About model

Grok Imagine Video: AI Video Generator with Native Audio Sync

Grok Imagine Video from xAI (the Grok team) is a next-generation multimodal video generator with built-in synchronized audio: videos come with dialogue, sound effects, and music already integrated. This native audio synchronization is the standout feature that sets it apart from competitors who often generate silent video.

Core Capabilities

Text-to-Video (T2V): Describe a scene in text, and the model generates 480p or 720p video from 1 to 15 seconds long. Perfect for commercials, previsualization, and concept art.

Image-to-Video (I2V): Upload a still image (typically a key frame), and the model brings it to life with fluid motion and synchronized audio.

Video-to-Video (V2V): Restyle existing video, change visual tone, or alter motion patterns.

Supports aspect ratios 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3.

Audio Synchronization — The Killer Feature

Grok Imagine generates video with synchronized sound out of the box:

— Dialogue and character speech sync with lip movement (lip-sync)
— Music is selected contextually to match the scene
— Sound effects are added intelligently (footsteps, impacts, ambient)
— No need to source audio or music separately

Output Formats and Duration

Exports to MP4, WEBM, or MOV. Standard T2V and I2V support 1–15 seconds; V2V runs 2–10 seconds to maintain quality.

Pricing

Transparent per-second pricing: 480p T2V costs roughly 4–5 RUB/sec, 720p slightly higher. Image-to-Video adds a small premium; V2V is more expensive due to source analysis overhead.
