How to Use Seedance 2 for Text-to-Video: A Beginner’s Walkthrough

Seedance 2 is ByteDance’s text-to-video model that generates short 1080p clips from written prompts. You open the web app, type a scene description, pick an aspect ratio, and hit generate. First run takes about 90 seconds.

The catch is that most people write prompts like search queries, then blame the model when the result looks flat. This walkthrough covers the signup, the prompt shape that works, and the export settings you will actually want.

What is Seedance 2?

Seedance 2 is a text-to-video and image-to-video model from ByteDance’s Seed team. It outputs clips between 5 and 12 seconds at up to 1080p, and it can animate a still image you upload as the first frame. There is a free tier with a small monthly credit pool, and paid plans start around $10/month for heavier use.

It is not a full editing suite. No timeline, no audio layering, no multi-shot stitching. You generate a clip, download it, and assemble everything elsewhere.

How do you get started?

Sign in with an email or ByteDance account, then land on the generation screen. The interface has three inputs: a prompt box, an aspect ratio selector (16:9, 9:16, 1:1), and a duration slider.

1. Claim the free credits. New accounts get a starter balance, enough for roughly 6 to 10 short clips.
2. Pick your aspect ratio before writing. A vertical 9:16 prompt reads differently than a wide 16:9 one.
3. Set duration to 5 seconds for your first test. Cheaper, faster, and easier to judge.
4. Generate and wait. Queue times sit between 60 and 120 seconds on the standard tier.

How should you write the prompt?

Seedance 2 responds best to a described shot, not a list of keywords. Give it a subject, an action, a camera move, and a lighting condition. Compare “cat” with “a ginger cat walking across a sunlit windowsill, slow dolly-in, warm afternoon light.” The second one gives the model something to animate.

Three things that reliably improve output:

• Mention one camera move only. Two competing moves usually produce mud.
• Name the light. “Neon reflections on wet asphalt” beats “night.”
• Keep it under 60 words. Longer prompts tend to dilute the subject.

Negative prompts are supported too. Add “no text, no watermark” if you keep seeing garbled lettering in the corners.

Is the free plan enough?

For testing, yes. For anything you plan to publish weekly, no. The free credits refresh slowly, and rerenders eat them fast. A 12-second 1080p clip costs noticeably more than a 5-second one, so budget your longer attempts.

Who should skip Seedance 2 entirely? Anyone needing clips longer than 12 seconds, or anyone who wants dialogue synced to mouth movement. For that, look at a dedicated talking-avatar tool instead.

How do you export and use the clip?

Every finished generation sits in your library as an MP4. Hit download and you get the file at the resolution you picked. There is no built-in upscaler, so if you need 4K you will need external software.

One practical note: generate two or three variations before you commit. Seedance 2 is not deterministic, and the same prompt can land very differently on the second try.

Quick Summary

• Seedance 2 makes 5 to 12 second 1080p clips from text or a first-frame image.
• Free tier gives a small credit pool; paid plans start around $10/month.
• Write a described shot with one camera move, not a keyword list.
• No audio, no timeline, no upscaling — it is a generator, not an editor.
• Best for short social clips; skip it if you need clips over 12 seconds.
