Choose Seedance 2.0 when

- Native synchronized audio matters and you do not want a separate sound pass.
- You deliver in unusual aspect ratios (vertical, square, ultrawide) without cropping.
The bottom line
Think of Seedance 2.0 as the directed shot and Sora 2 as the long take. When the brief specifies exactly how a shot starts and ends, Seedance's controls pay for themselves. When the brief is a scene description and the win is believable motion over many seconds, Sora 2 is the better tool. Per-second pricing on both means cost scales with ambition either way; the live ranges are shown below.
