With the rapid evolution of artificial intelligence, new software has arrived on the market, revolutionizing the audiovisual creation process.

Now, it’s possible to generate complete videos from text, add near-natural voiceovers, create animations, and even simulate cinematic effects.

However, most of these software require payment to use their more advanced features, and the question remains: which one brings the best results?

Nothing better than an user opinion, so our team tested three options that are popular on the market: Hailuo, Kling and Google Veo 2 and Veo 3.

In this article, we’ll highlight what we like, the strengths, and challenges we encounter with each of them. Check it out!

The AI-Driven Audiovisual Revolution

Before we dive into the tools, it’s important to understand why AI has become so relevant in this scenario.

First of all, it offers agility. Creating a video that used to take days can now take just a few minutes or, depending on the complexity, a few hours.

Furthermore, production costs have plummeted, as much of the process is automated.

Teachers, content creators and small entrepreneurs now have access to resources that were previously restricted to large capitals.

But it’s not just about savings or speed. Artificial intelligence also broadens the scope of what’s possible to produce.

Those who prefer to remain anonymous now have avatars that are difficult to distinguish from real people. And best of all, they can communicate in multiple languages, increasing the reach of your video and expanding your audience.

The world of animation also tends to stay much more accessible.

A modern AI video generator offers multiple animation options, allowing you to create animated characters and stories with your own music, narration and much more.

What once required an almost impossible investment from a professional or small business can now be achieved with an AI video generator.

With the right commands, you create personalized content, tailored to different audiences, languages ​​and contexts, and all of this with increasingly impressive quality.

With this overview in mind, let’s take a look at three solutions that are at the forefront of this revolution: Hailuo, Kling, and Google’s Veo 2 and Veo 3 models.

AI Video Generator: 3 Options for Your Business

Our team tested three software programs that have been successful among content creators with artificial intelligence.

Each AI video generator has been tested for its informative video creation and animation development capabilities.

There were days of testing, and below we present our conclusions about each one.

Hailuo: Simplicity in Creation

Hailuo is an AI video generator that works very well for creating animations, being one of the best for scenes with more than one character moving. Although we think Kling has better fluidity.

One of its great advantages is not having the negative prompt option (as in the case of Kling, see image below), which is great for those who don’t want to have to create more complex prompts.

To create informative videos, simply enter text. The AI ​​interprets the content, suggests images, and attempts to generate appropriate animations (this part still has a lot of errors, with the same prompt potentially generating different animations).

The result is a clear and educational video that can be used both in course introductions and in more technical explanations.

However, Hailuo doesn’t have an audio generator; you’ll need to use other software to produce the desired audio and then combine it with the generated image.

A big advantage of this AI video generator is the availability of an Unlimited plan, which saves you from having to keep buying credits.

Key points:

• Smoothness of generated images and animations
• Unlimited Plan

Kling: When Learning Gains Movement

One of our favorites, Kling focuses on animated videos (motion graphics) with expressive characters and engaging visuals.

This tool allows you to create real stories with animated characters that gesture (although they are not very good with hand movements), interact with the content and keep the viewer engaged.

For online teaching, this is especially valuable. Many students retain content better when it’s presented visually and with storytelling.

With Kling, you can create a character that takes on the role of instructor and guides the student through a visual journey. 

This character can interact with elements like flowcharts, animated code blocks, and graphs, making the content more accessible and fun at the same time.

It has great image generation features, just insert the command and desired reference.

However, don’t expect to enter a prompt and leave with your video ready. Each prompt generates a scene of up to approximately 10 seconds, and you’ll need editing software to put it all together into a single story.

The same goes for the audio part, as an AI video generator will rarely have audio and sound production capabilities, requiring support from other software.

Google Veo 2 and Veo 3: Studio Quality 

If Hailuo and Kling bring quick and affordable solutions, Google Veo 2 and Veo 3 take audiovisual creation to an even more advanced level.

These solutions are designed to offer post-production resources and multimodal generation of quality videos.

Veo 2, for example, is ideal for those who already have recorded videos — perhaps a class captured with a cell phone or simple camera — and want to raise their level.

The best of all for animations in terms of fluidity and more complex movements, but with more difficulty in interpreting prompts as expected.

Veo 3 is the current top-of-the-line. It lets you create videos up to eight seconds long from text and still images.

These tools are particularly useful in longer or more technical courses, where visual clarity and aesthetics can make all the difference in student retention. But the price is also higher.

Key points:

Google Veo 2

• It’s possible to generate videos from text-only prompts.
• It’s possible to create videos from text prompts and define which reference image/scene should start and which should end.
• It’s possible to generate more than one video at a time.

Google Veo 3

• It allows you to create scenes based solely on prompts, but videos can include the character speaking and even ambient sound if the prompts are well-written (which makes them easier to interpret).
• Improved fluidity in movements, especially hand movements.

Cost of Prompts for Video Generation

Every AI video generator requires you to use prompts (commands), which are nothing more than text inputs explaining what you want it to do.

For example: Create a lion with glasses giving a math lesson in front of a blackboard.

From this command, with the support (or not) of reference images that you give, the software will create what was requested.

Although, each prompt has a cost, which can vary easily between cents and several dollars. See the estimate below.

When you subscribe to any of the programs we list, you earn X number of credits and if you use more than the amount stipulated in the plan, you have to pay more.

That’s why we said Hailuo has an advantage, as it has an unlimited plan option (at least that’s what it claims).

Practical Applications in Online Education

We use all 3 software to create animation, because yes, it is perfectly possible to use the three solutions in an integrated manner to achieve better results. After all, each one has strengths and weaknesses.

You can do the same to create online courses. For example, for course presentations, Hailuo can generate a video to welcome the students and a brief explanation of what lies ahead.

Afterwards, during the theoretical modules, Kling can come into play to illustrate abstract concepts through animations and characters.

In the more technical or practical modules, where you willIf you already have videos recorded (such as demonstrations, practical classes, or interviews), Google Veo 2 can refine the material, making it more professional.

And for promotional content, course trailers or reinforcement videos with a summary of what was seen, Veo 3 can create engaging clips with cinematic transitions and strong narrative.

Again, remember that none of the software offers editing options (yet). You’ll need to use other applications to combine the generated material into a longer video.

What to Consider When Using an AI Video Generator

While the benefits are many, it’s important to remember that using AI in video creation doesn’t eliminate the need for human curation.

Trust us when we say that no matter which AI video generator you choose, you’ll still have a lot of work to do until you get a result you’re happy with.

Before you begin, pay attention to this TIP from our master user: Research extensively on channels dedicated to tips on animation, scenes, filming angles, story, etc. Then search for channels specifically focused on AI creation. Only then should you start investing for real.

The Future of AI-Powered Video Production

We’re just at the beginning of this transformation. As AI evolves, we’ll likely see even more interactive videos that adapt in real time to student behavior.

It is also possible that teaching platforms directly integrate these tools, allowing the creation and constant updating of content based on feedback and performance metrics.

The future of education involves more dynamic, personalized, and accessible videos—and artificial intelligence is the bridge that’s making this possible.

Remember: AI is a partner — never a replacement — for the human creator. With a smart strategy, it can improve the quality of your course, engage more students, and deliver value in a more scalable way than ever before.

Tools like Hailuo, Kling, and the Google Veo 2 and Veo 3 models offer incredible possibilities for those who want to educate with quality, even without great technical resources.

If you’re an educator, content producer, or digital entrepreneur, these solutions are worth exploring.
