Choose the right aspect ratio in Seedance 2.0 for social clips, ads, and cinematic workflows.

Ratio Selection by Use Case

  • 9:16: Shorts, Reels, TikTok
  • 16:9: YouTube and cinematic horizontal video
  • 1:1: product and feed creatives
  • 4:3 / 3:4: editorial and balanced framing

Practical Rule

Pick ratio first, then write camera motion. Composition behavior changes with framing.

Prompt Tip

Add framing context:

Close-up portrait in 9:16, centered composition, subtle handheld motion, warm tone, 5 seconds.

Common Mistake

Users often test prompts in 1:1 and later switch to 9:16 without prompt adjustment. Reframe subject and camera path when ratio changes.
