WHAT

What is Seedance?

Seedance is a video generation AI from ByteDance. From a single request it produces a continuous 30-second scene with sound, and it is widely rated as the most polished of the tools available today.

  • 1Output quality is far ahead of other tools
  • 2A single request returns a connected 30-second scene
  • 3Costs climb quickly once you start making several videos

WHY

What sets it apart

These are the differences we found by running the same material through several tools in our training sessions.

🏆

The results speak for themselves

Run the same prompt through several tools and the difference shows right away. Movement, lighting, and texture come out closest to footage shot by hand, so when we show it in a training session, the first reaction is usually 'This was made with AI?' Use it where polish builds trust, such as product intro shots and lecture inserts.

🧩

Give it plenty of reference material

Feed it product photos, space photos, and model shots, and it builds scenes that keep their look. Per the official announcement it accepts up to 50 reference inputs, which helps most in promo videos where the same product and the same person must repeat across many shots.

✂️

Fix only what needs fixing

It lets you select only the parts you dislike and redraw them, leaving the rest of the frame untouched. Instead of burning credits regenerating the whole video, you fix just one spot, which keeps costs down when a project goes through two or three rounds of revisions.

⚖️ The weaknesses are clear, too

It’s expensive. Pricing is per second of video, so regenerating short clips again and again drives the cost up fast. Once you connect it through MCP and automate it, you can top KRW 100,000 (≈ US$75) after just a few videos. Set a spending cap for each project before you start.

💡 In plain English

It is like a rookie director who walks onto the set once and shoots everything in a single take. The story flows without being chopped into lots of cuts.

🏢 Why it matters for organizations

Promo and training videos usually go to outside vendors. If you can produce a 30-second draft in-house, you can show a vendor the look you want instead of describing it. Meetings get shorter.

SCENE

Same job, different approach

You need a product intro video next week, but you have no budget

The old way

  1. Look for similar scenes on free stock video sites
  2. Live with scenes that show another company’s product instead of ours
  3. Cover the gaps with captions and music
  4. You end up saying, 'Let’s just use photos again this time.'

With Seedance

  1. Add a few product photos as references and describe the scene
  2. Generate one 30-second shot and show it to the team
  3. Select only the awkward part and redraw just that
  4. Finish by adding captions and music in an editing tool
USE

Common uses

01

Opening shot for a product intro

Use a product photo as the reference and specify the motion, such as 'camera slowly circling on a desk,' to create the opening shot. Add the detailed explanation afterward as captions.

02

Event and workshop openings

Create a 15–30 second mood video to play before an internal event starts. Add any text in an editing tool rather than generating it inside the video.

03

Training video inserts

Make scenario clips (work sites, customer consultations, etc.) to drop into a session. This is especially useful for safety and service training, where filming at a real workplace is difficult.

FIT

Who it’s for

Best for

  • ✓Teams that want to preview promo videos for a product or service in-house first
  • ✓Anyone making videos that need one long, continuous shot
  • ✓Anyone working with content where the same product or person appears across multiple shots

Better served by other tools

  • –Enterprise purchasing managers who need a clear billing and contracting channel
  • –Anyone who needs accurate Korean subtitles or signage text inside the video
  • –You mainly spend your time cutting and splicing footage
SECURITY

Can we use it at work?

The questions that adoption leads and security teams ask first.

Is your input used for training?How ByteDance-affiliated services handle input data depends on the channel you use (Dreamina or the enterprise API). Until you have confirmed which terms apply, do not upload internal materials.
Enterprise and team plansFor business use, there are separate API channels such as BytePlus ModelArk. The contracting party differs from a personal subscription.
In every caseNever upload photos of employees or customers as reference images without their consent. The same applies to photos of unreleased products.

Note: Whether input data is used for training, and the conditions for transfer abroad, must be checked in each channel’s original terms. We recommend a legal review before adoption.

START

10-minute quick start

  1. 1

    Go to Dreamina, ByteDance’s official channel, and create an account. Do not confuse it with similarly named third-party sites.

  2. 2

    Use the free trial to make one short scene and see what the output looks like.

  3. 3

    Upload product or space photos as references, and specify camera movement and lighting in plain sentences.

  4. 4

    Regenerate only the parts you don’t like, then add subtitles and music in an editing tool such as CapCut.

PROMPT

Copy-and-paste prompts

Replace only the [bracketed] parts, then paste it in.

Product introduction opening shot
[Product name] on a bright office desk. The camera pans very slowly from left to right, showing the product. Morning sunlight through the window, soft shadows, blurred background. Product only, no people. 16:9, calm and premium mood.
Event opening mood shot
Opening video for a [Company Name] workshop. In an empty auditorium, the lights come on one by one, and from a view of neatly arranged chairs the camera slowly moves forward. Warm lighting, an atmosphere of anticipation. No text or captions. 16:9, 20 seconds.
Training scenario recreation
A worker on a manufacturing floor, wearing a hard hat and protective gear, walks up to a machine and checks the inspection sheet. Start from an over-the-shoulder view and slowly move onto the hands. Realistic lighting, no exaggerated effects. The face should not be identifiable. 16:9, 15 seconds.
Lock the product with a reference image
Keep the exact shape, color, and proportions of the attached [product photo]. Place this product on a café table under afternoon sunlight, with a blurred view outside the window, and show a hand picking up the product. Never change the product’s form. 9:16 vertical, 10 seconds.
30 seconds in a single continuous shot
A single continuous 30-second shot with no breaks. Starting at the [store entrance], the camera moves inside and passes the [display shelves], the [checkout counter], and the [seated customer], in that order. The camera only moves forward, with no cuts. Natural light, realistic like a real space.
RECIPE

Using it with other tools

Linking two or three tools changes your work more than any single tool does.

One draft video (1 hour)

1Use Claude to outline the scenes and script for a 30-second video first
2Add product photos to Seedance as references and generate the scene
3Finish by adding captions and music in CapCut

Create training video inserts

1Create two or three scenario re-enactment shots with Seedance
2Add Korean narration with Typecast
3Generate captions in Vrew and overlay them
CAUTION

Before you start

  • Before paying, confirm the site is ByteDance’s official channel. There are many third-party sites with similar names.
  • Don’t have the video render Korean text. Adding text in an editing tool is far more accurate.
  • Get consent first before uploading photos of employees or customers as references.
  • Passing off an AI-made video as real footage destroys trust. If you use it in an advertisement, check the disclosure requirements.

HONEST

Where Seedance falls short

We don’t just list the positives. Here is what fell short when we used it.

  • Costs add up quickly

    With per-second pricing, regenerating until you like the result adds up fast. If you automate it through MCP, it’s common to top KRW 100,000 (≈ US$75) after just a few videos.

  • Faces drift as the clip goes on

    Long continuous generation is its strength, but toward the end a person’s look or a product’s details can drift subtly from the start. In practice, you end up generating short clips and stitching them together.

  • It’s awkward to expense through the company

    Personal subscriptions and business plans use different payment channels and contracting parties, so after paying with a company card you may have to explain what you actually bought.

FAQ

Per Dreamina’s official guidance, you get 4 free Seedance 2.5 generations for 3 days. That is only a taster, so business use requires payment. Pricing is per second of video, so shorter clips mean lower costs.
Describing scenes in Korean works. But drawing Korean signs or captions inside the video is still hard to expect. If you need text, add it in CapCut or Vrew.
It works well for drafts and internal review. Before using it, check the terms to confirm who the billing and contracting entity is and how uploaded materials are handled. As a rule, don’t upload photos of unreleased products or employees’ faces.
