I Made a Website Where You Can Create AI Videos from Text — Here's How
Source: Dev.to
Hi everyone! I want to share a project I just launched. It’s called Seedance 2.0.
What Does It Do?
You type a sentence, and it makes a video for you. You can also upload a photo and turn it into a video. The cool part? It also generates audio — voice, sound effects, and background music — all at the same time.
Example: type “A penguin walking on the beach at sunset” and you get a real video of that, with ocean sounds included.
Why I Built This
ByteDance (the company behind TikTok) released an AI model called Seedance. It’s really good at making videos, but you need to use their API, which means writing code. Most people don’t know how to do that.
So I built a simple website where anyone can use the model—no coding needed. Just type and click.
What Can It Do?
- Text to Video — Type what you want to see
- Image to Video — Upload a photo, make it move
- Audio included — Dialogue, sound effects, ambient sounds
- Up to 1080p resolution
- 6 aspect ratios — 16:9, 9:16, 4:3, 3:4, 21:9, 1:1
- 4 – 12 seconds per video
- Same character across shots — The face and clothes stay the same
How I Built It
- Next.js — Frontend + backend
- Tailwind CSS — Design
- Stripe — Payments
- fal.ai + BytePlus API — Connect to the Seedance AI model
- Vercel — Hosting
- next‑intl — Site works in English and Chinese
How It Works (Simple Version)
- Type a prompt or upload an image
- Pick resolution and aspect ratio
- Click Generate
- Server sends the request to the Seedance AI
- AI makes the video (with audio)
- Download it – no watermark
That’s it. Pretty simple from the user side.
Pricing
I use a credit system. You buy credits, then spend them to make videos.
One‑time packs (credits never expire)
| Price | Credits | Approx. videos (720p) |
|---|---|---|
| $9.90 | 1,000 | ~10 |
| $39.90 | 5,000 | ~50 |
| $99.90 | 15,000 | ~150 |
Monthly plans
| Price / month | Credits |
|---|---|
| $9.90 | 1,000 |
| $29.90 | 3,000 |
| $79.90 | 10,000 |
Higher resolution and longer videos cost more credits. Using credits instead of “X videos per month” is more flexible and fair.
Hard Parts
- Cost control – AI video generation is expensive. I spent a lot of time calculating credit costs so I don’t lose money while keeping prices reasonable.
- Two languages – Supporting both English and Chinese required more work than expected.
What’s Coming Next
- Seedance 2.0 model with 2K resolution (coming soon)
- Longer videos
- Video to Video – Use a reference video to guide generation

The cheapest pack is $9.90 — enough for about 10 videos to see if you like it.
