How does the AI video maker work?

AI video makers use Artificial Intelligence (AI) to create videos by using data from a variety of sources, including text, images, and audio files. 

While human involvement is still necessary to provide some direction, AI video makers can create videos with little to no human input. And yes, this approach of producing videos saves huge money from hiring actors.

So how do they work? 

To make AI videos choose any tool such as Synthesia. Enter any text, choose an avatar, and generate it.

The best part? No video editing is required. You don’t even need to appear on your videos as most video generators offer a wide range of avatars (aka human presenters).

Here’s what the AI-based avatars look like;

You can add images, music, and much more to your videos.

1. InVideo.io

InVideo.io Bottom Line: Best overall Solution for Text to Video production. Invideo.io is suitable for producing all kinds of videos (social media, ads, YouTube ads, promos, etc) where human actors are not required and users only have scripts in the text form.

InVideo offers 50+ AI-powered themes to convert text-based content to videos easily. You can create all kinds of videos including video ads, promos, YouTube videos, intros, and more from their library of 6000+ customizable templates.

The biggest advantage of this AI video software is that it can also generate a video even if you don’t supply the script in the first place. Isn’t it a cool thing?

Here are some of the amazing features you’ll get with InVideo

  • 50+ AI-powered themes to choose from
  • Access to 6000+ templates
  • Provides iStock media and music library
  • Automated Text to Speech
  • Use filters and transitions to create great videos 
  • Offers powerful editing software to customize your videos
  • Watermark free videos

InVideo.io Text to AI Video Process & Example (Sharing My Experience):

To create videos, you need to pick any template or theme and enter any text. That’s it, you can easily turn that script into an amazing AI video. You can add media including music, text, images, and more.

With the help of InVideo.ai, I have created this quick video from the text supplied. It only took 2 minutes and the accuracy and efficiency of this ai text to video tool are just amazing. I haven’t encountered any problems.

The best thing about Invideo is their AI system understanding. 8 out of 10 times it produced the exact video I required based on my script. Just like any other AI tool, it requires human touch for final refinement. It also generates subtitles for my videos. 

Overall I can say, Invideo is capable of reducing about 75-80% of the total video production time. The video output is best when you supply your script, but still needs some improvement for automated script-based videos.

So this is how I proceeded…

1. Free SignupI started with InVideo by quickly signing up for free.

2. Activating the Text to Video Mode

Then InVideo ask you to choose a workflow (3 Options are available, and for the testing purpose here I picked up “Text to Video”)

text to video templates in invideo

3. Browsing the Templates

So just after entering into the Text-to-video workflow, I have seen plenty of amazing templates. Most of the templates supported both landscape and portrait modes.

I wanted to generate an AI video from our fitness project script and luckily I have found a template for this.

4. Inserting the Text based script

Upon selecting the template, you have to provide a text script that you’re looking to convert into a video. 

invideo text script
No need to worry if you don’t have a script ready. You can utilize the built-in ChatGPT script generator in Invideo.io.

5. Generating the AI Video

Based on the paragraph lengths, InVideo uses its smart AI algorithm and splits the text into different scenes. In case you don’t like the automated generated scenes, you can make manual adjustments easily.

Once I had done the basic adjustments, I was ready to render the video. The rendering process hardly took 2 minutes. The final video came with the watermark because of the free version. But it can be easily removed through upgrades…

Quick note: Upgrading to the premium InVideo version also has one MAJOR advantage – Auto resize for all social platforms

DeepBrain.io Text to AI Video Process & Example (Sharing My Experience):

DeepBrain.io creators believe that you can generate text-to-video in just 3 steps using their amazing AI video suite: Open up the Video editor, Choose a template, Insert/Generate a script and you will be 80% done. Editing is required to give a final touch.

I subscribed to their service. As soon as I logged in, I found the following options on their home dashboard:

  • Start with ChatGPT: That is for those who doesn’t have a script
  • URL to video: I found this feature useless
  • Solid Background
  • Default Template
  • Import PPT
  • Start with Template
deepbrain io dashboard

Obviously, I have chosen a template.

Most of the templates available here have 5-7 scenes that you can easily customize 100% – which is obviously a good point.

For illustration, I inserted my script into one of their Workout text-to-video templates.

picking up a text to video template in deepbrain tool

The moment I tapped on a “Create AI Video” button, I was transferred to their AI video editor. 

Personally, it took me around 5-10 minutes to explore all the options available in the editor. Changing models, editing scenes, adding voiceovers, incorporating custom assets, and adding a logo—everything was easy to go.

deepbrain io ai text to video editor interface

One thing I didn’t like is their slow rendering process, meaning it feels like having a good internet connection is necessary for rendering the output.

The final exported video was in full HD, and the rendering was done well. Speaking of human touch, the avatars provided by DeepBrain.io appear quite human-like, so your video doesn’t seem like it’s being presented by a bot. The voiceovers used sound completely natural.

Apart from using templates, I also experimented with a couple of avatars. Inside the Avatars tab, there are plenty to choose from. Once you select an avatar, you’ll be prompted to try out this model.

Upon proceeding, you can input a script into the script editor and instruct your avatar to present it for you in a video.

Starting with avatars is easy overall. However, if you want a catchy background and additional elements, starting with templates is a better option.

4. Lumen5 

Lumen5 Bottom Line: Best for Blog Post to Video

Lumen5 is an excellent online tool for creating AI videos. Over 800,000 people are using Lumen5 to create professional video content. It is usually preferred by social media marketers or bloggers because of the fast video production benefit and support of multiple aspect ratios.

The best part about it is that it’s really easy to use and you don’t need any special video editing skills. You can create videos from scratch, or create videos in minutes with the assistance of artificial intelligence. 

Some of the excellent features offered by Lumen5 text to video AI generator are;

  • Drag and drop video templates
  • Content library with millions of stock photos & videos
  • Create unlimited videos
  • Custom colors & styles
  • 1080p video resolution
  • Upload watermarks & fonts 
  • Upload your own videos & photos

Experience with Lumen5 Text to Video Process:

I really like Lumen5 upto the point where I get the desired templates for converting my blog posts into short videos. It has only 30 universal templates which support the aspect ratio of all popular platforms (Pinterest, Facebook, YouTube, etc).

So my advice is to check their templates list in the free version before opting for the paid plans.

The transition styles, callout styles, automated captions, and simpler user interface are the main reasons I was able to generate my video in just 5 minutes. Yes, my text-based blog post is ready to upload on Pinterest & social media platforms in video format in such a short span of time.

If you’re interested in having a look at Lumen5 AI video output, here you go. I created this amazing Pinterest video from my blog post text script.

The final takeaway for Lumen5 from my side is, Just sign up for the tool and if you feel you have enough templates, go for it. Either ignore it. Invideo.io offers more templates and you can totally consider it as well.

Here’s how it works;

  • Enter a script or text
  • Lumen5 will automatically find the perfect audio and visuals based on the script
  • Upload your logo, music, custom text, etc
  • Download and share the video

You can also choose a blog post to turn into an amazing video. Here’s a quick video tutorial showing how Lumen5 works;

Cons:

  • Sometimes it takes too long to render and export videos 
  • You cannot get 1080p resolution in Lumen5 starting plans

How much does it cost?

Lumen5 does offer a free plan but its limitation is the watermark. To remove the watermark, you have 4 plans to choose from. Lumen5 has plans for everyone including individual content creators as well as big agencies.

All plans offer the benefit of unlimited video export but 1080p render is only available in 3 plans which means the Basic plan is useless. Plus the majority of high end essential features such as custom templates, custom fonts, and translations can only be found in expensive plans.

    Great list. I quite enjoy Synthesia, although you are right about how some of the AI avatars are a little less than realistic looking.

    InVideo looks promising, looks like I’ll be doing a bit of comparison shopping.

    Thanks!
