version of Autopano Video Pro 3 Alpha.
Trying out the new D.Warp tool and I must say it is very cool. I only wish there was more control over it.

Here is a frame showing a person in the seam.

And here they are after D.Warp has been applied.

Looks very good. It does take some time to apply it to your footage.

Here is a 20 second clip using D.Warp inside the Catholic Church at Mission San Jose.
