💡 Pro Tips for Better Results

Be Specific with Descriptions
Instead of "a person walking," try: "young woman in white dress walking through a garden at golden hour, gentle breeze moving her hair, shallow depth of field"

Use First & Last Frame for Transitions
Upload a starting pose and ending pose as first and last frames. Seedance 2.0 generates smooth, natural motion between them - great for product reveals, character animations, and scene transitions.

Master the @Reference Syntax
In Reference to Video, name your uploads and reference them directly in your prompt using @Image1, @Image2, @Video1, @Audio1. This precise syntax gives the model clear signals about which assets to draw from and how.

Upload More Reference Images for Consistency
Upload up to 9 reference images showing your character or subject from different angles. The more references you provide, the more consistent the character appears across generated videos.

Extend Instead of Regenerate
When a generated video needs a longer ending or trails off too soon, use Video Extend to continue it naturally rather than starting from scratch. Pair with a reference image to steer the extended direction.

Edit Instead of Regenerate
When a generated video is close but not perfect, use Edit Video to make targeted changes rather than starting over. Describe the specific edit you want in plain language.

Let AI Handle Audio
Toggle Generate Audio on when you want Seedance 2.0 to compose fitting background sound or ambient audio for your video automatically. Upload your own audio reference file when you want more control over tone and style.

Match Duration to Content
4-6 seconds for social media hooks and looping content. 6-10 seconds for product showcases and short narratives. 10-15 seconds for detailed scenes and cinematic sequences.

Choose the Right Aspect Ratio
16:9 for YouTube and presentations. 9:16 for TikTok, Reels, and Shorts. 1:1 for Instagram feed. 21:9 for cinematic ultrawide content. 4:3 or 3:4 for creative compositions.

Use Fast Mode to Iterate, Standard Mode to Finalize
Prototype your concept in Fast mode to check framing, motion, and timing. Once the direction is right, switch to Standard mode for the final high-quality render.
