Digital humans are playing an increasingly important role in our day-to-day lives. CG replicas of people dominate entertainment, from epic movies such as The Irishman to simple YouTube videos. Interacting with AI assistants has become second nature. And social media and news headlines are dominated by the issues surrounding deepfakes.

Joining Chris for this week’s podcast is Koki Nagano, who has become an expert in virtual doppelgangers via his research on digital humans at USC and his work at Pinscreen, a company that uses AI to supercharge the creation of 3D personal avatars from a single photo. Koki gets under the skin (literally) of what it takes to create a detailed digital human and talks about how he’s approached the uncanny valley from both sides. 

Listen to find out some incredible facts about your face — and how combining old and new technology could result in the most accurate digital humans to date.

Want to learn how to do 3D in motion graphics? EJ Hassenfratz is your man. After landing on his feet in motion graphics for NBC, PBS and ABC, EJ wound up giving a presentation for Cinema 4D company Maxon, which inspired him to learn more about the software and start creating tutorials. Today, EJ works as a freelance motion designer while crafting courses for the renowned online learning platform, School of Motion.

In this podcast, EJ gives a frank and funny insight into the world of education. He highlights some of the pitfalls of learning for free via YouTube tutorials or graduating with massive debt from college. He presents some dependable advice about taking on challenges and investing in yourself, as well as a nostalgic view of the rapid evolution of technology, animation, education and computer graphics.

"Deepfake" videos have become hugely popular online — for better or worse. This AI-powered technology results in hilarious celebrity head swaps but, as Jordan Peele demonstrated with his manipulation of Barack Obama's speech, they could play a more disturbing role in online misinformation. Computer vision scientist Wael AbdAlmageed's mission is to develop tools that can quickly detect deepfakes with a good degree of accuracy.

As digital human experts, both Chris and Wael took part in a SAG-AFTRA panel at CES and recorded this podcast afterwards. Wael explains some of the telltale signs that you’re watching a deepfake video and the approaches computer algorithms use to detect them. He also tackles digital de-aging in movies such as The Irishman and the ethics of facial manipulation. This is a fascinating look at a fight against a technology that is improving day by day.
