Frequently asked questions
What is Seedance 2's max clip length in Teamday?
Teamday currently requests clips from 4 to 15 seconds per generation.
Does Seedance 2 generate audio?
Yes — and on BytePlus ModelArk audio does not change the price. In Teamday native audio is off by default so voiceover and music can be mixed in the assembly step, but it can be requested for a clip.
Does Seedance 2 support image-to-video?
Yes — Teamday passes an optional first frame (and optional last frame) so an approved still from Iris can anchor the clip.
How much does Seedance 2 cost per clip?
BytePlus ModelArk bills tokens (width x height x fps x seconds / 1024); for a 16:9 clip that works out to about $0.15 per second at 720p, $0.07 at 480p, and $0.37 at 1080p, with Seedance 2.0 Fast about $0.12 per second at 720p. FAL charges roughly twice that (~$0.30/sec) and Replicate $0.18/sec. Teamday's static estimate is $0.10 for clips up to 5 seconds and $0.20 above.
