ByteDance Opens Seedance 2.5 API With Single-Pass 30-Second Video, Studio Copyright Disputes Still Unresolved
ByteDance opened public API access to Seedance 2.5 through its BytePlus international cloud platform on July 16, 2026, completing a rollout first announced June 23 at the Volcano Engine FORCE conference
Seedance 2.5 generates a full 30-second video in a single continuous API call with no stitching, something no other commercially available model could do before this launch
Competing models require workarounds: Google Veo generates 8 seconds per native pass, Runway Gen-4.5 generates 5 to 10 seconds, and OpenAI's Sora went offline April 26, 2026 after being discontinued
Every major Hollywood studio has an unresolved cease-and-desist letter on file with ByteDance's general counsel over Seedance, with none of the disputes settled in court
A prior TechTimes investigation found Hollywood studio employees already use Seedance without formal approval, sending proprietary scripts and footage through a ByteDance API reachable under China's National Intelligence Law
