5 Best AI Video Generators in 2025 (Most Realistic Tools Yet!)

Hey everyone, Kevin here. Today we're going to 
look at the five best AI video generators. These   tools let you turn simple text into stunning 
visuals, and many of these are free to try. So,   you could follow along. I partnered with Zapier 
on this video, so let's check these out. First up,   we have Synthesia. This is a powerful AI video 
generator that lets you create videos using   realistic AI avatars and voiceovers in over 140 
different languages. Synthesia offers a free plan   so you can test it out. You get three minutes of 
video generation per month. And I know that's not   very much; however, it is enough to get a feel 
for whether you want to shell out $18 per month   for the starter plan.

With free, you get nine AI 
avatars, and if you go with one of the paid plans,   you get lots more video generation and also many 
more different avatars to choose from. Once you   finish signing up, you'll land here in the main 
Synthesia workspace, and building an AI avatar   video is very similar to pulling together 
a PowerPoint presentation. Right up on top,   you can start a new video from a template or from 
scratch. You can also turn files and links into   a video. You can dub a video or translate a video 
into another language, and over here, you can even   turn a PowerPoint presentation into a video. 
Let's test this out with just a blank canvas.   Let's click on this option.

Here, we see lots of 
different templates with AI avatars, and keep in   mind, we can customize all of these avatars, and 
we can also specify what the avatar should say.   Right up on top, let's go with this new one right 
here. Let's click on Use Template. This drops   us into the editor that you can use to build out 
your AI avatar video. Over on the left-hand side,   you can add additional scenes. This is kind of 
like PowerPoint, where you could add additional   slides to your presentation. Here, we see a few 
different examples. I'll click out of this. Over   here, we have the main scene. You can click within 
the scene, and you can edit any of these different   objects. For example, I could edit the text. 
Over here, I could select this shape. Up on top,   you can also add additional objects to your slide. 
For example, you can add another avatar. You can   add text, shapes, media, and you can even record 
your screen.

When you select any of the objects   in your scene, for example, I selected the AI 
avatar, over on the right-hand side, we have all   the different properties related to this avatar. 
Let's say that maybe I want to change out the   avatar. Here, I could click on Alex, and I could 
see all the different options. I'm on a free plan,   so I'm limited by what I can choose, but you get a 
feel for all the different options that are here.   For now, I'll stick with Alex. And here, we could 
adjust other properties as well. Now, down at the   bottom, I can also see the talk track that the 
avatar will say within this scene. So over here,   let's delete the text that's just placed here, 
and let me type in my own. Welcome to the Kevin   Cookie Company. I'll have Alex say this. Now, 
up on top, we can preview her saying this text,   or I could also generate it where it'll turn 
this into a video and she'll actually speak   this text.

Let's test that out. Once the video 
is all done generating, let's preview how it   turned out. Welcome to the Kevin Cookie Company, 
where we believe that every great day starts with   a cookie. We're thrilled to have you on board as 
part of our growing team. Let's now take this to   the next level by automating video creation using 
Synthesia. Zapier connects Synthesia to thousands   of apps. You can get started with Zapier for 
free at the link below. You can set it up so   when you get a new lead in an app like HubSpot, 
Zapier detects this and then triggers Synthesia   to generate a personalized video. Then Zapier can 
connect to your email and automatically send this   video to the lead. The lead gets a customized 
video from you without needing your involvement.  This isn't something that you could do with just 
HubSpot or just Synthesia. It's the connection   that Zapier makes between all of these 
different apps. With Zapier, you can   connect apps like Synthesia to Trello, ClickUp, 
Google Sheets, Monday.com, and thousands more,   even if the apps weren't designed to speak 
with one another.

Zapier lets you set up these   automations just by describing what you need. No 
coding needed. At number two, we have Sora. This   is OpenAI's video generation tool. You'll need 
a premium subscription starting at $20 per month   to be able to use it. Once you finish signing up, 
you'll land here in the main Sora interface. Sora   is a generative AI tool. What that means is it's 
generating new video based on all of its training   data.

Over on the left-hand side, we land in the 
featured view and here we can see all sorts of   different videos that other Sora users have pulled 
together. Over on the right-hand side, I see one   of a mouse with some interesting ears. If I'm 
curious about what type of prompt someone typed   in to get this video clip, here I could click on 
it. This opens up a larger view of that video and   down at the bottom, I can see the prompt. Maybe 
that serves as some inspiration. I'll close out   of this view. Back on the main screen, we have 
what's called the composer and this is where you   can describe the video that you would like Sora 
to make. I'll type in a description, a warm and   cozy Kevin Cookie Company shop filled with freshly 
baked cookies. Down below, we have a few different   options. Over here, you can upload an image if 
you'd like to incorporate that into the video.   You could also set the style of your video, the 
aspect ratio, the resolution, also the length of   the clip.

With the $20 per month plan, you can 
only generate up to 10 seconds and you need a   higher plan if you would like additional time. 
Over here, you could also select the number of   variations. I'll stick with two and then you also 
have a storyboard option if you would like more   control over what happens within the generated 
clip. For now, I'm good with just this prompt. So   over here, let's send that to Sora. And once it's 
all done, you can preview how the clips turned out   and look at all of that steam coming out of the 
cookies. You might want to wait a minute or two   before you take a bite. At the very bottom, you 
have a few different options. You could go back,   you could edit the prompt again. You could also 
recut it. Maybe you want to extend the clip. Here,   you could remix it if you want to change anything 
that appears within the clip.

For example,   maybe instead of having these jars, I want 
a different shape to show up. You could also   blend two different clips together and here you 
could set it up as a looping clip. Let's say you   really like one of these clips and you'd like 
to download it. Here, I could simply click on   the clip and right up on top, we have the option 
to download.

Third on our list is invideo AI V3.   This is a generative AI tool that creates full 
length videos rather than short clips like Sora.   invideo offers a variety of different plans 
and you can get started for free and you get a   generous 10 minutes per week of AI generation. So, 
what does that mean? You can type in a prompt for   the video that you would like to create, it'll 
write a script, generate voiceovers, and also find   matching stock media. However, it won't generate 
any new clips from scratch using AI. For that, you   need one of the premium plans. You have the plus 
plan and the max plan which give you 60 seconds of   generative credits. That's not very much, so 
if you're planning on creating lots of clips   from scratch using AI, you'll have to go with the 
generative plan which starts at $96 per month and   that gives you 15 minutes of generative credits. 
I'm now here in the main interface and we have   a text field where you can type in your prompts 
for the video that you would like to create.

Now,   the beautiful thing is you can type in anything 
that you've ever imagined and using generative   AI invideo will make it for you. So, it makes 
video creation accessible to anyone. Let's test   this out. Create a 30 second ad video for YouTube 
promoting the Kevin Cookie Company. Use a friendly   teddy bear as the mascot. Use wide cinematic 
shots and close-ups of chocolate chip cookies   from time to time. Let's see what it comes back 
with. On this next screen, we can choose whether   we want to use stock media or generative media. 
Again, with generative media, the AI is creating   the video clips from scratch. We have a few 
different settings here. I think all these look   good, so let's continue. It finished generating 
the video, let's now preview how it turned out.   In a world of rushing and noise, there’s a 
place where warmth awaits.

Meet our cuddly   bear who knows the best moments are shared. Hehe. 
With finest ingredients, and a dash of magic,   we bake cookies that bring people together, 
Kevin Cookie Company, where every bite tells   a story. Mmm. Visit KevinCookieCompany.com and 
taste the love today. That is very impressive. I   really liked how it turned out. Down below, we 
could also continue refining the video simply   by using natural language and the AI will make 
changes. So, let's test this out. Use epic rock   music as the background music and let's see if it 
can make that change. Let's have a quick listen.   I'll go back just a little bit and let's play it.
Mmm. Visit KevinCookieCompany.com and taste the   love today. It's subtle, but I like it.

Once 
you're ready to download, simply click on the   download icon. Here, you could select various 
settings. I'll go with 1080p and let's continue   and we now have a finalized video. At number four, 
we have Pika. An accessible and also fun AI video   tool that's free to try. Once you finish signing 
up for an account, you'll land here on the main   Pika interface. Similar to what we saw with 
Sora and some of the other video generators,   down at the very bottom, we have a text field 
where you can type in a prompt describing the   video that you would like to create. In the bottom 
right-hand corner, if you click on this icon,   Pika offers a few different models. With a free 
account, you can use the 1.5 model. With a paid   account, which starts at $8 per month, you get 
access to their more advanced models, which they   say have better motion and Pika scene support.

So, 
let's go with 1.5 with a free account to test it   out. Underneath the text field, Pika offers a few 
different modes. For example, we have something   called Pikaffect and when I click on that you can 
upload a video or photo and then you can apply   different effects to that video. For example, 
one of my favorites. You can generate a proposal   video. Try pulling that one on your girlfriend. 
That'd be a lot of fun. Over here, you have   something called Pikascenes. This is where you can 
upload a character an object or location and it'll   use that as part of your AI generated video. And 
lastly, there's also something called Pikaddition.   You can upload a video and a photo and it'll 
incorporate that photo into your video. Let's test   this one out because I think it's a lot of fun. 
Let me select a video and over here. I'll select   an image. Now that I've selected both a video and 
an image, let's combine them. Down below, let's   click on this icon.

And let's now play the video.
Not bad. Next up is Runway ML. They offer a   suite of AI video editing tools along with the 
generative AI video capabilities. Once you finish   signing in, you'll land in the main Runway ML 
interface, and if you've never heard of it before,   it's a creative AI platform that offers a variety 
of different tools that you can use to generate,   edit, and also enhance your multimedia 
projects all using machine learning. Let's   take a quick look at what some of those 
tools are. Over on the left-hand side,   let's click into all tools. Up on top, let's start 
by clicking into video tools and here we see all   the different video tools that leverage AI.

First 
up we have generative session. This is where you   could generate video from scratch. You could use 
AI to remove the background of a video. They have   something called frame interpolation. That's 
where you can fill in missing frames to make   it smoother. You could color grade. They even have 
in painting and the list goes on and on. Lots of   different tools that are well worth experimenting 
with. Let's close out of this and then click   into some of the image tools. You also have a 
variety of different image tools. For example,   if you want to expand the borders of an image, 
they have something called infinite image.

Here   you have something called expand image and the 
list goes on. Up on top, if we close out of this,   you also have a variety of different audio tools 
and at the very end, they also offer different   3D tools. The beautiful thing about Runway ML 
is you can experiment with AI in your projects   and you don't need extensive technical expertise.
Let's test out Runway’s generative session. I'll   click on this. First, we need to select an asset. 
I'll click on select asset and let's go with this   picture of a handsome guy. I’ll double click 
on that and now I see my picture. Down below   we can now describe the shot that we would like. 
I'll type in some text. This person works at a   cookie store and is serving fresh cookies 
to customers. Down below we have a variety   of different settings.

As an example, here you 
can control the camera. I'll leave it set to the   defaults. You can adjust the aspect ratio. Down 
below, you can select the model and also how long   you want the clip to be. With Runway ML, you can 
only select up to 10 seconds. For now, I'll leave   it set to 5 and then let's click on generate. Over 
on the right-hand side, it's now generated our   video. Let's play back to see how it turned out. 
There's the picture input and here's the output.   Look at that. He looks a little bit like me. Not 
exactly, but pretty close, and it also has the   red shirt. It's a polo shirt, so it doesn't match 
my shirt, but that's pretty close.

I like that.  Right over here. We have a variety of different 
actions that you could take. For example,   if you want to upscale to 4k, you have that 
option and over on the right-hand side,   if you'd like to download the video clip, simply 
click here and that'll download the clip to your   computer. And that's it. Five of the best AI 
video generators available today. Big thanks   to Zapier for sponsoring today's video. If
