Four rules for choosing the right Seedance model
Rule 1 — Test & preview on Seedance 2.0 Fast 480p ($0.25 / 5s)
At 48,600 tokens per 5s clip, 2.0 Fast 480p verifies lighting, product framing, and camera movement at one-fourth the cost of 2.5 720p.
Rule 2 — Use Seedance 2.0 Fast 720p for 90% of 9:16 social product ads
2.0 Fast is 49% cheaper than Seedance 2.5 ($0.56 vs $1.06 on Ark; $1.21 vs $2.37 on fal.ai) and ~20% cheaper than 2.0 Standard, while delivering crisp 720p vertical feeds.
Rule 3 — Reserve Seedance 2.5 for 15–30s narratives or 16–50 reference assets
Only pay the 2.5 premium when your script requires clips longer than 15 seconds, standalone audio driving, or more than 15 reference files.
Rule 4 — Switch to Seedance 2.0 Standard whenever you need true 1080p
Seedance 2.5 does not offer native 1080p on Volcengine Ark, BytePlus, or fal.ai. For native 1080p output, always select Seedance 2.0 Standard.
