Grok Imagine Video 1.5 Lite

Grok Imagine Video 1.5 Lite is a cost-efficient video generation model developed by xAI designed to transform text prompts and still images into dynamic video clips with native synchronized audio. Distilled from the flagship Grok Imagine Video 1.5 architecture, this lightweight variant offers a budget-friendly tier optimized for high-volume workloads, rapid prototyping, and social media content production.

Capabilities and Specifications

The model supports both text-to-video and image-to-video modalities, producing short clips ranging from 1 to 15 seconds in duration. Output is available across multiple resolutions including 480p, 720p, and 1080p, and spans seven different aspect ratios such as widescreen (16:9), square (1:1), and vertical formats (9:16). By generating sound effects, ambience, and dialogue natively in the same pass as the visual output, it streamlines standard multimedia creation pipelines.

Usage and Workflow Tips

Designed for rapid iteration, the model omits heavy reference features like multi-image keyframing found in the full version to maximize generation speed and reduce per-second operational costs. When constructing text prompts, users should detail the subject, motion, camera framing, and lighting environment clearly. For image-to-video workflows, providing a well-defined starting frame allows the model to lock in character appearance and style while concentrating entirely on natural motion progression.
