ByteDance Releases Seedance 2.5 4K with Native 10-Bit Color for Film Production

ByteDance's Volcano Engine unveiled Seedance 2.5 4K on October 23, targeting professional film and television production with natively rendered 4K resolution and enhanced color depth. The model generates 30-second videos at 3840×2160 resolution with 10-bit color support, offering smoother color gradations and greater dynamic range than standard 8-bit output—an advantage for post-production grading workflows that require significant color adjustment headroom without visible degradation.
