Chroma Key Footage with Interactive Graphics
Here’s more on-location footage shot in a small room. This time, we shot chroma key footage on a portable green screen. Here are the before and after images:
Since the movement was fast and youthful, we shot footage of lots of flailing arms and flipping hair (not the best source material for footage that we would later need to key).
We keyed the footage and then added graphics that appear to interact with the talent – moving around them, casting shadows on them and appearing to grow from their actions. The 3D motion graphic elements were rendered out in a manner which allowed us to move the graphic elements in front of and behind the actors seamlessly. We also motion tracked some of the shots allowing us to match the movement of the graphics to the actors movements.0
