AI video has come extremely far within the years because the first fashions debuted in late 2022, growing in realism, decision, constancy, immediate adherence (how effectively they match the textual content immediate or description of the video that the consumer typed) and quantity.
However one space that is still a limitation to many AI video creators — myself included — is in depicting practical facial expressions in AI generated characters. Most seem fairly restricted and tough to regulate.
However now not: at the moment, Runway, the New York Metropolis-headquartered AI startup backed by Google and others, introduced a brand new function “Act-One,” that permits customers to document video of themselves or actors from any video digital camera — even the one on a smartphone — after which transfers the topic’s facial expressions to that of an AI generated character with uncanny accuracy.
The free-to-use device is step by step rolling out “gradually” to customers beginning at the moment, in response to Runway’s weblog publish on the function.
Whereas anybody with a Runway account can entry it, it will likely be restricted to those that have sufficient credit to generate new movies on the corporate’s Gen-3 Alpha video era mannequin launched earlier this yr, which helps text-to-video, image-to-video, and video-to-video AI creation pipelines (e.g. the consumer can sort in a scene description, add a picture or a video, or use a mix of those inputs and Gen-3 Alpha will use what its given to information its era of a brand new scene).
Regardless of restricted availability proper now on the time of this posting, the burgeoning scene of AI video creators on-line is already applauding the brand new function.

Precisely modeling intricate facial expressions is what led David Fincher and his manufacturing staff 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 couple of years, new software program and AI-based startups comparable to 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 concentrated extra on modeling facial expressions.
With Act-One, Runway goals to make this advanced course of way more accessible. The brand new device permits creators to animate characters in quite a lot of types and designs, with out the necessity for motion-capture gear or character rigging.

The function is concentrated “mostly” on the face “for now,” in response to Cristóbal Valenzuela, co-founder and CEO of Runway, who responded to VentureBeat’s questions by way of direct message on X.

Whereas Runway beforehand supported video-to-video AI conversion as beforehand talked about on this piece, which did enable customers to add footage of themselves and have Gen-3 Alpha or different prior Runway AI video fashions comparable to Gen-2 “reskin” them with AI results, the brand new Act-One function is optimized for facial mapping and results.
As Valenzuela informed 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 digital camera, 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, notably in indie movie manufacturing and digital media, the place high-end manufacturing assets are sometimes restricted.
In a public publish 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.
Security and safety for public determine impersonations
As with all of Runway’s releases, Act-One comes geared up with a complete suite of security measures.
