Using a combination of traditional VFX techniques and its proprietary face-swap- ping technology, Charlatan, Digital Domain was able to take Beckham deep into the future without a 3D scan. This for the new "Malaria Must Die – So Millions Can Live" short, produced by RSA Films Am- sterdam, to drive global awareness around ending this deadly disease. In the short, an older Beckham is making a speech on the day malaria has ended, send- ing a message of hope from years down the line. As he speaks, the years fall away, leaving the Beckham of today to make this final plea – a malaria-free future is possible in our lifetimes, but only if we keep up the fight. To deliver this transformation, Digital Domain received performance clips of both Beckham and an older stand-in delivering the speech. These reference materials were then fed into Charlatan, a technology that uses machine learning and video footage to produce realistic digi-doubles. Because Char- latan is non-invasive, the system could be completely trained through principal photog- raphy, allowing Beckham to film his scenes without an intensive data capture shoot. To give artists a running start, Charlatan intelligently merged the performances of current-day Beckham and an older stand-in to automatically project what an older Beck- ham would look like giving the same speech. Through this process, key age characteristics like skin motion and specific wrinkles were woven into the likeness, while keeping all of Beckham's unique attributes. This shaved months of sculpting time off the process and helped the team have a natural-looking nose, laugh lines, and other hard-to-animate features nearly finished before the tradition- al techniques came into play. "As an artist, what you are really looking for is control. Details matter when it comes to faces, especially when your subject is known all over the world," says Dan Bar- tolucci, VFX supervisor at Digital Domain. "It became clear that blending attributes from an older face was going to give our team the nuances they needed. To facilitate this, we looked to Digital Domain's in-house R&D team, Digital Humans Group, which has a long history of creating tools that push the boundaries of facial realism. They came through yet again, inventing a process that is the perfect blend of technology and artistry." With a high-res base to work from, artists began applying a human touch to the face, defining key parts of the aging process with the help of traditional techniques, like matte painting and compositing. As aging cues are highly subjective, artists needed full rein over the hair, skin, and beard to create a believ- able transformation. Unlike most methods, though, the team didn't have to create a sin- gle bit of 3D geometry to do it, helping them turn out a final asset in under eight weeks. "We all knew this was an ambitious project. Nailing the inimitable detail for David Beckham's older look was critical," says Ross Plummer, managing director of Ridley Scott Creative Group. "What Digital Domain has created is world-class and captivating. We needed that 'wow' factor to break through the noise." "In visual effects, we oen get to create remarkable, memorable images, but we rarely get to apply our cra to such a note- worthy cause," says John Fragomeni, global VFX president at Digital Domain. "We feel honored we were able to contribute to this project and help advance a story that needs to be told."
