xAI introduced new capabilities for the “Imagine” feature in Grok, expanding the set of tools for creating images and videos on the web platform. Users can now switch between image and video generation directly in the interface, as well as extend existing videos, allowing for the creation of longer or sequential video clips. The “Upscaling” feature, which allows for enhancing video quality to HD, is now available on the web version, although this capability is not yet available on iOS.
The “Upscaling” and “Remix” features will soon be available on Grok for iOS. The latter will allow using a video prompt to create a new image, simplifying the reuse of ideas and expanding users’ creative possibilities. This addition has already been tested by some users and has received positive feedback for its convenience in working with visual content.
The new features are especially useful for creators and developers working with visual materials and who appreciate the ability to create quality content without switching between different devices. All these capabilities are already available on the web platform, and the mobile version is gradually catching up in functionality.
xAI, under the leadership of Elon Musk, is developing Grok as a response to similar solutions from OpenAI, Google, and Meta. Interface updates and expanded control over content quality are aimed at meeting the needs of both professionals and users who are just getting acquainted with generative AI.
Grok does NOT have the ability at this time to extend videos. I don’t know where you got your info, but it’s incorrect.
They were testing a video extension feature, but it looks like it’s not fully rolled out or finished yet.
