Yes, xAI offers video generation through Grok. The model behind it is Grok Imagine Video 1.5, which turns text prompts, still images, and reference images into short clips with native audio. It is available in the Grok apps and through the developer API, and xAI’s own Imagine API page lists text-to-video, image-to-video, and video editing as supported features.
Motion, camera movement, and physical transitions are all generated inside the same workflow. Options include aspect ratio, resolution, duration, and audio. Access spans the Grok consumer apps and the xAI API.
What Is Grok Imagine Video?
Grok is the conversational assistant. Grok Imagine is the creative suite attached to it, covering image generation, image editing, and video. Video 1.5 is the latest model in that line.
Per xAI’s documentation, the API also covers video editing on top of generation. Working creators tend to underuse this. Editing an existing clip with a text instruction is often faster and cheaper than regenerating from scratch, especially when the composition is already right, and only one element needs to change.
What Can You Create With Grok Imagine?
There are several creation modes, and the right one depends on what you already have in hand.
Text-to-Video
You describe the subject, action, setting, lighting, and camera movement, and the model renders a clip. According to xAI’s API listing, videos can run up to 15 seconds at 480p, 720p, or 1080p. Specific prompts consistently beat vague ones. A prompt that names the lens behavior, such as a slow push-in or a handheld follow, gives the model something concrete to execute.
Image-to-Video
You upload a still, and the model animates it while keeping the main subject intact. This is the most reliable mode for brand and product work because the first frame is fixed by you rather than invented by the model. The partner listing on fal.ai describes the same workflow, complete with audio.
Beyond those two, the newer model adds more controlled options:
- Reference-to-video: You supply up to seven reference images to keep characters, styles, or sets consistent. Per xAI’s parameters as republished by Vercel’s AI Gateway, this mode generates a new scene from the references rather than animating them directly.
- Video extension: You can build longer sequences from a generated clip. Third-party guides describe extension pushing total length to roughly 30 seconds, though I would treat that figure as unconfirmed until it appears in xAI’s own docs.
- Video editing: You modify elements of an existing video with text instructions.
Grok Video Generation Features and Limits
Every video model trades quality against speed and cost, and Grok is no different. The limits below are the ones that matter in practice.
Resolution and Aspect Ratio
The API supports 480p, 720p, and 1080p. Reference-to-video is the exception, with a 720p cap according to SuperGrok’s breakdown of the current xAI documentation. Supported aspect ratios are 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3, which covers landscape, vertical, and square social formats.
Duration and Frame Rate
Clip length is configurable from 1 to 15 seconds. Output runs at a smooth, standard rate, which fal’s sample response confirms with a 15-second render at 361 frames. That is the standard cinematic cadence, so footage cuts naturally into projects shot on ordinary cameras.
Reference Inputs
Up to seven reference images are accepted per request. At least one reference image or voice is required for reference-to-video mode. In my experience, three to four well-chosen references usually give tighter consistency than seven loosely related ones.
Does Grok Generate Video With Sound?
Yes. Video 1.5 generates audio in the same pass as the visuals, including dialogue, sound effects, and ambient sound. There is no separate audio model to chain, which removes a common sync problem in multi-tool pipelines.
In practice, audio breaks into four parts:
- Dialogue: Spoken lines generated from your prompt. Lip-sync is one of the areas xAI says improved in 1.5.
- Sound effects: Footsteps, glass, engines, and similar actions timed to the visuals.
- Ambient audio: Rain, wind, room tone, and city noise.
- Music: Some third-party reviews report background music, including CometAPI’s review.
If you only need silent footage, check whether your access channel offers an audio toggle, since availability differs between the app and the API.
How Long Can Grok Videos Be?
For developers, a single API request can run 1 to 15 seconds. Consumer app limits are lower and change more often. Third-party trackers report roughly 6 seconds on lower tiers and 10 seconds on paid ones, but I could not find those numbers confirmed on an xAI page, so check the app’s own limits before you plan a project around them.
Grok is built for short-form video. For anything longer, the standard workflow is to generate several clips, use extension where available, and assemble the result in an external editor. Short clips with tight prompts assemble better than one ambitious long generation.
Is Grok Video Generation Free?
Partly. On the API side, Vercel’s documentation states that free users who have not made a payment get $5 in credits every 30 days. That covers a few dozen short test clips at 480p.
Consumer access is murkier. Guides disagree on whether the free Grok tier includes video at all, and on daily limits. One July 2026 tracker, AI Business Weekly, lists X Premium at $8 per month, SuperGrok Lite at $10, SuperGrok at $30, and SuperGrok Heavy at $300. Subscription plans change frequently, so confirm current pricing inside the Grok app.
How to Access Grok Video Generation
- Web: Go to grok.com or the Grok section inside X, open Imagine, choose video, and enter a prompt or upload an image.
- Mobile: Use the Grok app on iOS or Android and open the Imagine tools.
- API: Use the xAI API with the model identifier grok-imagine-video-1.5. Some listings still show a -preview suffix, so check your console for the exact string.
Grok Imagine Video 1.5
xAI announced the model on June 16, 2026, highlighting better motion, physics, audio, and speed. According to SuperGrok’s summary of that announcement, the Video 1.5 Fast variant generates a six-second 720p clip in about 25 seconds, versus more than 40 seconds for the previous model.
Speed matters more than it sounds. Video work is iterative, and cutting wait time by roughly 40 percent means more attempts per hour, which usually improves the final result more than any single quality upgrade.
Two cautions. Third-party sources disagree on whether text-to-video is fully live in the 1.5 API or whether some surfaces are image-to-video only. And some reviewers cite a 720p ceiling while xAI’s own page lists 1080p. When sources conflict, xAI’s console and documentation are the ones to trust.
Grok Video Generation API
The API is asynchronous. You submit a request with a prompt, duration, resolution, and any image inputs, then poll for completion. Vercel’s example uses a five-second poll interval and a ten-minute timeout, which is a sensible default for production code.
Per-second pricing, as listed by ofox.ai and matching fal’s rate card:
- 480p: $0.08 per second
- 720p: $0.14 per second
- 1080p: $0.25 per second
- Reference images: $0.01 per image
A 10-second clip therefore costs $0.80, $1.40, or $2.50 at the three resolutions. Draft at 480p and render the final at 1080p. That habit alone can cut testing costs by about two-thirds.
I could not verify the rate-limit tiers in the original draft, so I have left specific requests-per-minute figures out. Check your account dashboard for your actual limits.
