Hello everyone! I have created a Tutorial on how to do Sky Replacement with Blender. It shows how to use the Luma Key Node and Masks to seperate the Foreground from the Sky. It also covers 2 Point Tracking to match the Pan and Tilt of the Camera Movement in the Original Video with the new Sky.

This tutorial is basically a full conversion of the Video CoPilot After Effects Tutorial on the same topic.

I hope this will be useful to some of you.



  1. Nice tutorial. I have the feeling that the second track is too much in the foreground. If you look closely during playback, you see the light spot on the mountain behind the tracked point moving a bit. I think you can also see in the final result that there is something odd with how the sky moves as compared to the bushes to the right. The sky seems to move more than the bushes, which it shouldn't.
