This is a reel from Mackevision, showing the visual effects they did for season 4 of Game of Thrones. I wasn’t expecting all the boats to be fake.

This reel does a better job than most in showing the process and how all the different elements fit together. Also interesting to see how much the digital greebles make everything seem way more realistic.

Update: And here’s another reel of VFX from season 4 by Rodeo FX.
