Seedance 2.5 vs Hailuo 2.3 for AI video
Choose Seedance 2.5 when the job needs a video flagship with text, starting-frame, or multimodal reference input, native audio, and 4-30 second control. Keep Hailuo 2.3 as the cheap fixed image-to-video card when one six-second 768p motion proof is enough.
Seedance 2.5
Kanvora's first video flagship across text, starting-frame, and multimodal reference endpoints with native audio.
- Best fit
- A shot that requires text-only creation, longer duration, native synchronized sound, or image plus video and audio guidance.
- Output
- 4-30 seconds at 480p or 720p with native audio
- Cost
- 480p: 74-552 credits. 720p: 155-1,156 credits; default 5s is 193
Hailuo 2.3 Standard
The separate low-cost Kanvora image-to-video path with one fixed output contract.
- Best fit
- One approved still that needs a restrained six-second motion proof without generated audio requirements.
- Output
- Fixed six-second 768p clip
- Cost
- 24 credits
Compare the same decision criteria
The matrix compares live Kanvora controls, not provider marketing or one cherry-picked clip. Seedance capability comes with a materially higher disclosed credit hold.
| Criterion | Seedance 2.5 | Hailuo 2.3 Standard | Decision rule |
|---|---|---|---|
| Input modes | Text, image, or image plus optional video/audio references | One starting image | Choose Seedance only when the broader input contract changes the job. |
| Duration | Every whole second from 4 through 30 | Fixed 6 seconds | Use Hailuo when six seconds is already the right delivery length. |
| Resolution | 480p or 720p | Fixed 768p | Choose from the actual destination requirement, not the larger model name. |
| Audio | Native synchronized audio always enabled | No native audio control exposed | Seedance is required when generated ambience, sound, or dialogue must be part of the clip. |
| Credits | 74-552 at 480p; 155-1,156 at 720p | 24 fixed | Do not spend flagship credits when the Hailuo contract is sufficient. |
| Reference cost | Video input duration can add verified supplier cost | One image is included in the fixed price | Review the recalculated Seedance hold after attaching a video reference. |

Reserved Seedance proof, real Hailuo boundary
Neither prepared direction below is presented as a rendered comparison. Kanvora will not reuse its Hailuo showcase as Seedance evidence.
Seedance 2.5 flagship 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 into the workbench.

A slow, steady camera push toward the telescope while the paper layers move subtly in the sea breeze. Keep the horizon stable, preserve the original composition, and do not add text or new subjects.

Pay for the capability the shot actually needs
Each scenario starts from a required input, output, or sound boundary rather than treating the flagship as an automatic default.
You have no starting image and need a generated shot with sound.
Signal: The deliverable begins from text and audio is part of review.
Choose Seedance text-to-video.Open Seedance text-to-videoHailuo requires an image and does not expose native audio on Kanvora.
You have one approved still and need only six seconds of quiet motion.
Signal: No native sound, longer duration, or multimodal guidance is required.
Keep Hailuo as the cheap card.Open Hailuo image-to-videoThe fixed attempt costs 24 credits instead of at least 74 Seedance credits.
Character, camera rhythm, and timing come from different files.
Signal: The brief needs an image, a reference video, and an audio cue.
Choose Seedance multimodal reference.Open the Seedance reference pathThat endpoint accepts the three modalities and recalculates video-input cost after verification.
The 30-second 720p tier is tempting but not required.
Signal: The destination can be six seconds and has no native audio requirement.
Stop and use Hailuo or shorten Seedance.Review the 5-second Seedance setupThirty-second 720p Seedance costs 1,156 credits. The tier stays visible precisely so the spend is deliberate.
Treat every endpoint or tier change as a new paid attempt
Changing model, endpoint, duration, resolution, or reference set creates another provider request. Preserve the shot objective and change one requirement at a time.
Switching and handoff costs
- Seedance 720p five seconds costs 193 credits and 30 seconds costs 1,156 credits.
- A Seedance video reference can add billed input duration after the file is verified.
- Hailuo stays fixed at 24 credits for six seconds and 768p.
- An active or UNKNOWN request must settle before another attempt is used as a comparison.
What the comparison cannot prove
- A flagship label does not prove that Seedance wins every visual prompt.
- A longer clip or larger credit hold does not guarantee continuity, identity, dialogue, or sound accuracy.
- The prepared Seedance direction is not a rendered result.
- One existing Hailuo clip cannot establish a universal model-quality ranking.
Keep Hailuo cheap. Choose Seedance only when the flagship contract matters.
