Seedance 2.0 FAQ: quick answers
Quick answers to the questions students ask most often. Every answer is covered in depth in the lessons — links included.
What is Seedance 2.0?
Seedance 2.0 is a multimodal video-generation model by ByteDance, running on the BytePlus ModelArk platform. It turns text, images, video and audio references into finished video clips with motion, light and camera work. Full overview in lesson 1.
How long can a Seedance 2.0 clip be?
A single clip runs roughly 4 to 15 seconds. For longer stories you chain shots inside one prompt — that is the multi-shot technique from lesson 9.
What resolutions does Seedance 2.0 support?
480p, 720p and 1080p natively, and the model can deliver up to 4K when the prompt explicitly asks for texture and face detail. Resolution strategy is covered in lesson 4.
Which aspect ratios are available?
16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and adaptive/auto — pick the frame shape for the platform you publish on.
What is the difference between Seedance 2.0 and 2.0 Fast?
Seedance 2.0 gives maximum quality: best detail, more stable motion physics and character identity. 2.0 Fast is quicker and cheaper with slightly lower quality — ideal for drafts. The working rule from lesson 11: test cheap on Fast, finalize expensive on 2.0.
How do I reference uploaded files in a prompt?
Use the universal syntax [Image 1], [Image 2], [Video 1], [Audio 1] — numbered in upload order. You can combine up to 9 images, 3 videos and 3 audio files in one generation. Details in lesson 7.
How do I keep the same character across clips?
Lock the identity with reference images plus a fixed word-for-word descriptor block in every prompt of the series, and reuse the seed. The full working scenario is in lesson 8.
What does the seed parameter do?
Seed controls randomness: the same prompt with the same seed gives a repeatable result, a new seed gives a new variation. Fix the seed, then change one thing per run — that is the iteration cycle from lesson 11.
Can Seedance 2.0 edit an existing video?
Yes. In video-to-video (V2V) mode you feed in a finished video and describe the change — costume, background, weather, style — and the model re-renders the scene. Examples in lesson 10.
How do I make the result look photorealistic?
Add the negation trick no 3D, no cartoon, no VFX to the style block and ask for skin texture, film grain and natural light. The full realism recipe is in lesson 10.
Where can I try Seedance 2.0?
Seedance 2.0 is available in ZenCreator's Image-to-Video tool. Your first generation takes one short prompt — the step-by-step walkthrough is in lesson 3.
