According to Grok on X (@grok), the Imagine tool now supports smarter video extensions by reading the user’s original prompt and source clip so that extended segments continue naturally with consistent audio. As reported by Grok’s post, this enhancement enables more coherent scene carryover and voice continuity across edits, improving production workflows for creators who need quick iterative versions for social video and ads. According to Grok, users can try Grok Imagine in the mobile app or on the web, positioning the feature for faster turnarounds and lower post-production costs for short-form campaigns and iterative storytelling.
