Seedance 2.0

Seedance 2.0 is ByteDance's latest and most capable AI video generation model, representing a generational quality leap over Seedance Pro. It earns its flagship status through: the longest duration of any premium model (up to 15 seconds), 7 aspect ratios including the unique "auto" option, audio generation, multi-resolution output (480p/720p/1080p/4K), and the most advanced image-to-video system with primary image, end image, and reference controls. At 480p starting at 21 credits/s, it is priced as a premium tool — but delivers accordingly.

The costs scale significantly by resolution. At 480p (21 credits/s): 4s = 84 credits, 8s = 168, 15s = 315. At 720p (43.5 credits/s): 4s = 174, 8s = 348, 15s = 652.5. At 1080p (97.5 credits/s): 4s = 390, 8s = 780, 15s = 1,462.5. The 4K tier is extremely premium at 223 credits/s. Most users generate at 480p or 720p. For budget-conscious premium work, Seedance 2.0 Fast offers similar quality at a lower cost for 480p and 720p.

When set to "auto," Seedance 2.0 analyzes your text prompt and intelligently selects the most appropriate aspect ratio. A prompt describing a wide landscape might generate 16:9, a portrait scene might select 9:16, and a balanced composition might choose 1:1. This is useful when: you are generating many videos and do not want to manually select ratios, your prompt naturally suggests a format, or you want the AI to make the compositional choice. For specific platform requirements, always set the ratio manually.

Both are flagship models with different strengths. Seedance 2.0: longer max (15s vs. 8s), more aspect ratios (7 vs. 2), resolution options (480p/720p/1080p/4K), auto aspect ratio, and richer image-to-video inputs. Veo 3.1: cleaner per-frame visual quality, better audio synchronization, and lower per-second cost (29 credits/s vs. 43.5+ at 720p). For short premium clips (under 8s) with audio, Veo 3.1 is often the better choice. For longer clips, format flexibility, and creative control, Seedance 2.0 wins.

Seedance 2.0 offers the most comprehensive image-to-video control: a primary image defines the starting visual, an end image defines the destination state, and reference-based generation allows style and motion guidance. This enables: smooth transitions between two states (day to night, closed to open), character animation with defined start and end poses, product reveal sequences, and precise creative control over how the video unfolds. No other model matches this level of image-to-video sophistication.

Seedance 2.0 Fast (15.5 credits/s at 480p, 35 credits/s at 720p) offers strong visual quality at a lower cost. It lacks 1080p and 4K support. For social media and web video, Fast is often hard to distinguish from the full model after platform compression. Use Full Seedance 2.0 for: 1080p or 4K output, maximum quality for premium distribution, and projects where the quality difference between Fast and Full is noticeable and matters.

Seedance 2.0 excels at: cinematic narrative sequences that benefit from 15-second duration, dramatic lighting and atmospheric content, action scenes with complex motion, character-focused video with multiple pose changes, product showcase videos with sophisticated camera movements, and ultra-wide 21:9 cinematic content. ByteDance's expertise in video (from TikTok) shows in the model's understanding of visual storytelling and dynamic composition.

Yes. All Morphed-generated content — including Seedance 2.0 videos with AI-generated audio — is fully commercially licensed for any use: advertising, social media, broadcast, streaming platforms, client work, and commercial distribution. The premium quality of Seedance 2.0 makes it suitable for commercial applications that demand high production value.
