Veo 3.1 vs Sora 2

This is not a question of which model wins. One of them is being switched off. What matters is where a Sora request lands next, and what has to change when it gets there.

Night market street food stall: a cook tosses noodles in a flaming wok, oil hisses and the flame roars, steam drifts under string lights, crowd chatter and a distant scooter horn in the background. Handheld medium shot slowly pushing in.

Veo 3.1 is the closer landing spot when…

The shot is short, cinematic and repeatable. Veo takes the text-to-video work Sora was doing and adds a seed, a resolution choice and native audio — the three things a Sora pipeline usually bolted on afterwards.

Send it to Seedance 2.5 instead when…

The clip runs past eight seconds, or a character or product has to stay recognisable across scenes. Veo caps at eight seconds and three reference images, so a twelve-second Sora clip becomes two Veo shots — or one Seedance take.

What has to change in the request

  1. Sora's 4 / 8 / 12 seconds does not map onto Veo's 4 / 6 / 8. A twelve-second clip becomes two shots, or moves to Seedance 2.5.
  2. Sora fixed the resolution. Veo exposes 720p, 1080p and 4K, and the choice moves your cost — set it deliberately rather than inheriting a default.
  3. Sora returned silent clips. Veo generates a native soundtrack, so turn it off where a voiceover stage already exists rather than paying for audio you discard.
