Sora 2 — physical realism
Sora 2 excels at believable physics and world consistency: accurate motion, object permanence across a shot, and complex scene dynamics. Best when the realism of movement is what sells the clip.
Sora 2 vs Veo 3.1
Sora 2 (OpenAI) and Veo 3.1 (Google DeepMind) are flagship text-to-video models with different priorities. Sora 2 emphasizes physical accuracy — believable motion, object permanence, and coherent world simulation — but outputs silent video. Veo 3.1 generates a synchronized native soundscape (ambient, effects, dialogue, music) alongside the picture. On PonPon both run in the same workspace, so the practical answer is often "use each where it's strongest."
Features
What you can do
Veo 3.1 — native audio
Veo 3.1 renders a full soundscape with the video — ambient noise, frame-synced sound effects, dialogue, and music — so the clip is finished without an audio post pass.
Run both side by side
Generate the same prompt with each model and compare on Canvas. No reason to pick blind — keep whichever take wins for the shot.
Same prompt, same workspace
Switch models from one dropdown in PonPon Video. No separate accounts, no separate billing — free daily credits cover both.
Built for creators
Whether you're a solo creator, an agency, or a brand — every model adapts to how you work.

FAQ
Questions & answers
Is Sora 2 or Veo 3.1 better?
Neither is universally better — they optimize for different things. Sora 2 leads on physical realism and world simulation but outputs silent video. Veo 3.1 generates a full native soundtrack. Pick by shot: realism-driven action → Sora 2; finished clips with sound → Veo 3.1.
Does Sora 2 have audio?
No. Sora 2 outputs silent video, so you add audio in post or use it for scenes you plan to score yourself. If you need built-in sound, Veo 3.1 generates ambient audio, effects, dialogue, and music with the picture.
Can I use both Sora 2 and Veo 3.1?
Yes. Both run in the same PonPon Video workspace from one model dropdown. Generate the same prompt with each, compare on Canvas, and keep the better result. Free daily credits cover both.
Which is better for ads?
Veo 3.1 usually, because ads need finished audio — voiceover, music, product sound — and it generates all of that in one pass. Use Sora 2 when the ad hinges on hyper-realistic motion and you'll score it separately. See AI video with audio.
