Grok Imagine video generation on Mivo

What is xAI Grok Imagine and how it works?

Grok Imagine is xAI's video generation model, and its standout feature is cost. At just $0.008 to $0.015 per second of generated video, it is dramatically cheaper than any other video model on the market. This makes it ideal for high-volume use cases where cost per clip matters.

The model handles text-to-video generation, producing clips from your text descriptions. While it may not match the cinematic fidelity of Veo 3.1 or the multi-shot sophistication of Kling 3.0, it excels at producing usable video content at a price point that enables experimentation at scale.

Grok Imagine is not yet available in the Mivo Studio but can be accessed via API using the KIE model identifier grok-imagine/text-to-video. It is perfect for creators who need to generate large volumes of video content economically.

xAI Grok Imagine is available via API integration. KIE model: grok-imagine/text-to-video. Credits: $0.008-0.015 per second.

Choose the right Grok Imagine mode for your project

Standard

Cost-optimized generation at $0.008/second. Best for high-volume content, rapid prototyping, and testing at scale.

Enhanced

Slightly higher quality at $0.015/second. Better motion and detail while still being the most affordable option available.

What makes Grok Imagine a game changer

Lowest cost video generation

At $0.008-0.015 per second, Grok Imagine is the most affordable video generation model available. Generate hours of content without breaking your budget.

Scalable content pipeline

The low per-second cost makes it viable to generate hundreds of clips for A/B testing, content variations, and high-volume social campaigns.

Text-to-video generation

Generate videos directly from text prompts. Describe your scene, action, and style, and Grok Imagine produces a video clip in seconds.

Rapid prototyping

Test concepts quickly and cheaply before investing in higher-fidelity models. Validate ideas at scale without significant credit expenditure.

High-volume content strategy

Grok Imagine's low cost opens strategies that would be prohibitively expensive with premium models. Generate 50 variations of a product showcase for A/B testing, create daily social content without budget concerns, or prototype entire video pipelines before investing in high-fidelity renders.

For content teams, Grok Imagine enables a 'generate first, curate second' approach. Produce many clips cheaply, then select the best for post-production enhancement or re-generation at higher fidelity with a premium model.

Cost comparison with other models

To put Grok Imagine's pricing in perspective: generating 10 minutes of video costs approximately $4.80-$9.00 with Grok Imagine, compared to potentially $40-$100+ with premium models. This 10x cost difference makes it the clear choice for volume work.

A practical workflow: use Grok Imagine for rapid prototyping and concept validation, then regenerate the winning concepts with a higher-fidelity model like Veo 3.1 or Kling 3.0 for final delivery. This hybrid approach optimizes both cost and quality.

How to get started with Grok Imagine on Mivo

Step 1. Access Grok Imagine via API (not yet in Studio). Set up your API credentials and prepare your prompt.

Step 2. Write a clear text prompt describing your subject, action, and scene. Keep descriptions focused for best results.

Step 3. Choose Standard ($0.008/s) for maximum volume or Enhanced ($0.015/s) for slightly better quality.

Step 4. Generate at scale - create multiple variations for A/B testing, social campaigns, or content pipelines. Download and assemble as needed.

Prompt guidance

Lead with the subject and action, then define the environment and lens. If you want a cinematic vibe, mention framing and a single camera move. Adjectives are helpful in small doses - two or three well-chosen words are better than long lists.

Keep each clip focused on one action to reduce ambiguity. For multi-shot stories, reuse a short prompt skeleton and change only the subject or scene. This approach keeps tone and physics consistent across shots.

Use cases and audiences

Grok Imagine fits well into content pipelines that demand quality and flexibility. Marketing teams can iterate on product showcases, social media managers can produce platform-ready clips, and narrative creators can build story beats with consistent visual language.

For brand work, the model's ability to maintain framing and motion across retries makes it dependable for deadline-driven work. Education and editorial teams benefit from clear, readable motion for explainers and demonstrations.

Tip: capture a representative still from your render and use it as a poster image so viewers immediately see the intended look.

Aspect ratios and duration

Choose 16:9 when you need a widescreen, cinematic presentation or YouTube-first deliverables. Use 1:1 for square placements where center-weighted composition matters. Reserve 9:16 for vertical platforms to maximize screen real estate and subject emphasis.

Durations up to 10 seconds generally balance fidelity and speed. If the narrative requires more time, break the idea into multiple shots and assemble them in post.

Post-production workflow

Export final takes from Mivo and bring them into your editor to add typographic overlays, sound design, and color trims. Because Grok Imagine maintains consistent motion, cuts between takes feel natural.

For brand work, lock the look with a short LUT pass and light sharpening rather than heavy grading. Keep titles legible in vertical layouts by testing safe areas early.

Troubleshooting and refinement

If styles drift, simplify wording and prioritize concrete nouns over adjective stacks. When composition feels unstable, specify shot type and a single camera move. If subjects lack clarity, reduce scene complexity and keep one action per take.

Grok Imagine responds best to deliberate changes. Modify one parameter at a time - camera, lighting, lens, or action - and compare results side by side. This lets you steer the model toward a repeatable aesthetic without sacrificing production speed.
