Veo 3.1 vs Seedance: flat-rate clips or per-second control

Veo 3.1 and ByteDance's Seedance are priced on opposite principles, and that difference decides most of this comparison. Veo 3.1 charges per clip — 25 credits on Fast, 100 on Quality — with no duration selector. Seedance charges per second, so a short clip is genuinely cheap and a long one is genuinely expensive.

At 720p, Seedance 2 Mini costs about 3.3 credits per second. An 8-second clip is 27 credits; the same 8 seconds on Veo 3.1 Fast is 25. Seedance also reaches places Veo does not on VdoBloom: 4K output, 21:9 framing and 30-second single generations.

Veo's advantage is predictability and its reference-image workflow. If you are running dozens of variations at a fixed budget per shot, a flat 25 credits is easier to plan around than a per-second meter.

  • Seedance 2 Mini accepts any whole-second duration from 4 to 15 seconds; Veo 3.1 has no duration selector on VdoBloom.

How it works

  1. 1.Decide whether you are paying for length or for volume

    If you need many short clips at a predictable price, Veo 3.1 Fast's flat 25 credits is simple. If your clips vary in length, Seedance's per-second billing means you only pay for the seconds you keep.

  2. 2.Test the prompt on Seedance 2 Mini at 480p

    A 4-second test is 7 credits. That is the cheapest way to check whether the model understands your scene before committing to a premium render.

  3. 3.Pick the aspect ratio before the model

    If the shot has to be 21:9 or 4:3, Seedance 2 Mini can do it and Veo 3.1 cannot — Veo is limited to 16:9, 9:16 and Auto, and its 1080p HD download only works at 16:9.

  4. 4.Know what sound costs

    Seedance 2 Mini includes native audio at no surcharge, so the price shown is the price with sound. Veo 3.1 does not expose an audio toggle in the VdoBloom controls.

  5. 5.Escalate to Seedance 2 or 2.5 for the hero shot

    Switch the model to Seedance 2 for 4K or to Seedance 2.5 for a single 30-second take. Keep the prompt you validated so the only thing changing is the model tier.

Frequently asked questions

Is Seedance cheaper than Veo 3.1?

At most lengths, yes. Seedance 2 Mini is 8 credits for 5 seconds at 480p and 17 at 720p, against a flat 25 on Veo 3.1 Fast. At 480p every length up to the 15-second maximum (24 credits) costs less; at 720p Mini stays under 25 through 7 seconds (24) and runs 27-50 credits at 8-15 seconds. So the comparison is really about control, not just price.

Which one can generate a 30-second clip?

Seedance 2.5: 4 to 30 seconds in a single job, at 11.2 credits per second at 480p, 25.2 at 720p or 63.2 at 1080p. Veo 3.1 has no duration control on VdoBloom, and no other model in the roster generates longer than 30 seconds in one pass.

Does either model produce audio?

Both can. Seedance 2 Mini, like the rest of the Seedance 2 family, generates audio by default at no extra credit cost. Veo 3.1 does not expose an audio toggle in VdoBloom's controls.

Can I animate an existing photo with either?

Yes. Seedance 2 Mini appears on both the text-to-video and image-to-video tabs, so the same model handles either input. Veo 3.1 takes 1-3 images through first-and-last-frame mode (1-2 images) and reference-to-video (1-3 images, veo3_fast at 16:9 only).

Which Seedance variant should I start with?

Seedance 2 Mini if you want the cheapest test, with 480p or 720p and 4-15 second control — it costs about 1.6 credits per second at 480p. Seedance 2 if you need 4K, and Seedance 2.5 if you need up to 30 seconds.

Do I have to choose one and stick with it?

No. Veo 3.1 and every Seedance variant draw on the same credit balance inside VdoBloom, which carries 54 video model variants across 14 families in total, so you can run the same prompt through both and keep whichever result works.
