Purpose
Grok Video is an online AI short video generation tool, mainly aimed at users who need to quickly generate short clips from text or a single image. The page states that it uses Grok Imagine 1.5, can generate realistic-style AI videos, and allows users to control camera angle, duration, and resolution.
Main Capabilities
- Text to video: Generate a short video directly from a text prompt, suitable for creative scenarios where there is not yet a starting frame.
- Image to video: Upload a reference image (JPEG, PNG, WebP supported), bring this still frame to life, and preserve the subject and overall composition as much as possible.
- Visual control: Duration can be selected from 1 to 15 seconds, and resolution can be selected as 480p or 720p. The official website description also mentions options such as 5 seconds / 10 seconds and 720p / 1080p; the specific selectable range is subject to the actual page.
- Credit cost preview: Before submitting a generation task, you can see the calculated credit consumption; the page example shows the current selection as 19.2 credits.
- History and download: After generation is complete, you can preview the result and view and download completed image and video tasks in private history.
- Multiple model entry points: The page lists image and video models such as Grok Imagine Video 1.5 Preview, GPT Image 2.5, Grok Imagine Image 2.0, Nano Banana 2.1, MiniMax H3, Gemini Omni 1.1 Flash, Seedance 2.5, and Seedream 5.0 Pro.
- Example prompt reuse: Provides original text-to-video and image-to-video examples (such as driving through a city in the rain, a zero-gravity greenhouse, a push-in shot in a lantern alley, etc.), whose prompts can be reused.
How to Use
- Choose a generation mode: Select either text to video (suitable for text ideas) or image to video (suitable for an existing still frame).
- Write a prompt or upload an image: Describe the subject and action; if the selected mode requires it, upload a reference image.
- Set duration and resolution: Choose a duration from 1 to 15 seconds, and 480p or 720p output.
- Generate, preview, and download: After confirming the credit cost, submit the task, preview the completed clip, and download and save the result.
