Capabilities

What's new in Grok Video.

Native synchronized audio

It generates background music, sound effects, ambient audio, and lip-synced dialogue or singing in the same pass as the video, so no separate audio step is needed.

Image-to-video that stays faithful

Its strongest mode treats your source image as the first frame and animates from there, preserving the subject's identity, style, lighting, and color.

Aurora-engine motion coherence

It generates frames sequentially, keeping subjects, lighting, and camera stable across the clip, with refined physical simulation for hair, water, cloth, and micro-expressions.

Text-to-video and reference stills

Generate from a prompt alone, or pass up to seven reference images. Clips are 6, 10, or 15 seconds at 720p.

Fast with variations

Clips render in well under a minute, and it can produce several creative variations at once for quick A/B testing.

Cinematic control and flexible formats

It follows camera moves, cuts, and timing cues, and outputs across many aspect ratios suited to social platforms.

Seamless experience, excellent support

Just created 6 videos and the experience has been seamless. Wanted to write a review for appreciation — the customer support has also been excellent. They helped me in some process I was stuck in.

Vaibhav Sharma July 2026 Trustpilot

Stable, easy image & video generation

I like that I can generate images and videos without complicated setup. It works stable and is easy to use even if you are not a big developer. It saves me time and makes the whole process much simpler.
