For the opening sequence of the film, we had to create the wispy energy and to make it appear that the girl is getting pulled out the window. We had to build a clean plate of the room to replace the green screen platform she is lying on, we then added the 3D energy waves and created 3D debris flying around the room.

For many sequences, we had to create the effect of the witch moving fast and teleporting

Another sequence where the witch is using her energy tentacles

For this shot, we had to extend the end of the hallway, replacing the green screen. This was a difficult shot to track due to the camera movement.
