AI Video Generator - Create Videos from Text or Images

Generate videos from text prompts using 6 AI models - Veo 3.1, Kling, Minimax, Luma Ray 2, and Grok. Compare results and pick your favorite. Transform images into videos with AI.

How Text to Video Works

1. Write Your Prompt - Describe the scene, action, style, and camera movement you want. Use the negative prompt to exclude unwanted elements like blur or distortion.
2. Choose Model & Settings - Pick from 6 AI models - each with different strengths, speeds, and price points. Set your aspect ratio (landscape, portrait, or square) and video duration (4 to 8 seconds).
3. Generate & Download - Hit Generate and your video will be ready in 2-5 minutes. Preview it directly in your browser, then download as a high-quality MP4 file ready for any platform.

How Image to Video Works

1. Upload Your Image - Upload the photo or image you want to animate. JPEG, PNG, or WebP up to 10MB. The AI will use this as the starting frame or visual anchor for your video.
2. Describe the Motion - Write a prompt describing how you want the image to move - camera pans, subject motion, environmental effects. The AI animates your still image based on your description.
3. Pick a Model & Generate - Choose from models ranked by image-to-video quality. Kling, Luma, and Minimax use your image as the actual starting frame. Generate and download your animated video.

Tips for Better Video Prompts

• Describe Camera Movement - Specify how the camera moves: "slow pan left to right", "dramatic zoom into the subject", "tracking shot following the character", or "static wide shot" for a locked-off frame.
• Specify the Action Clearly - Tell the AI exactly what moves and how. Instead of "a dog in a park", try "a golden retriever sprinting across a sunlit meadow, ears flapping, then leaping to catch a frisbee mid-air."
• Set Mood with Lighting - Lighting transforms the entire feel. Try "golden hour backlight with lens flare", "moody overcast with soft shadows", "neon-lit cyberpunk alley at night", or "bright flat studio lighting."
• Use Reference Images - Upload a reference image to guide the AI's starting frame. This works especially well for product shots, character consistency, and scene extensions where you want visual continuity.
• Draft with Budget Models First - Start with Minimax Video (15 credits) or Grok Video (30 credits) to test your prompt and refine it. Once you're happy with the composition and motion, regenerate with Kling Video or Veo 3.1 for the final version.
• Use Negative Prompts - Add a negative prompt to steer the AI away from common issues. Try "blurry, distorted faces, flickering, choppy motion, watermark, text overlay, low resolution" for cleaner output.

Frequently Asked Questions

How does AI video generation work?

There are two modes: Text to Video and Image to Video. In Text to Video, you write a prompt describing the scene - subjects, setting, action, style, and camera movement. In Image to Video, you upload a photo and describe how you want it to animate. The AI model generates a unique video clip frame by frame. The entire process takes 2-5 minutes depending on the model, duration, and resolution.

What AI models are available and how do they differ?

Six models are available across four providers: Minimax Video (strong motion and physics, the most affordable at 15-28 credits), Luma Ray 2 (smooth camera work at 28-55 credits), Grok Video from xAI (creative, expressive style at 30-50 credits), Veo 3.1 Fast from Google (quick drafts at 35-65 credits), Kling Video from Kuaishou (excellent faces at 45-90 credits), and Veo 3.1 from Google (native audio + cinematic quality at 100-200 credits). Each model interprets prompts differently, so try the same prompt on multiple models to compare results.

How many credits does video generation cost?

Credits vary by model and duration. Minimax Video starts at just 15 credits (4s). Luma Ray 2 costs 28-55 credits. Grok Video costs 30-50 credits. Veo 3.1 Fast costs 35-65 credits. Kling Video costs 45-90 credits. Veo 3.1 is the premium tier at 100-200 credits with native audio. Longer durations cost more. See the pricing comparison table above for the full breakdown.

How long does video generation take?

Most videos take 2-5 minutes to generate. Veo 3.1 Fast and Grok Video tend to be quicker (1-3 minutes), while Kling Video and Veo 3.1 standard take longer due to higher quality processing. A progress indicator shows estimated time and generation phases while you wait.

What aspect ratios and durations are supported?

Three aspect ratios are available: Landscape (16:9) for widescreen, Portrait (9:16) for mobile and social media, and Square (1:1) for social feeds. Most models support all three aspect ratios, while Veo models support landscape and portrait only. All models support 4-second and 8-second durations.

Can I use generated videos commercially?

Yes. Videos you generate are yours to use for personal and commercial purposes, including marketing, social media, products, and publications. Each AI provider (Google, xAI, Kuaishou) has their own usage policies, so review those for specific commercial use cases like broadcasting or large-scale distribution.

What is image-to-video and how does it work?

Image-to-video lets you upload a photo that the AI animates into a video clip. Switch to the "Image to Video" tab, upload your image, then describe the motion you want. Models like Kling, Luma Ray 2, and Minimax use your image as the actual starting frame for the best results. Veo preserves the subject from your image, while Grok uses it as a softer reference. Upload any JPEG, PNG, or WebP image up to 10MB.

What are negative prompts and when should I use them?

Negative prompts tell the AI what to avoid in the generated video. Common entries include "blurry, distorted, flickering, low quality, watermark, text overlay." They are optional but useful when you're getting unwanted artifacts or visual elements in your results. Think of them as guardrails that steer the AI away from specific problems.

Why did my generation fail or get blocked?

Generations can fail for a few reasons: your prompt may have triggered the AI model's built-in safety filters (try rephrasing without sensitive content), the model may have hit a temporary capacity limit (try again in a minute), or a network error occurred. In all failure cases, your credits are automatically refunded.

What happened to OpenAI Sora?

OpenAI announced that Sora is closing down and is no longer available for new video generations. All Sora models (Sora 2 and Sora 2 Pro) have been removed from our generation options. We recommend Minimax Video or Kling Video as alternatives for similar quality results, or Veo 3.1 for premium output with native audio. Your credits can be used with any of our 6 available models.

How is this different from using Veo, Kling, or Runway directly?

Prompt Reverse gives you access to 6 AI video models from 4 different providers in one place - Google Veo 3.1, Kling, Minimax, Luma, and xAI Grok - so you can compare outputs on the same prompt without managing multiple accounts. Plus, it's integrated with our full suite of AI tools for image generation, editing, analysis, and more. No separate signups or API keys needed.
