The five Seedance alternatives worth comparing are Veo 3.1, Veo 3.1 Fast, Sora 2 Pro, Kling 2.6 Pro, and Runway Gen-4.5. Every one publishes a per-second rate, and those rates span roughly 10x at the same resolution. Check the route before you switch models: the same Seedance clip costs $0.15 or $0.36 per second depending on who you buy it through.
Most pages ranking for this query compare Seedance 1.0, a model two generations old, and none of them print a single price from a provider’s own documentation. You get ten tool names, a “best for” column, and no way to work out what a 10-second clip actually costs you.
This guide fixes that. Every number below comes from the provider’s own pricing page or API reference, accessed July 2026, with the source next to it. Then the part nobody covers: the same model sells at three different prices depending on the route, and that gap is usually bigger than the gap between models.
Key Takeaways
Seedance 2.0 is the current documented version. BytePlus publishes 480p through 4K, 4 to 15 second clips, and native audio (docs.byteplus.com, July 2026). Seedance 2.5 was announced but has no published API reference or pricing.
The route costs more than the model. Seedance 2.0 at 720p is $0.15/s direct from BytePlus, $0.18/s on Replicate, and $0.36/s through Runway’s API. Same model, 2.4x spread.
Veo 3.1 Fast is the cheapest name-brand clip with audio. $0.10/s at 720p against Veo 3.1’s $0.40/s (ai.google.dev, July 2026).
Runway Gen-4.5 is 720p only. Runway’s own spec sheet lists 720p, 2 to 10 seconds, 12 credits per second, and no audio row. Ignore the third-party pages claiming 4K.
Kling 2.6 Pro is the cheapest silent clip. $0.042/s at 720p without audio, rising to $0.14/s at 1080p once you turn native audio on (kling.ai, July 2026).
Open weights stop at Wan 2.2. Alibaba’s Wan 2.5 and later are API-only. Anyone telling you Wan 2.7 is Apache 2.0 is wrong.
One subscription covers all of them. DesignerBox includes Seedance 2.0, Veo 3.1, Veo 3.1 Fast, Sora 2 Pro, Kling 2.6 Pro, and Runway Gen-4.5 on one bill, so switching models is a dropdown, not a new account.
What Seedance 2.0 actually does
Seedance 2.0 is ByteDance’s video model, documented on BytePlus ModelArk. It generates 480p, 720p, 1080p, and 4K with 10-bit colour, at 4 to 15 seconds per clip, with native audio available through a generate_audio flag (docs.byteplus.com, July 2026).
Three capabilities set it apart in its published spec. It takes multimodal reference input, meaning image, video, and audio references in a single generation, alone or combined. It supports first-frame and first-and-last-frame conditioning. And it offers the widest aspect ratio set of any model here, including 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16.
ByteDance describes its strengths as multi-shot generation with cohesive shots and structural consistency across high-motion sequences and shot transitions (byteplus.com, July 2026). No other model in this comparison documents video-as-reference input.
One practical limit worth planning around: 4K runs at a concurrency of 1 and 15 requests per minute, against 10 concurrent and 600 RPM for everything below 4K. Batch 4K work accordingly.
Seedance 2.0 sits in the DesignerBox catalog at designerbox.ai/models/seedance-2-0, which matters for the route question below.
The 5 Seedance alternatives compared
1. Veo 3.1 (Google): best for dialogue and long-form
Veo 3.1 generates 720p by default, with 1080p and 4K available at 8 second duration only. Native audio including dialogue is on by default across all variants, and the price already includes it (ai.google.dev, July 2026).
Its distinguishing feature is extension. A clip extends by 7 seconds at a time, up to 20 times, for a maximum of 148 seconds total, though extension drops you to 720p. Nothing else here gets close to that runtime. Inputs cover text-to-video, image-to-video, video-to-video, and up to 3 reference images.
Best for: scripted spots with spoken dialogue, and anything that needs to run past 15 seconds. See it at designerbox.ai/models/veo-3-1.
2. Veo 3.1 Fast (Google): best for volume testing
Same family, one tenth the price at 4K and a quarter the price at 720p. Veo 3.1 Fast is $0.10/s at 720p, $0.12/s at 1080p, and $0.30/s at 4K, with native audio included at every tier (ai.google.dev, July 2026).
For ad testing where you need 20 variants and only two will survive the first round, this is the rate that makes the maths work. Google also publishes a Lite variant at $0.05/s for 720p, though it drops 4K, extension, and video-to-video.
Best for: high-variant ad testing where per-clip cost decides how many concepts you can try. See designerbox.ai/models/veo-3-1-fast.
3. Sora 2 Pro (OpenAI): best for 1080p with native audio
Sora 2 Pro adds resolutions the base model does not carry: 1024x1792, 1792x1024, 1080x1920, and 1920x1080. Output includes native audio. Image-to-video uses the input image as the first frame (developers.openai.com, July 2026).
Pricing is $0.30/s at 720p, $0.50/s at 1792x1024, and $0.70/s at 1920x1080. Extension runs up to 20 seconds per extension, 6 extensions, for a 120 second ceiling.
One caution on duration. OpenAI’s API reference lists 4, 8, and 12 seconds while its video generation guide describes 16 and 20 second generations. Two official pages disagree, so verify against the endpoint you are calling before you build a shot list around a specific length.
Best for: vertical social at true 1080x1920 with sound. See designerbox.ai/models/sora-2-pro.
4. Kling 2.6 Pro (Kuaishou): best for cost per silent clip
Kling 2.6 tops out at 1080p and generates 5 or 10 second clips only, with no durations in between. Native audio is supported but off by default, and it requires 1080p to enable (kling.ai, July 2026).
The pricing is the story. At $0.042/s for 720p without audio, it is the cheapest published rate in this comparison by a wide margin. Turn native audio on and you move to 1080p at $0.14/s. First-and-last-frame conditioning is restricted to 720p.
Worth knowing: Kuaishou shipped Kling 3.0 in February 2026, which adds 4K, 3 to 15 second durations, and multi-shot prompting across 1 to 6 shots. The DesignerBox catalog carries 2.6 Pro.
Best for: silent B-roll, product motion, and looping social where you add sound in the edit. See designerbox.ai/models/kling-2-6-pro.
5. Runway Gen-4.5: best for frame-level direction
Runway’s published spec table for Gen-4.5 lists 720p output, 2 to 10 second durations, 24 or 25 fps, 12 credits per second, and text-to-video plus image-to-video inputs. It requires the Standard plan or above (help.runwayml.com, July 2026).
Be careful with third-party claims here. Runway’s own spec sheet contains no audio row, and lists 720p as the output resolution. Pages claiming Gen-4.5 does 4K with native audio are not citing Runway. At $0.12/s it sits close to Veo 3.1 Fast, and its appeal is Runway’s surrounding toolset rather than raw output specs.
Best for: teams already inside Runway’s editor who want frame-level control. See designerbox.ai/models/runway-gen4-5.
What every model costs per second
Every rate below is the provider’s own published API price, accessed July 2026. Rates that include audio are marked, because a silent clip and a clip with dialogue are not the same product.
| Model | Provider | Max resolution | Duration | Native audio | 720p rate | Top-res rate |
|---|---|---|---|---|---|---|
| Seedance 2.0 | ByteDance | 4K (10-bit) | 4 to 15s | Yes, optional flag | $0.15/s | $0.78/s (4K) |
| Seedance 2.0 Fast | ByteDance | 720p | 4 to 15s | Yes | $0.12/s | $0.12/s |
| Seedance 2.0 Mini | ByteDance | 720p | 4 to 15s | Yes | $0.08/s | $0.08/s |
| Veo 3.1 | 4K | 4 to 8s | Yes, included | $0.40/s | $0.60/s (4K) | |
| Veo 3.1 Fast | 4K | 4 to 8s | Yes, included | $0.10/s | $0.30/s (4K) | |
| Sora 2 Pro | OpenAI | 1920x1080 | See note above | Yes | $0.30/s | $0.70/s (1080p) |
| Kling 2.6 Pro | Kuaishou | 1080p | 5 or 10s only | Yes, 1080p only | $0.042/s silent | $0.14/s (1080p, audio) |
| Runway Gen-4.5 | Runway | 720p | 2 to 10s | Not in spec sheet | $0.12/s | $0.12/s |

Read the top-res column before you read the 720p one. Veo 3.1 at 4K is $0.60/s, and a single 8 second clip is $4.80. Kling at 720p silent is $0.042/s, and the same 8 seconds is 34 cents. That is a 14x range for a decision most people make by brand recognition.
The route costs more than the model
Here is the finding that reframes the whole comparison. Seedance 2.0 is one model with one set of weights, and it sells at three different prices depending on who you buy it through.
| Route | Seedance 2.0 at 720p | Seedance 2.0 at 1080p |
|---|---|---|
| BytePlus direct | $0.15/s | $0.37/s |
| Replicate | $0.18/s | $0.45/s |
| Runway API | $0.36/s | $0.40/s |
Sources: docs.byteplus.com/ModelArk pricing, replicate.com/bytedance/seedance-2.0, docs.dev.runwayml.com/guides/pricing. Accessed July 2026.
Buying Seedance through Runway’s API costs 2.4x what BytePlus charges for it at 720p. No output difference, no capability difference. That gap is larger than the gap between Seedance 2.0 and Veo 3.1 Fast, which means route selection moves your budget more than model selection does.
This is why “which alternative is better” is usually the wrong question. Two thirds of the searches behind this query are people trying to find a workable way to run the model, not people who decided the output is wrong. Pick the route first. Then pick the model.
For the wider arithmetic across a full campaign rather than a single clip, see our breakdown of what AI video generation actually costs.
What about open source
The honest answer is narrower than most pages suggest. Alibaba’s Wan open weights stop at Wan 2.2, released under Apache 2.0. Wan 2.5, 2.6, and 2.7 are API-only, with no weights published in Alibaba’s official GitHub or HuggingFace organisations. Several roundups claim Wan 2.7 is Apache 2.0. Check the repository before you plan around that.
Two other open-weight options are real. Lightricks publishes LTX-2.3, a 22B audio-video model that generates synchronised video and audio in one pass, under the LTX-2 Community License rather than Apache 2.0. Tencent publishes HunyuanVideo-1.5 at 8.3B, generating 480p and 720p with upscaling to 1080p, under a community licence that excludes the EU, UK, and South Korea (huggingface.co, July 2026).
Read the licence before you ship commercial work on any of them. Community licences carry territory and use restrictions that Apache 2.0 does not, and those restrictions are the part that matters for a brand running paid ads.
None of these are in the DesignerBox catalog. They are the correct answer to a self-hosting question, and the wrong answer to a deadline.
How to pick by shot type
Model choice gets easier when you start from the shot instead of the brand.
Spoken dialogue to camera. Veo 3.1, for the native dialogue audio and the 148 second extension ceiling.
Vertical social at full 1080p with sound. Sora 2 Pro at 1920x1080.
Product motion, silent, at volume. Kling 2.6 Pro at $0.042/s. Add music and voiceover in the edit.
Twenty ad variants where eighteen get cut. Veo 3.1 Fast at $0.10/s, or Seedance 2.0 Mini at $0.08/s.
Multi-shot sequence from one reference set. Seedance 2.0, for the multimodal reference input and documented multi-shot consistency.
Anything longer than 15 seconds. Veo 3.1 with extension, or Sora 2 Pro’s 120 second ceiling. Every other model here caps at 15 seconds or below.

Where DesignerBox fits
DesignerBox includes Seedance 2.0, Veo 3.1, Veo 3.1 Fast, Sora 2 Pro, Kling 2.6 Pro, and Runway Gen-4.5 in one catalog, on one subscription. Switching models is a dropdown rather than a new vendor account, a new billing relationship, and a new prompt box to learn.
Video is billed in credits at credits per second times duration, and it is by far the most expensive operation on the platform. Seedance 2.0 runs 12 credits per second at 720p, so a 15 second clip is 180 credits. At the other end, an 8 second Veo clip with audio runs to 6,400.
That last number is worth sitting with. One clip costs more than Premium’s entire monthly allocation of 2,500 credits. Budget video separately from images, where a generation is 5 credits. The Veo alternatives comparison carries the full credit table across all six video models.
Plan allocations are 112 credits on Free, 500 on Basic at $15/month, 1,000 on Pro at $35, 2,500 on Premium at $75, and 8,000 on Ultra at $200. AI video requires Premium or above. Full breakdown at designerbox.ai/pricing, and the full catalog at designerbox.ai/models.
The argument for a catalog over a single model is not that any one model is better. It is that the shot decides the model, and a six-shot ad rarely wants one model for all six. For how the credit maths plays out across a real plan, see how many clips your plan actually buys.
Prompts tuned for this model sit in the Seedance prompts library, and DesignerBox vs Runway covers the closest alternative head to head.
FAQ
What is the best Seedance alternative?
There is no single best one, because the models differ on axis rather than on quality. Veo 3.1 wins on dialogue and clip length, Sora 2 Pro on true 1080p vertical, Kling 2.6 Pro on cost per silent clip at $0.042/s, and Veo 3.1 Fast on price per clip with audio at $0.10/s. Match the model to the shot.
Is there a cheaper alternative to Seedance?
Yes, at published rates. Kling 2.6 Pro is $0.042/s at 720p without audio, against Seedance 2.0 at $0.15/s (kling.ai and docs.byteplus.com, July 2026). Seedance 2.0 Mini is $0.08/s at 720p if you want to stay in the same family. Before switching, check your route, since buying Seedance through a reseller can cost 2.4x the direct rate.
What is the current version of Seedance?
Seedance 2.0 is the current documented version, with Fast and Mini variants, on BytePlus ModelArk (docs.byteplus.com, July 2026). Seedance 2.5 was announced in June 2026, but as of July 2026 there is no published API reference, resolution spec, or pricing for it on BytePlus.
Which Seedance alternative makes the longest clips?
Veo 3.1. Base clips run 4 to 8 seconds, but extension adds 7 seconds at a time up to 20 times, for a 148 second maximum at 720p (ai.google.dev, July 2026). Sora 2 Pro reaches 120 seconds through 6 extensions of up to 20 seconds each. Seedance 2.0, Kling 2.6, and Runway Gen-4.5 all cap at 15 seconds or below.
Is there an open source Seedance alternative?
Partially. Alibaba’s Wan open weights stop at Wan 2.2 under Apache 2.0, and versions 2.5 and later are API-only. LTX-2.3 from Lightricks and HunyuanVideo-1.5 from Tencent both publish weights, but under community licences with use and territory restrictions rather than Apache 2.0. Read the licence before shipping commercial work.
Does Runway Gen-4.5 support 4K and audio?
Not according to Runway. Its own published spec table lists 720p output, 2 to 10 second durations, and contains no audio row (help.runwayml.com, July 2026). Third-party pages claiming 4K or native audio for Gen-4.5 do not cite a Runway source.
Can I use more than one video model without multiple subscriptions?
Yes. DesignerBox carries Seedance 2.0, Veo 3.1, Veo 3.1 Fast, Sora 2 Pro, Kling 2.6 Pro, and Runway Gen-4.5 on one subscription, billed in credits at credits per second times duration. AI video requires the Premium tier or above.
