Not the same job
We've been asked this question many times: for product videos, should I use Veo 3.1 or Seedance?
There's no simple answer, because these two models aren't competing for the same job.
What Veo 3.1 actually is
Veo 3.1 is Google DeepMind's model released in October 2025. Its genuinely distinctive feature is native audio-visual co-generation — not "add audio to a video" but "generate both at the same time," which is why its dialogue lip sync and ambient sound realism are difficult for other models to match.
The trade-off is cost. As a third-party reference point, Google's public Gemini API list prices (as of March 2026 — verify before you budget) were about $0.15/second for the Fast version and $0.40/second for Standard, so an 8-second clip lists at roughly $1.20–$3.20. If your content depends on dialogue accuracy or audio quality, that cost is justified. If you just need a product demo without speech, Veo 3.1 is overkill.
Also: Veo 3.1 maxes out at 8 seconds per generation. Longer videos require multiple generations and manual editing.
Where Seedance fits
Seedance models are generally more cost-effective — 1.0 Pro is the cheapest, and even Seedance 2.0 costs less than Veo 3.1 Standard. More importantly, Seedance is better adapted to typical e-commerce needs: more aspect ratio options, more flexible duration control, and faster iteration cycles.
Seedance also has an edge on physics — 2.0's physics simulation outperformed Sora 2 and Kling 3.0 in our tests. If you need realistic liquid flow, objects landing, or material deformation, Seedance 2.0 is currently the more reliable choice.
A practical split
Based on our testing, here's how an e-commerce brand might divide its video work:
If budget is tight, master Seedance 1.5 Pro first — it covers around 80% of typical daily needs.
On Nano Banana specifically: the video workbench is in demo mode — results are placeholders and no credits are charged. The cost estimator already reads the site's pricing table (25–110 credits per 5-second clip depending on tier, double for 10 seconds), so the workflows above translate directly once real rendering lands.
- Daily product clips (Douyin/TikTok/Reels) → Seedance 1.0 Pro — lowest cost, fastest output
- Music-synchronized content → Seedance 1.5 Pro
- Brand story films or ads with dialogue → Veo 3.1
- Premium brand films or multi-shot narratives → Seedance 2.0 or Veo 3.1 (depending on whether there's dialogue)
