AI Video Generator

AI video generation has made the leap from novelty to production tool. In 2026, models like Kling O3 produce 1080p video with realistic motion, consistent characters, and cinematic quality that was unthinkable just a year ago. Whether you need marketing clips, social media content, film pre-visualization, or creative experiments, AI video generation is fast, affordable, and increasingly indistinguishable from professionally shot footage.

Apefx integrates 10+ video models covering both text-to-video and image-to-video workflows. Generate everything from 3-second product loops to 30-second narrative sequences with the MultiShot Master — all from a single platform.

Text-to-Video vs Image-to-Video

Text-to-Video

Text-to-video generation creates video entirely from a text description. You describe a scene — “A woman walking through a neon-lit Tokyo street at night, rain reflecting city lights, cinematic slow motion” — and the AI generates a video clip from scratch.

This is ideal for creating entirely new content when you don’t have existing visual assets. Apefx offers five text-to-video models, each with different strengths:

Image-to-Video

Image-to-video animates an existing still image into video. This is powerful because you can first perfect your image using any of Apefx’s 27+ image models, then animate the result. This two-step workflow gives you far more control over the final video’s appearance.

Model Deep Dive

Kling O3 — Best Overall Quality

Kling O3 from Kuaishou is the quality leader in AI video generation. It generates at 1080p resolution with up to 15-second duration, delivering smooth motion, accurate physics, and impressive character consistency. It handles complex prompts with multiple subjects, camera movements, and environmental effects.

Best for: Final deliverables, marketing videos, high-quality creative content.

MultiShot Master — Cinematic Narratives

Unique to Apefx, MultiShot Master generates multi-shot narrative videos with character consistency across shots. Create 9-shot sequences with different camera angles, locations, and actions while maintaining the same characters throughout. This is a game-changer for storyboarding and film pre-visualization.

Best for: Narrative sequences, storyboard pre-visualization, short films.

Cosmos 2.5 — Physical Realism

NVIDIA’s Cosmos 2.5 is a world model — it understands physics, gravity, and object interactions at a fundamental level. The result is video with remarkably natural motion, especially for scenes involving physical interactions, fluid dynamics, or object manipulation.

Best for: Product demonstrations, architectural fly-throughs, scenes requiring physical accuracy.

Vidu Q3 Turbo — Speed & Value

Vidu Q3 Turbo offers the best balance of quality and speed for everyday video generation. At 15 credits for a 4-second clip, it’s affordable enough for iteration and experimentation while delivering genuinely good quality.

Best for: Social media clips, rapid iteration, budget-conscious projects.

Lucy I2V — Lightning Fast

Decart’s Lucy I2V is the speed champion, generating image-to-video results near-instantly. While the quality is a step below premium models, the speed makes it perfect for previewing how an image will look in motion before committing to a higher-quality render.

Use Cases for AI Video

Marketing & Advertising

Generate product videos, ad creatives, and social media clips without a production crew. A/B test different visual approaches by generating multiple video variations. The Bria Product Shot model combined with image-to-video creates compelling product videos from a single product photo.

Social Media Content

Create scroll-stopping video content for TikTok, Instagram Reels, YouTube Shorts, and more. AI video is ideal for content creators who need constant video output but lack the time or budget for traditional production.

Film & Video Production

Filmmakers use AI video for pre-visualization — generating rough cuts of scenes before committing to expensive production. The storyboard generator combined with MultiShot Master creates complete visual storyboards with actual video.

E-commerce

Product videos significantly increase conversion rates. Generate product demos, lifestyle videos, and feature highlights from product photos using image-to-video models.

How to Generate AI Video with Apefx

Step 1: Choose Your Workflow

Decide between text-to-video (create from scratch) or image-to-video (animate an existing image). For maximum control, we recommend the image-to-video workflow: first generate a perfect image, then animate it.

Step 2: Select Your Model

For quick previews, use Cosmos 2.5 Fast (10 credits) or Lucy I2V (10 credits). For production quality, use Kling O3 (40+ credits). For narrative sequences, use MultiShot Master (50+ credits). Match the model to your quality needs and budget.

Step 3: Set Duration

Choose your clip duration. Short clips (3-5s) are great for loops and social media. Medium clips (8-10s) work well for product demos. Longer clips (15-30s) are best for narrative content and MultiShot Master sequences.

Step 4: Generate & Review

Generate your video and review the motion, timing, and composition. If needed, adjust your prompt or try a different model. The beauty of AI video is the ability to iterate quickly and inexpensively compared to traditional production.
