Within a few minutes, a hyperrealistic video was up on X (the former Twitter) showing Tom Cruise wrestling Brad Pitt over the last slice of pizza. It had perfect sound, shadows and facial expressions.
In just 72 hours it racked up 1.8 million views. Insane.
And Hollywood? It held its breath. Rhett Reese, the screenwriter behind the hit film Deadpool, summed it up on social media pretty bluntly: "I hate to say it. But for us, this is probably the end."
Ladies and gentlemen, allow me to introduce Seedance 2.0.
Right now the single most powerful AI video generator on the market, one that turned ordinary mortals into directors of Hollywood blockbusters overnight.
And you should sit up and take notice.
A quick summary for those who are pressed for time
- Seedance 2.0 is a new AI model from the owners of TikTok, the first to generate video and sound together.
- It understands up to 12 inputs at once (videos, photos, audio, text) and keeps a character's face consistent across shots.
- In independent tests it's currently crushing the competition, like OpenAI's Sora and Google's Veo.
- Hollywood studios are threatening lawsuits over copyright — Disney, Netflix and Paramount have already sent cease-and-desist letters.
- You can try it for free through the CapCut or Dreamina apps — just 2 minutes and you have your first video.
What Seedance 2.0 is and why the whole internet is talking about it
ByteDance (the folks who own TikTok) don't sleep. They built a monster. And I mean that in the best possible sense.
Until now, AI video worked like this: you generated silent moving images and then had to painstakingly glue the sound on in another program. Seedance 2.0 changes that.
As the very first in the world, it generates video and sound at the same time.
The magic is called a Multi-Modal Diffusion Transformer (I know, it sounds like a part for a spaceship). In practice it means the AI understands the context of image and sound as a single whole.
When a glass falls in the video, you hear the shattering right away, at the exact millisecond it hits the ground.
The model first saw the light of day in February 2026. The global rollout for everyone came at the end of March through the well-known apps CapCut and Dreamina. And the internet has been going wild ever since.
Incidentally, in the first week alone over 2 million users tried out Seedance 2.0 on Dreamina. That's faster adoption than ChatGPT had in its early days.
What Seedance 2.0 can actually do
This is long past being just a toy for making funny GIFs. The numbers speak for themselves.
- It chews through anything: You can feed it up to 12 files at once. Say 9 product photos, 3 sample videos, a music bed and a text prompt. The AI combines it all and spits out a flawless result.
- Consistent faces: This is a game changer. You tag a face photo with an @ handle (say @Jana) and the AI keeps her face exactly the same across every generated scene. No more shifting eyes and deformed noses.
- Perfect lip-sync: Characters speak fluently in more than 8 languages. And their mouth movements land precisely on the syllables.
- Cuts straight out of a film: Want to go from a wide shot to a close-up? No problem.
- Quality and speed: 2K resolution, clip lengths of 4 to 15 seconds, and the best part? Generation takes under 2 minutes.
Seriously. Under two minutes. Try making a coffee in that time.
TIP: Start with a simple prompt — say "a woman walks along a beach at sunset, with the sound of waves and wind." Once you see the result, you'll understand why Hollywood is shaking.
How Seedance 2.0 beat Sora, Veo and Runway
Who's the current king of AI video? The numbers don't lie.
In the Artificial Analysis ranking (the largest independent benchmark of AI models), Seedance 2.0 left everyone in the dust. It hit an Elo score of 1,269 in the text-to-video category (first place) and an incredible 1,351 in image-to-video.
How does it stack up against the rest of the pack?
- Seedance 2.0: The multimodal king. Sound and video in a single package.
- Sora 2: Still has the best world physics and can do clips up to 25 seconds, but it's slower and pricier.
- Google's Veo 3.1: Wins on pure 4K cinema quality, but it lacks native audio.
- Kling 3.0: The Chinese challenger competes on price (just $0.075 per second of video), but it loses to Seedance on character consistency.
Boom. ByteDance simply flexed its muscles.
Why Hollywood is sending cease-and-desist letters
When you build a tool that can generate a Star Wars scene better than the interns at George Lucas's studio, someone is bound to get angry.
Disney, Netflix, Paramount, Warner Bros. and Sony have already assembled a legal task force. The Motion Picture Association issued a statement condemning "massive copyright infringement on an unprecedented scale."
Politics is getting into the game too. US senators Blackburn and Welch are openly calling for the service to be shut down on US soil.
Why the panic? Because the model was clearly trained on millions of hours of copyrighted films.
ByteDance did hastily add a block on generating from photos of real celebrities' faces, but the genie is already out of the bottle.
As Rhett Reese put it: Hollywood has a huge problem.
How much Seedance 2.0 costs and how to try it
Here comes the biggest shock. While shooting a professional ad spot costs you hundreds of thousands of CZK (≈ tens of thousands of euros), Seedance 2.0 comes in cheaper than a month's worth of coffee at your favorite café.
How do you jump in?
- Through CapCut: An app that 800 million people have on their phones. Every day you get free credits to try it out.
- Through Dreamina: ByteDance's web interface. The free version doesn't even ask for a credit card.
- Paid membership: If you want to generate more, it costs you roughly 250 CZK per month (≈ €10).
- For developers (API): You pay about 3 CZK per second of generated video (≈ €0.12).
The free credits run out fast, though — and anyone who dawdles will have to wait for the next day. The sooner you start experimenting, the sooner you'll find out what works for your business.
TIP: If you're just starting out, download the desktop version of CapCut. It's far clearer, and the AI video tools light up right there on the home screen.
What it means for your marketing
Fine, Hollywood is crying. But what does it mean for your business?
It means professional video content is no longer the preserve of big brands with huge budgets. An AI video generator lets you create UGC ads (authentic content) or product videos at a fraction of the cost.
How can you put it to use as soon as tomorrow?
- Photograph your product against a white background.
- Upload the photo to Seedance 2.0.
- Write a prompt: "The camera orbits the product, a sunny beach in the background, summer music playing."
- Two minutes later you have a finished creative for a Facebook ad.
At LK Media we've been testing AI video tools for creating client creatives for a while now, and honestly the results are unreal. The conversions often beat conventionally shot videos — and at a tenth of the budget.
If you make content for Instagram Reels, Seedance will save you hours of work. All you need is a good script and, for instance, these 50 hooks for social media.
Don't wait for your competition to start doing it. This is exactly the moment when being one step ahead makes a huge difference.
Where Seedance 2.0 still has bugs
Just so we're not all praise. It isn't perfect. (Yet.)
When you ask the AI for a really fast action scene, the details start to fall apart. Fingers on hands mostly add up to five now, but during a run the legs occasionally turn into spaghetti.
Multiple people talking at once is also a problem. When you have two speaking characters in the shot, the AI sometimes doesn't know whose mouth to move.
Likewise, generating legible text directly into a video (say, a slogan on a T-shirt) is still a bit of a lottery. Sometimes it comes out perfectly, other times it produces gibberish.
And of course, the unresolved copyright questions hang in the air like a very dark cloud. Before you upload a competitor's logo or a celebrity's photo into Seedance 2.0, think hard about whether it's worth the potential legal trouble.
Conclusion
That Irish filmmaker from the start of the article is already shooting ads for global brands today. From the comfort of his couch.
Seedance 2.0 isn't just another tech gimmick. It's a tool that puts enormous power in the hands of ordinary people. Whether you're a marketer, an e-shop owner, or simply an enthusiast, you now hold the power of a small film studio in your hands.
Don't miss the train. Open CapCut or Dreamina and try generating your first video today. You'll be amazed.
FAQ
Is Seedance 2.0 free?
Yes, the basic version through the CapCut and Dreamina apps offers free daily credits. For commercial use without watermarks and a larger volume of videos you have to pay extra (roughly 250 CZK per month, ≈ €10).
How does Seedance 2.0 differ from Sora?
The main difference is sound. Seedance generates the video and the sound effects at the same time, whereas OpenAI's Sora produces primarily silent videos (albeit at greater length and with better physics).
Can I use Seedance 2.0 for commercial purposes?
In the paid version, yes, but watch out for copyright. Don't generate videos featuring well-known personalities or protected brands, and you'll avoid unnecessary trouble.
Is Seedance 2.0 available in Czech?
The interface of apps like CapCut is available in Czech. On top of that, the model understands Czech text prompts brilliantly and even manages fairly decent Czech lip-sync.
Will AI video generators replace film studios?
They won't replace them entirely, but they will fundamentally change how they operate. B-movie production, ad spots and stock videos are already feeling a huge drop in demand.
Is my data safe when I use a ByteDance product?
ByteDance is subject to Chinese legislation, so if data protection worries you, it's a legitimate question. For ordinary marketing use (generating product videos), however, you're not uploading any sensitive data. If you're dealing with internal company content, consider using the API on your own server.
