Question 1

Is Seedance 2.0 any different from the old version?

Accepted Answer

Real differences. Seedance 2.0 Video Generator takes images, videos, and audio all at once - version 1.5 couldn't mix that many input types together. The new model handles video extensions better (smoother transitions between clips), reference copying is more accurate, and characters stay consistent across longer sequences. Physics simulation and motion handling are significantly more stable. Generation speed got faster too. If you used 1.5 and found it limiting, 2.0 fixes most of those issues.

Question 2

How do I tell Seedance what each file should do?

Accepted Answer

Upload your files to Seedance 2.0 and write a clear prompt describing what you want. The AI automatically understands how to use your images for visual style, videos for motion reference, and audio for soundtrack. Just describe your vision in natural language - no complex tagging needed.

Question 3

Can I make videos longer than 15 seconds or am I stuck with short clips?

Accepted Answer

Direct generation caps at 15 seconds. But here's the trick - make a 5-second base clip, then extend it. Add 5 more seconds, then another 10 if you want. The extension feature keeps everything consistent (same character, same lighting) and you can chain them to hit 30, 45, even 60 seconds. Just set your extension length to match how many new seconds you're adding.

Question 4

What if I don't upload audio? Does the video come out silent?

Accepted Answer

No, it auto-generates sound. Footsteps, environment noise, basic audio that matches the scene. If you upload your own audio file, SeaArt AI uses that instead and syncs the visuals to it. The auto-generated audio works fine for previews but might need replacement for professional projects. You can also export silent and add audio later in post if needed.

Question 5

I tried text-to-video tools before and they never get camera angles right. How's this one?

Accepted Answer

Upload a reference video with the camera move you want, and Seedance 2.0 copies it. Way more accurate than describing "slow tracking shot from left to right" in text. Obvious camera moves (zooms, pans, tracking) transfer well. Subtle stuff like handheld shake or focus pulls might not be perfect, but the general motion path copies over. Pair video references with text prompts to fill in the gaps.

Question 6

What's the difference between those two modes - First/Last Frame and Full Reference?

Accepted Answer

First/Last Frame is the simple mode. Upload one or two images to set start and end points, write a text prompt, done. Good for basic animations. Full Reference mode gives you more control - combine images, videos, and audio for complex video creation.
