Veo 3.1 vs Seedance 2.5 for AI video
Choose Veo 3.1 for Google-direct 720p, 1080p, or official 4K output, up to three image references, first and last frames, or extension of an eligible Veo clip. Choose Seedance 2.5 for 4-30 second control at 480p or 720p and image plus optional video and audio guidance. Both remain named flagships with native audio.

- Best fit
- A 4-30 second shot or a workflow guided by an image plus optional video and audio references.
- Output
- Every whole second from 4 through 30 at 480p or 720p

Compare the same decision criteria
The matrix compares live Kanvora contracts and documented supplier costs. Reserved proof slots are not a visual benchmark, and a higher resolution or price is not a quality guarantee.
| Criterion | Veo 3.1 | Seedance 2.5 | Decision rule |
|---|---|---|---|
| Duration | 4, 6, or 8 seconds; 1080p, 4K, references, and extension require 8 seconds | Every whole second from 4 through 30 | Choose Seedance for a duration outside Veo's three values. |
| Resolution | Standard and Fast: 720p, 1080p, 4K. Lite: 720p or 1080p, no 4K | 480p or 720p | Choose Veo when 1080p or official 4K is a delivery requirement. |
| Reference guidance | Up to three private subject images on Standard | One image plus optional video and audio references | Choose the model whose reference modalities match the source material. |
| Transition and extension | First and last frames; about +7s extension only from a recent 720p Veo output, up to 20 times | No separate Kanvora transition or extension tool | Choose Veo only when these controls are required. |
| Credits | Standard 8s: 267 at 720p/1080p or 400 at 4K. Fast and Lite are lower | Default 5s 720p: 193. Range: 74-1,156 | Compare the exact duration, resolution, and tier rather than the lowest family price. |
| Provider path | Google direct | ByteDance through fal | Use the provider route required by policy or workflow. |

Compare contracts without inventing a flagship benchmark
Both cards below are prepared directions, not rendered results. Kanvora keeps each proof slot reserved until a source-tracked output from that exact model is approved.
Veo 3.1 Standard direction
One continuous 16:9 dolly shot through a quiet ceramics studio at blue hour. Follow one artist carrying a cobalt vase from the wheel to a wood shelf. Preserve identity, vase shape, shelf geometry, lens, and light. Audio: soft footsteps, distant rain, and ceramic touching wood. No logo, subtitle, jump cut, extra person, or camera teleport.
The CTA carries 8 seconds, 720p, 16:9, and the Standard tier.
Open this directionSeedance 2.5 direction
One continuous 16:9 tracking shot through a rain-lit night market. Follow one cyclist into a covered lane. Keep identity, storefront geometry, and rain direction stable. Audio: synchronized tire spray, chain movement, distant conversation, and rain on canvas. No logo, subtitle, jump cut, extra rider, or camera teleport.
The CTA carries 5 seconds, 720p, 16:9, and native audio.
Open this directionA visual or audio winner would require repeated matched prompts, current model versions, source-tracked outputs, and declared scoring. This page makes no such claim.
Choose the flagship from the hard delivery constraint
Each scenario names one requirement that materially changes the provider request before opening the workbench.
The delivery must be a Google-direct eight-second 4K clip.
Signal: Vendor path and 4K are fixed requirements.
Choose Veo 3.1 Standard.Open Veo Standard 4KStandard exposes official 4K at eight seconds for 400 credits without copying a competitor's larger claim.
The shot needs 18 seconds of continuous action.
Signal: Duration is fixed above Veo's eight-second generation choices.
Choose Seedance 2.5.Open Seedance at 18 secondsSeedance exposes every whole second through 30 without chaining Veo extensions.
Three approved product views must guide one eight-second clip.
Signal: The source material is image-only and subject consistency needs three angles.
Choose Veo Reference Images.Open Veo reference imagesThe Veo reference path accepts up to three private subject images and fixes duration at eight seconds.
Camera rhythm and timing come from video and audio references.
Signal: The brief needs more than image guidance.
Choose Seedance multimodal reference.Open Seedance multimodal referenceSeedance accepts one image plus optional video and audio references and recalculates billed video-input duration.
Treat every model, tier, or extension as a new paid request
Preserve the shot objective, change one hard constraint, and wait for active or uncertain jobs to settle before spending on a comparison attempt.
Switching and handoff costs
- Veo Standard, Fast, and Lite are separate model IDs and credit holds.
- Veo 1080p and 4K require eight seconds; Lite has no 4K tier.
- A Veo extension bills an eight-second Standard tier while adding about seven seconds to one eligible source.
- Seedance reference video duration can add supplier cost after server verification.
What the comparison cannot prove
- A flagship label does not establish a universal visual or audio winner.
- 4K output does not guarantee continuity, identity, dialogue, or factual accuracy.
- Fast or Lite pricing does not predict whether the first output will satisfy the direction.
- Prepared directions and reserved proof slots are not rendered benchmark evidence.
Choose the input, duration, resolution, and provider path before the flagship.
Both CTAs carry legal model IDs, prompts, and supported settings into the workbench. Private references, safety gates, and the final credit hold remain at the authenticated generation boundary.
