When Los Angeles-based actress and interior designer Ashley Martin Scott responded to a casting call for “mom and baby” back in April 2015, details were scant. “I pretty much came into it blindly, not knowing what to expect, aside from ‘a mom and a baby,’” Scott said. “And that it was something about leaving a message for your child in the future and I thought, ‘That sounds fun.’” The casting call led her to the 8i studios, then in Culver City, California. That’s when Scott discovered this wasn’t a typical casting call: she and four-month-old Reese were being turned into holograms, a term that’s used (and sometimes overused) to describe volumetric video. 8i was looking to build up its repository of holograms, and a mom-and-baby clip seemed like a good idea for relatable content. Scott’s first hologram taping led to her crying in a VR headset, and became what the company’s chief executive called a “watershed moment” for the then-fledgling company. 8i’s soundstage is made up of a massive, high-ceilinged green screen, with 41 off-the-shelf cameras aimed at a small circle in the center of the stage. These are the cameras that have captured Ashley and baby Reese, tigers and llamas, NBA stars, wrestlers, actor Jon Hamm, and more. All of the raw image data from the cameras is sent to a computer, where 8i’s proprietary software fills in any data gaps and renders the video. Then it spits out a short, holographic video vignette, one that can be viewed in either a VR headset or in 8i’s mobile app, Holo. It’s a highly technical process, one that 8i — and other companies — have been trying to perfect as volumetric content has emerged as the “next big thing” in video. But for Scott, her first 8i experience was more emotional than technical. When she first put on a VR headset to view her finished holograms, she started to cry. “Everybody wants holograms of their kids.” Scott attributes her reaction partly to the realness of the volumetric video, which lets you walk around a digital object, get close to it, peer at it, and in a limited way, interact with it. She recalled reaching her arms out, as if to hold her child, and experiencing “phantom” limbs; she knew she was moving
