Seedance 2: Best Motion Quality and Flexibility

Seedance 2 is ByteDance's flagship video model and currently delivers some of the most natural, cinematic motion in AI video generation. Key advantages:

  • Superior motion quality — Characters and objects move with fluid, realistic physics. Walking, turning, gesturing, and interacting all look natural.
  • Reference video support — Upload a reference video to guide motion style or camera work. No other model in this comparison offers this.
  • Longest duration — Up to 15 seconds at both 480p and 720p, giving you more storytelling room.
  • Most aspect ratios — Six options including 21:9 ultrawide for cinematic content.
  • Fast variant available — Seedance 2 Fast offers ~30% lower cost for drafts and iteration.

Best for: social media content, product demos, marketing videos, creative storytelling, and any project where motion quality is the top priority.

Kling 2.6: Best for Audio-Video Content

Kling 2.6 from Kuaishou is the only model here with native audio generation. Key advantages:

  • Audio generation — Generates synchronized sound effects and dialogue alongside video. No separate audio tools needed.
  • 1080p resolution — The highest native resolution in this comparison.
  • Strong realism — Excels at photorealistic scenes with natural lighting and physics.

Best for: content that needs sound, talking-head videos, product videos with ambient audio, and projects where 1080p resolution matters.

Sora 2: Best Photorealistic Quality

Sora 2 is OpenAI's flagship video model, known for its photorealistic output. Key advantages:

  • Photorealistic quality — Produces highly realistic scenes with natural physics and lighting that can be difficult to distinguish from real footage.
  • 1080p resolution — High-resolution output suitable for professional use.
  • Strong prompt following — Inherits GPT's language understanding for precise scene description.

Best for: realistic scenes, cinematic shorts, professional video content, and projects where photorealism is the primary goal.

Which Model Should You Choose?

  • Choose Seedance 2 if you want the best motion quality, reference video support, flexible durations, and the widest range of aspect ratios.
  • Choose Kling 2.6 if you need native audio generation or require 1080p resolution with synchronized sound.
  • Choose Sora 2 if photorealism is your top priority and you need 1080p output.

Pro Tip: Use Multiple Models

The smartest approach is to match the model to the task. Use Seedance 2 for motion-heavy creative content, Kling 2.6 when you need audio, and Sora 2 for maximum photorealism. Nano Banana makes it easy to switch between all three in one workspace.
