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 continues to be a limitation to many AI video creators — myself included — is in depicting lifelike facial expressions in AI generated characters. Most seem fairly restricted and tough to manage.
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 report 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 instrument is steadily rolling out “gradually” to customers beginning at the moment, in response to Runway’s weblog put up on the function.
Whereas anybody with a Runway account can entry it, it is going to 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 12 months, which helps text-to-video, image-to-video, and video-to-video AI creation pipelines (e.g. the consumer can kind 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.
As Allen T. remarked on his X account “This is a game changer!”
It additionally comes on the heels of Runway’s transfer into Hollywood movie manufacturing final month, when it introduced it had inked a cope with Lionsgate, the studio behind the John Wick and Starvation Video games film franchises, to create a customized AI video era mannequin based mostly on the studio’s catalog of greater than 20,000 titles.
Simplifying a historically complicated and equipment-heavy inventive proccess
Historically, facial animation requires intensive and sometimes cumbersome processes, together with movement seize tools, guide face rigging, and a number of reference footages.
Anybody occupied with filmmaking has doubtless caught sight of a number of the intricacy and issue of this course of up to now on set or when viewing behind the scenes footage of effects-heavy and motion-capture movies corresponding to The Lord of the Rings sequence, Avatar, or Rise of the Planet of the Apes, whereby actors are seen lined in ping pong ball markers and their faces dotted with marker and blocked by head-mounted apparatuses.
Precisely modeling intricate facial expressions is what led David Fincher and his manufacturing workforce on The Curious Case of Benjamin Button to develop complete new 3D modeling processes and finally received them an Academy Award, as reported in a prior VentureBeat report.
But in the previous few years, new software program and AI-based startups corresponding to Transfer have sought to scale 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 complicated course of much more accessible. The brand new instrument permits creators to animate characters in a wide range of kinds and designs, with out the necessity for motion-capture gear or character rigging.
As a substitute, customers can depend on a easy driving video to transpose performances—together with eye-lines, micro-expressions, and nuanced pacing—onto a generated character, and even a number of characters in numerous kinds.
As Runway wrote on its X account: “Act-One is able to translate the performance from a single input video across countless different character designs and in many different styles.”
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.

This shift permits creators to convey their characters to life in new methods, unlocking the potential for richer storytelling throughout each live-action and animated codecs.
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 corresponding to Gen-2 “reskin” them with AI results, the brand new Act-One function is optimized for facial mapping and results.
As Valenzuela advised 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 rework narrative content material creation, significantly in indie movie manufacturing and digital media, the place high-end manufacturing sources are sometimes restricted.
In a public put up 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 outfitted with a complete suite of security measures.
