However one space that is still a limitation to many AI video creators — myself included — is in depicting real looking facial expressions in AI generated characters. Most seem fairly restricted and troublesome to manage.
However not: right this moment, Runway, the New York Metropolis-headquartered AI startup backed by Google and others, introduced a brand new characteristic “Act-One,” that permits customers to report video of themselves or actors from any video digicam — even the one on a smartphone — after which transfers the topic’s facial expressions to that of an AI generated character with uncanny accuracy.

Precisely modeling intricate facial expressions is what led David Fincher and his manufacturing crew on The Curious Case of Benjamin Button to develop entire new 3D modeling processes and in the end gained them an Academy Award, as reported in a prior VentureBeat report.
But in the previous few years, new software program and AI-based startups resembling Transfer have sought to cut back the tools essential to carry out correct movement seize — although that firm specifically has concentrated totally on full-body, extra broad actions, whereas Runway’s Act-One is targeted extra on modeling facial expressions.

As Valenzuela instructed VentureBeat by way of DM on X: “The consistency and performance is unmatched with Act-One.”
Enabling extra expansive video storytelling
A single actor, utilizing solely a consumer-grade digicam, can now carry out a number of characters, with the mannequin producing distinct outputs for every.
This functionality is poised to remodel narrative content material creation, significantly in indie movie manufacturing and digital media, the place high-end manufacturing assets are sometimes restricted.
In a public submit on X, Valenzuela famous a shift in how the {industry} approaches generative fashions. “We are now beyond the threshold of asking ourselves if generative models can generate consistent videos. A good model is now the new baseline. The difference lies in what you do with the model—how you think about its applications and use cases, and what you ultimately build,” Valenzuela wrote.
