Methodology
Thirty prompts across six categories — dialogue, product loops, cinematic B-roll, human motion, VFX and abstract. Same prompt string, default settings, one seed per model. No cherry-picking, best-of-one.
Dialogue and lipsync
Sora 2 wins outright. Veo 3.1 can lipsync but drifts on multi-word lines. Sora 2 also produces credible room tone. Score: 8/10 usable clips vs Veo's 4/10.
Product loops
Veo 3.1 wins on control — 'orbit clockwise, glass reflection stable' is followed literally. Sora 2 improvises. For ecommerce and packaging shots, Veo is the professional pick.
Human motion
Neither wins. Both trailed Kling 2.5 in our test. Sora 2 was slightly more realistic in isolation, Veo 3.1 slightly more controllable. If your shot involves dance, sports or nuanced gesture, run Kling first and reach for these as backup.
Cinematic B-roll
Sora 2 has the more instantly-cinematic default look — richer highlights, film grain, atmosphere. Veo 3.1 is cleaner and easier to grade. Preference call, not a knockout.
Verdict
There is no winner. Sora 2 for dialogue and atmosphere. Veo 3.1 for control and product. Both belong in a serious 2026 stack — using either one exclusively is leaving quality on the table.
- Dialogue → Sora 2
- Product & controlled shots → Veo 3.1
- Cinematic atmosphere → Sora 2 (slight edge)
- Human motion → Kling 2.5 (both trail)
- Cost per keeper → roughly equal at 2026 prices
