Grok-imagine
Grok Imagine is an AI video generation tool available via LuminaMind that transforms detailed text prompts and reference images into cinematic video clips with native audio in seconds. Built on xAI's Aurora autoregressive mixture-of-experts architecture, Grok Imagine generates video and audio in a unified pass to produce synchronized sound effects, music, and ambient audio without separate post-production. It is intended for creators, storytellers, marketers, and developers looking to rapidly prototype or produce short-form cinematic content across formats and platforms.
The interface supports multiple generation modes (Fun, Normal, Spicy), multi-image references (up to 7 images), flexible aspect ratios, and preset resolutions and lengths. Grok Imagine is presented alongside other cutting-edge models on LuminaMind such as Veo 3 and Sora 2 and is optimized for fast iteration with generation times around ~30 seconds per video with audio.

Native Audio Synthesis
Generates synchronized audio including background music, sound effects, ambient noise, and dialogue in the same unified generation pass as the visuals, ensuring natural audio-visual alignment.
Lightning-Fast Generation
Produces high-quality video with native audio in near real-time (approximately 30 seconds per video), enabling rapid iteration and prototyping.
Aurora Mixture-of-Experts Model
Powered by xAI's Aurora autoregressive mixture-of-experts network that dynamically activates specialized sub-networks for tasks like motion physics, style consistency, and audio coordination.
Multiple Creative Modes
Three creative modes—Normal, Fun, and Spicy—give users control over style, creativity, and content filtering intensity to match project needs.
Multi-Image Reference Input
Accepts up to 7 reference images to guide character consistency, scene composition, and visual style across generated videos.
Flexible Aspect Ratios & Resolutions
Supports aspect ratios such as 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1 and offers multiple resolution and length presets for social and cinematic formats.
Temporal Latent Flow for Motion Consistency
Uses a 4D latent representation (3D space + time) to ensure consistent lighting, shadows, and stable textures across frames, reducing flicker and temporal artifacts.
Unified Audio-Visual Generation
Audio and video are generated together using shared latent representations so that sound effects, music, and dialogue naturally sync with visual events.
Video Reframe Tool
Reframe existing videos (up to 30 seconds, max 100MB) to different aspect ratios supported by the platform without re-rendering content from scratch.
Pricing
Free credits are available after signing in (exact credit amounts and paid tiers not listed on the page).
