Side-by-side comparison

| Image-to-video | Yes | Yes |
| Strongest at | Cinematic + product text | Face consistency + speed |
| Faceless product ads | Strongest | Capable |
| Pricing model | Scales with duration (8s baseline) | Fixed per scene |
| 3-scene 24s ad (std) | 54 cr | 120 cr |

Choose Sora 2 if…
- You need the lowest cost per second of generated video
- Your scenes show products, text, or labels with no on-screen person
- You want cinematic motion with strong physical realism
- You only need 3-scene ads — Sora chains scenes for consistency once Scene 1 renders
Choose Veo 3.1 if…
- A recognizable face or AI Twin must appear across multiple scenes
- You want native audio rendered from your dialogue script
- You need 3 scenes rendering in parallel for faster wall-clock time
- Cost per scene matters less than face/voice consistency across the full ad
Frequently Asked Questions
Which is cheaper, Sora 2 or Veo 3.1?
Sora 2 is significantly cheaper. At standard quality, an 8-second scene costs 18 credits with Sora and 40 credits with Veo. For a typical 3-scene 24-second ad, that's 54 credits with Sora versus 120 credits with Veo — a 2.2× cost difference.
Which has better face consistency, Sora or Veo?
Veo 3.1 has the strongest face consistency. Its image-to-video pipeline accepts a reference photo on every scene, so the same person appears consistently across the entire ad. Sora 2 uses edit-chains where the look locks after Scene 1 — strong for short ads but less reliable across many scenes.
Does Sora 2 or Veo 3.1 render faster?
For wall-clock time on a 3-scene ad, Veo is typically faster because all 3 scenes render in parallel (about 3 minutes per scene at standard). Sora renders scenes one at a time via edit-chains, so a 3-scene ad takes roughly 3× the per-scene render time.
Should I use Sora 2 or Veo 3.1 for TikTok ads?
If your TikTok ad shows a product with text overlays and no on-screen creator, pick Sora 2 — accurate labels and the lowest cost per second. If it shows a creator or AI Twin face that needs to stay consistent across the hook, body, and CTA, pick Veo 3.1.
Can Sora 2 do text-to-video without an input image?
Yes. Sora 2 supports both text-to-video and image-to-video paths. Veo 3.1 is primarily image-to-video for face-consistent renders, though it can accept text prompts for the scene direction layered on top of the reference photo.
The Verdict
For product ads where cost per second matters and the scene is faceless, Sora 2 wins on math alone (~2.3 cr/s versus ~5.0 cr/s). For creator-led content where a face or AI Twin needs to carry through every scene, Veo 3.1's reference-photo pipeline is the stronger pick despite the higher cost. Most UGC Copilot users pick the engine per ad, not per account.
