Seedance vs Veo 3 at a glance

The two models share the basics: text, image and video-based generation with sound, in vertical and horizontal formats. They differ most in clip length, reference limits, aspect ratios, languages and availability. Every fact below comes from ByteDance, BytePlus and Google pages, checked on 12 Oct 2026.

A note on names: people still search for "Veo 3", but on the Gemini API Google marks Veo 3 and Veo 3 Fast as deprecated. The facts below are for Veo 3.1 on the Gemini API. Google's video overview now recommends a newer model, Gemini Omni Flash, as the default, and says to use Veo 3.1 when you need "scene extension, last-frame control, or integration with legacy pipelines". Vertex AI was not checked separately.

Every row comes from the vendors' own pages, listed under Sources at the end of this page.

Pricing detail

Google's Gemini API pricing lists, per second of video with audio: Veo 3.1 Standard "$0.40 (720p and 1080p)" and "$0.60 (4k)"; Veo 3.1 Fast "$0.10 (720p)", "$0.12 (1080p)", "$0.30 (4k)"; Veo 3.1 Lite "$0.05 (720p)", "$0.08 (1080p)". You are only charged for videos that generate successfully. On those rates, four 8-second Veo 3.1 Standard clips at 720p (32 seconds) come to $12.80 before any re-generations, and the same four clips on Veo 3.1 Lite at 720p come to $1.60.

For consumer access, Google's US plans page showed Google AI Pro at $19.99/month (a "limited trial of Veo 3.1 Lite") and Google AI Ultra starting at $99.99/month ("video generation with Veo 3.1").

Seedance on the API is billed per token. The BytePlus pricing page listed Seedance 2.5 at 480p or 720p at USD 10.70 per million tokens without video input and USD 6.40 with video input. That table did not parse cleanly when checked, so confirm on the live page. The Dreamina app showed prices in PHP to our location, so its USD prices are not published to us.

Why published comparisons disagree

Most pages ranking for this comparison are written by API resellers and video tool vendors. They mix versions (Seedance 1.0, 1.5, 2.0 and 2.5 against Veo 3 and 3.1), and their verdicts differ. Check the version label on any test you read before relying on it.

Which to use for which ad format

The table below is guidance derived from the published capabilities above. It is not a result of output tests. The two facts that shape it most are clip length (8 seconds for Veo, up to 30 for Seedance 2.5) and aspect ratio (Veo offers 16:9 and 9:16 only).

Format What the format needs What the published specs say Starting point
UGC selfie and story-time 9:16, one consistent face, natural speech Both do 9:16 with audio. Seedance takes your own voice track as reference audio. Veo writes dialogue from the prompt; Google says only English is fully supported Seedance if you bring a recorded voice or work outside English; Veo for English lines written in the prompt
Talking head A long take or a run of jump cuts Seedance 2.5 reaches 30 s in one clip. Veo stops at 8 s, which fits a jump-cut style Seedance for single takes; Veo if the edit is meant to cut every few seconds
Podcast two-shot Two consistent hosts, cuts between singles Veo accepts up to 3 reference images, enough for two hosts and a set. Seedance 2.5 accepts up to 30 images and 10 audio clips Either; Veo's 8-s clips map well to one line per shot
Drama Several characters, many shots, continuity Seedance's reference limits are higher. Veo's first and last frame control and extension (720p) help join shots Seedance for casts larger than Veo's 3 references allow
Animation and claymation One style across every shot Neither publishes an animation-specific feature. Both accept reference images Either, driven by reference images
Product hero shot Product held exactly, high resolution, short clip Veo 3.1 lists 4K on 8-s clips and product reference images. Seedance 2.0 lists 4K Either at 4K, with a product reference image
Brand film Wide framing, longer takes Seedance lists 21:9; Veo lists 16:9 and 9:16 only Seedance for 21:9; Veo 3.1 at 16:9 if the film runs in landscape placements

If you work from the United States through an API, note that the BytePlus Model Services terms say the Seedance API is not available there, while Google's US plans page lists Veo 3.1 access on Google AI Ultra.

Workflow: using both in one project

Using both models on one ad is an option, not a requirement. It adds a step to match look and sound across clips.

Splits that follow from the published features:

  • Drafts on Veo 3.1 Lite, finals elsewhere. Lite is the lowest published per-second rate on this page. Use it to test hooks and shot order, then generate finals on Veo 3.1 Standard or Seedance.
  • Long takes on Seedance, inserts on Veo. Run the speaking shots as long Seedance clips and cut in 8-second Veo shots for product close-ups or cutaways.
  • Continuity with first and last frames. Both accept first and last frames. Export the last frame of one clip and use it as the first frame of the next to keep position and lighting across a cut.

Joining clips into a 15 to 45 second ad

At 8 seconds per Veo clip, a 15-second ad takes two clips, a 30-second ad four and a 45-second ad six. Seedance 2.5 can cover a 30-second ad in one generation, though you will usually cut it into shots anyway.

Ad length: [15 / 30 / 45] s   Aspect: 9:16   Model per shot: [Seedance / Veo 3.1]

Shot 1  Hook      0–3 s    [shot]   Line: "[hook line]"
Shot 2  Problem   3–11 s   [shot]   Line: "[problem line]"     First frame: [last frame of shot 1]
Shot 3  Proof     11–19 s  [shot]   Line: "[proof line]"
Shot 4  Product   19–27 s  [shot]   Reference: [product image]
Shot 5  CTA       27–35 s  [shot]   Line: "[call to action]"

Fixed across shots: [character reference], [voice], [wardrobe], [location], [lighting]
Veo shots: one spoken line per 8-second clip

Rules for the edit:

  • Write one spoken line per Veo clip, short enough to finish inside 8 seconds, so no sentence is split across a cut.
  • Veo extension works only at 720p and only on Veo-generated video. If the ad needs 1080p or 4K, cut separate 8-second clips instead of extending.
  • Seedance audio is mono. Set the final mix to one format and level dialogue across clips from both models.
  • Add captions, offers, prices and logos in the editor, not in the prompt, so each version can change them without re-generating.
  • Seedance's docs give 24 fps in their frame-count formula; Veo's frame rate is not published on the pages checked. Check your downloaded files and conform them to one rate.

Terms and labels

Read each vendor's wording before client work. The quotes below were checked on 12 Oct 2026.

Seedance. Two sets of terms apply depending on how you access it. The BytePlus API terms include an IP indemnity for permitted use of output and state that the service is not available in the United States. The Dreamina app terms describe the app as "generally provided for private, non-commercial use". Both are quoted in full, with links, in Seedance for ads.

Veo (Gemini API). The Gemini API terms say: "Google won't claim ownership over that content. You acknowledge that Google may generate the same or similar content for others and that we reserve all rights to do so." They also say the Gemini API is "for developers building with Google AI models for professional or business purposes, not for consumer use", and users must be 18 or older. Google's Veo docs say Veo videos are watermarked with SynthID.

Labels on the ad platforms. Veo output carries a SynthID watermark, and both TikTok and Meta have their own rules for AI content in ads: TikTok asks for its AIGC label or your own clear disclosure, and Meta applies an "AI info" label in some cases. The rules, with quotes from each platform's policy pages, are in AI-generated content labels on Meta and TikTok ads.

Next step: plan the clips around the script

Seedance's longer clips and Veo's shorter ones change how you cut a 30-second ad, but the script still decides the shot list. Break the script into beats first, then decide which beats need one long take and which can be built from several short clips. One winning script, made in every ad format shows how to break a script into beats and remake it in other formats. The single-tool guides are Seedance for ads and Veo 3 for ads.

If you make finished ads with either model, Anglr pays creators and agencies on performance to remake winning scripts in every format. See for creators or for agencies.

Who this is for

  • Independent AI creators and editors. You make the ads yourself. You know your work performs, so you'd rather be paid on what it does than on a flat fee.
  • AI agencies and studios. You run a team of editors. You write the brief, your team makes the versions, and you're paid on performance because you know your team's ads scale.

Not for you if

  • You only want a flat fee.
  • You're new to editing and not yet confident your ads will perform.
  • You want every shot spelled out for you.
  • You make one style and won't try others.

FAQ

Is Veo 3 still available?

On the Gemini API, Google marks Veo 3 and Veo 3 Fast as deprecated. The current models are Veo 3.1, Veo 3.1 Fast and Veo 3.1 Lite, and Google's video overview recommends Gemini Omni Flash as the default model for video generation.

Can Seedance and Veo both generate audio?

Yes. Seedance generates synchronized sound by default, in mono. Every Veo 3.1 variant outputs video with audio, and dialogue is written into the text prompt.

How long can a Seedance or Veo clip be?

Seedance 2.5 accepts 4 to 30 seconds per generation and the Seedance 2.0 series 4 to 15 seconds. Veo 3.1 generates 4, 6 or 8 seconds, and can extend Veo-generated videos by 7 seconds up to 20 times, to a total of up to 148 seconds at 720p.

Which supports higher resolution?

Seedance 2.0 lists 480p up to 4K and Seedance 2.5 up to 1080p. Veo 3.1 lists 720p, 1080p and 4K, with 1080p and 4K only on 8-second clips and no 4K on Veo 3.1 Lite.

Which is cheaper, Seedance or Veo?

They bill differently. Veo on the Gemini API is billed per second of video in USD; the Seedance API is billed per token. Neither is comparable without your own clip counts, so price a full ad on each from the pricing pages linked on this page.

Which is better for ads, Seedance or Veo 3?

Neither vendor publishes ad results, and published third-party comparisons disagree and often mix versions. Use the format table on this page as a starting point and test the same script on both.
