Grok Imagine Video I2V

[Core Function] Grok Imagine Video I2V animates a single starting image into a video. [Strengths] It excels at producing smooth motion from one starting frame, guided by a text prompt for the desired movement. [Best For] Highly recommended for: bringing a photo or illustration to life, dynamic product showcases, and quick cinematic motion from a still. [Limitations] Do NOT use this model for text-only generation, for resolutions above 720p, or for clips longer than 15 seconds; it requires a starting image and is limited to 480p/720p and 15s. [Routing] Use this model when the user provides exactly one starting image. For reference-driven character video, use Reference-to-Video; for text-only video, use Text-to-Video.
