Milica Zec's Giant
By researching the lastest work of the VR director Milica Zec, I found this wonderful video from SVA. Zec and her teammate Winslow Porter shared their production experience of Giant, a VR story that featured in Sundance 2016. They talked about the project from the story inspiration and the technical side of VR filmmaking.
Here are some technique highlight from the video:
When bringing regular footage into a game engine, the image is flat as a plate. In order to bring a three dimensional illusion, they used a software called DepthKit, to make the footage more of a 2.5D experience.
They captured the depth data on set, then composite the data afterwards. (Inside Unreal??)
