How is Seedance 2.0 different from other AI video generators like Runway or Sora?

Seedance 2.0 by ByteDance differs from Runway and OpenAI's Sora mainly in where and how you use it. Runway and Sora each sit in their own app with their own plans. Seedance 2.0 on PicX Studio is priced per second of video — from 45 credits/second at 480p — on the same credit balance as Kling 3.0, Seedance 2.5 and every image model, with plans from $11.99/month. ByteDance's motion synthesis technology produces fluid, cinematic movement particularly well-suited for short-form content, product videos, and social media clips — without platform lock-in.
