This is due to shadows created by the director! We'll look at improving our lighting set up and focus for future projects. You'll notice that the lighting changes a lot between frames. (Most people these days would be referring to a higher resolution if they said HD, but this is the definition.) We found that it's possible to export photos and videos at 1080 x 720 which is the lowest resolution for HD.
The default video export is at 640 x 480 which is pretty low res these days. We exported the resulting animation as a mp4 video (there are lots of options for export formats and settings, this is just using the default.) You hear a camera shutter sound every time Hue Animation Studio takes a picture so this approach works really well. Next, we rigged up a momentary touch switch as the input to the MaKey MaKey so you can just press a button to take a picture.
