Create cinematic effects in seconds
Hailuo AI adds a cinematic touch to your videos, giving them the look and feel of professional filming techniques. For instance, create short clips with classic elements like bokeh background blurs and sweeping aerial shots. These visual styles make Hailou’s outputs feel more like they were captured with a high-quality camera rather than created by software.
Whether you're adding B-roll or transitioning between scenes, this approach brings depth to your existing footage, making everything flow naturally. By automatically handling complex visual elements, Hailuo AI lets you focus on your creative concept while achieving impressive visual results.

Frequently asked questions
What’s Hailuo AI, and how does it work?
Hailuo AI is a text-to-video generator that converts written descriptions into short videos. When you enter text explaining what you want to see, the AI analyzes your prompt to understand subjects, actions, settings, and style preferences. Using AI models trained on visual data, Hailuo interprets these elements and delivers a full video according to your prompt.
Do I need technical skills to use Hailuo in Captions?
No — you don't need specialized knowledge to use Hailuo with Captions. The platform has a straightforward interface designed for users without any experience. You won't need to understand editing software or filmmaking concepts to get professional results, making video production available to anyone without formal training.
Can I edit or customize the AI-generated videos?
Yes — after generation, you can customize your videos using Captions' advanced editing capabilities. Our tools give you total control over your finished product, especially compared to image-to-video AI models with more limited settings. While the AI creates content based on your instructions, you can refine certain elements for a personal touch. For instance, add text overlays, incorporate brand elements, or combine multiple AI clips. You can also integrate automatically created audio elements with the AI Voice Generator and AI Music Generator features.
How long does it take to generate a video using Hailuo AI?
Hailuo typically produces a video in just a few minutes from submission to completion. The quick turnaround makes it well-suited to content like social media updates, timely marketing responses, or tutorial videos you need on short notice. You can also create multiple variations of your video in the time it would take just to set up the cameras for a traditional shoot.
How can I get the best results from my text prompts?
There are a few best practices to keep in mind when crafting your prompts, like using everyday language and including specific visual details. Instead of using overly technical terms, write as if you're explaining your vision to a friend. Be specific about important elements in your scene, too. Instead of writing "city street," try "busy downtown intersection with tall buildings, yellow taxis, and pedestrians crossing at the crosswalk." Focus on visual elements that can actually appear in video, and if your first result isn't quite right, try adjusting specific aspects like lighting or camera angle rather than starting over completely.
How does Captions integrate with Hailuo AI?
Captions subscribers access Hailuo AI directly from the AI Video Generator tool. This connection lets you create footage and enhance it with Captions' other features, like automatically generated captions, language options, and audio tracks, all within one creative studio.
