Grok Imagine Video Extend is a video continuation model designed to extend existing clips with smooth motion and coherent scene progression. It generates additional frames based on the source video and automatically appends the new footage to the original, making it well suited for clip extension, social media content growth, B-roll continuation, and creative storytelling workflows. Official-stable: stable and highly efficient, with pricing lower than purchasing directly from the official model provider.
