Everything online is slowly but surely overtaken by algorithms and artificial intelligence.

Have you ever thought about how advertisements you see on YouTube and other places seamlessly adjust based on your online search history? 

That's the work of AI and algorithms!

And one of the most recent technologies that are becoming increasingly realistic is AI video generators!

In the future, you might watch a video online without knowing if it is a robot or a real human being. 

I'd argue that we are there already!

Let's explore what an AI video generator is and how they work today.

You might be shocked at what you'll discover.

What Is an AI video generator?

AI video generators are online software that primarily works in your browser and creates video content from scratch using artificial intelligence algorithms. 

The tools can create videos of any length and with any content based on a set of input parameters. It sounds very "sciency," but it's straightforward.

For example, a user can input a set of keywords, and the AI video generator will automatically interpret, understand, and create a relevant video to those keywords.

Or the more popular option is to script a few paragraphs of text or even take an entire blog post that you feed the AI. 

It will create a professional-looking video for you in minutes, with voiceover.

You can choose from various templates, styles, and actors to make your video look its best.

The AI video generator will even, in some cases, add music and sound effects to make your video more engaging.

What Types of Videos Can Be Generated Using AI?

The entire point of AI video generators is to make content creation faster and easier without having to show your face on camera.

And when it comes to AI video generators, you can create two main types (or styles) of videos.

One type is a simple video compilation of different images and videos. 

You either upload your video snippets or let the AI choose from a stock library of millions of professional videos. 

The AI will then create an entertaining and informative video, usually with subtitles and a voice according to the text you give.

A more exciting type of video that you can create is using human avatars. 

Human profiles with different shapes, sizes, skin colors, and mannerisms are essentially human presenters.

This process can be used to create a wide range of videos, including realistic videos, lip-synced videos, and even videos of people speaking different languages! 

The brands that create these avatars focus on making the lip sync spot on and include natural human facial expressions and movement to make these avatars through complex equipment.

With these two types of videos in mind, there are a few specific use cases that can be interesting for a business, such as:

  • Product explainer videos

  • Tutorial and how-to videos 

  • Promotional videos 

  • Brand videos 

  • Testimonial videos 

  • Customer testimonial videos 

  • Case study videos 

  • Webinar videos

  • Interview videos

How Does an AI Video Generator Work?

The simple answer is that you just give the software some background info or a specific copy/text that you want it to generate a video around, click a button, and voila, you have a video!

The more complex answer is that it takes input variables like text, images, or keywords and runs them through complex algorithms and neural networks trained with deep learning and machine learning algorithms. 

It then sifts through a lot of data and information and compiles a video that matches the criteria. 

The algorithms are fed hundreds of thousands of datasets with feedback loops to train the AI to produce accurate results.

Some AI video generators use a technique called 'generative adversarial networks (GANs).

GANs involve two neural networks working together: a generator and a discriminator. 

The generator creates new videos based on the given data, while the discriminator tries to spot the difference between real and fake videos. 

The more accurate the discriminator becomes, the better the generator creates realistic videos.

Whatever happens in the back-end doesn't matter to end users like you and me. 

You want the user experience to be easy and the results to be great; that's all that matters.

Why You Should Consider Using an AI Video Generator

There are a lot of reasons to consider using an AI video generator. 

Some of the benefits include: 

| Increased productivity

The AI video generator can help to increase productivity as it can automate the creation of videos. This can free up a ton of time for other tasks to be completed. 

| Improved quality

The AI video generator can create videos of a higher quality than someone terrible at English, has no video editing skills, or is nervous on camera. 

| Wider reach of a global audience

Most of these AI video generators have support for different languages. They can create videos in English, Spanish, Chinese, German, and more!

Overall, AI video generators help you save a ton of time and money; nowadays, they're effortless to use.

All you need to do is upload your text, video, or photos, and the AI software will take care of the rest. It's that simple!

AI video generators also offer a host of other benefits, including:

  • Customizable video templates

  • Fast and easy sharing through the cloud

  • No need for you to be on camera at all

  • Great for businesses looking to scale content marketing.

How to Use an AI Video Generator

It depends a little bit on the software and the type of videos it can create.

But basically, you start by uploading your videos and the text you want to include.

The AI video generator will then analyze the files and use its artificial intelligence algorithms to create a new video for you. 

You can then edit the video however you like, rearrange certain parts, adding subtitles, filters, and other effects.

The great thing about AI video generators is that they're usually easy to use

All you need is a basic understanding of how to use a computer, and you can create amazing videos with little to no effort. 

So, if you're looking for an easy way to create stunning videos, an AI video generator is a great tool to consider in your video marketing toolbox.

Tips for Using an AI Video Generator

One thing is always true when using AI in any field, such as AI writing tools and AI video generators.

The quality of the output is highly dependent on your input.

Meaning if you're lazy about holding the AI's hand and directing it with particular and relevant content, it will not be able to produce anything meaningful.

The machine is just as good as a master operating it.

So the best tip I have for you is to spend some time figuring out what you need to provide the AI for it to do its job correctly.

The sites that provide these AI video services always have some tips and tricks on using it the best, but it always comes back to having good inputs.

How to Choose the Right AI Video Generator

The first step is to determine what you want to use it for. 

Are you looking to create marketing videos, product demonstrations, or social media content? 

Maybe you want to edit videos faster with the help of nifty AI functions? 

Once you've narrowed it down, you can consider factors like price, features, and user-friendliness.

Thankfully, there are many great options; the best one for you depends on your budget and needs.

What Is The Quality of The Videos Generated by an AI?

You'll get high-quality video outputs if you sign up for a quality service or brand established in the space. 

Fortunately, most of these brands let you try the software with a free trial! 

How Long Does It Take To Generate a Video Using AI?

It takes minutes to generate videos. 

All you do is provide the AI with what it needs, usually just an article, text, or some paragraphs you want to discuss.

Choose your avatar, use a template, select some options and colors you like, and push a button

Now you often need to do this a few times and adjust certain things to get an output you're satisfied with. 

But compared to regular video editing, which can take HOURS of your time (literally 10 hours for a project) vs. 30 minutes tops with an AI video generator. 

It's a huge time saver if you find the right tool for the job.

How Much Does an AI Video Generator Cost?

The cost of an AI video generator can vary depending on the quality, features, and length of videos you want to publish. 

For example, a primary AI video generator that only creates simple videos may cost around $30 per month. 

However, suppose you want a more sophisticated AI video generator to create realistic, high-quality videos. 

In that case, the cost can be much higher, depending on the number of videos you want to generate in minutes.

Is an AI video Generator Easy to Use?

Yes, an AI video generator is very easy to use. 

You simply need to input text, keywords, or videos, and the AI will generate a new video based on your content.

What Are The Limitations of an AI Video Generator?

There are several limitations to an AI video generator. 

One such limitation is that the AI may not be able to generate a video that is realistic enough to be believable. 

This can be due to several factors, such as the AI's inability to accurately recreate human facial expressions or body language. 

Another limitation is that the AI may not be able to generate a video that is entertaining enough to hold someone's attention for more than a few seconds.

How Can I Create Videos With an AI Video Generator?

You can create videos with an AI video generator in a few different ways. 

The first way is to use video editing software with built-in AI video functionality. 

This software will allow you to create videos by inputting a script or storyboard, and then the software will generate the video for you. 

Another way to create videos with an AI video generator is to use an online video platform that offers an AI video generator with human-like avatars.

Wrap Up

An online video platform offering an AI video generator can benefit businesses to a great extent.

The human-like avatars can help businesses create videos faster and for various purposes. 

Just remember that no AI software is perfect. You may need to edit to ensure that your video is high quality and error-free. 

However, AI can be a great time-saver and can help you to create videos that are both creative and professional.
