Overview
Seedance 2.5 is a new-generation video generation model disclosed by ByteDance Volcano Engine at the FORCE conference on June 23, 2026, and fully opened to the public in July 2026. Its biggest highlight is the first-ever single-shot generation of a complete 30-second video—completely eliminating the pain point of "5-10 second splicing → character drift" in AI videos, bringing AI video into the industrialization stage of long-form video.
Three core upgrades: (1) Single generation of a 30-second video without segment splicing; (2) Reference material limit increased from 12 to 50—supports simultaneous import of images/storyboards/audio-video/character settings, crucial for script-level creation scenarios; (3) New 3D white-box preview + built-in fine editing, supporting local subject replacement.
Commercial data is the most explosive in the field: Seedance 2.0 monthly revenue stably exceeds 1 billion RMB, annualized ARR of 14.3 billion RMB, gross margin of 70%—the highest global revenue in the AI video track from 2025-2026, far surpassing competitors like Runway and Pika. Internal testing is only open to film/tourism/brand enterprises, individual creators cannot apply yet.
On 2026/9/29, SkyProduction launched the Seedance 2.5 draft mode, which generates a 480P preview before committing to the 1080P final render; Volcano Engine testing measured about 57% cost reduction in typical scenarios and up to 90% in high-iteration workflows.

Pricing
Internal testing: Currently open to film, tourism, and brand enterprises; individual creators can apply through the Volcano Engine official website channel. Official release is expected in early July, with pricing based on a combination of video duration, resolution, and collaboration seats. Specific package details will be announced on the Volcano Engine official website. The draft mode launched on 2026/9/29 generates a 480P preview before committing to the 1080P final render; Volcano Engine testing measured about 57% cost reduction in typical scenarios and up to 90% in high-iteration workflows.
Summary
Seedance 2.5 is a landmark product in the 2026 AI video track that turns the page on the "short video splicing" era—30-second single-shot + 50 references + 3D white-box + built-in editing + ARR 14.3 billion make it nearly unrivaled in B-end scenarios like film/tourism/brand. The 2026/9/29 draft mode adds a 480P preview step before the 1080P final render, measured at about 57% cost reduction in typical scenarios and up to 90% in high-iteration workflows. If you create long-narrative video content (ads/TVC/short dramas), Seedance 2.5 is a must-try; if you create social media short videos (15-second level), you can still use Kling 3.0/Veo 3/Hailuo AI; if you pursue the highest lens quality, you can combine Runway Gen-4/Sora 2 for key shots.
