Kling vs Seedance vs Veo 3

Kling Video, Seedance and Veo 3 are three leading video generation models available in runblob through one API. This page compares them on documented parameters: which inputs each accepts, which modes and frames it supports, whether it has native audio and what duration is officially stated. There are no subjective claims about “quality” here — those are easier to judge by comparing a result on the same scene in the playground. Prices are not quoted in the text: per-second rates load from the live catalog on each model page.

This table does not quote prices. Video is billed per second of output and depends on version, resolution and duration; live USD rates load from the catalog on each model page, and the playground calculator shows the estimated cost before you start.

How to choose

Start from the input you already have. If you have no scene yet and want a clip from a description, all three fit. To animate an existing image or build a shot around references, choose Kling Video or Seedance: the current runblob Veo 3 integration works with text. If native audio matters — ambience, effects or dialogue — Google DeepMind describes that as a strength of Veo 3. For a precise transition between two frames or motion transferred from a video, Kling has separate O1 and Motion Control families.

How pricing works

Video is usually billed per second of output, so the total depends on version, resolution and duration, and models with a video reference may include extra input seconds. Compare models at the same duration and frame size rather than by a single number in a rate row. Specific prices are not quoted here: live USD rates load from the catalog on each model page, and the calculator shows the estimated cost before you start.

One API and a shared balance

All three connect through one runblob integration: a single key, one Bearer authorization format and a shared balance — only the version and request fields differ. Build the request in the model’s playground, move the generated cURL into server code, and pass images and video references as service-accessible URLs. Authentication, generation status and webhooks are described in full in the API documentation.

Frequently asked questions

Which model is best for animating an existing photo?

Kling Video and Seedance accept an image and references, so they suit animating an existing frame. The current runblob Veo 3 integration works with text, without image input. Add a service-accessible image URL; local file paths are not accepted.

Which of the models has native audio?

Google DeepMind describes Veo 3 with native audio generation — ambience, effects and dialogue. Native audio is not stated in the model description for Kling Video or Seedance. The available feature set depends on the variant selected in the generation form.

How do I check each model’s generation price?

Prices are not quoted in the text. Open the model page you need: live USD rates load from the catalog, and the playground calculator shows the estimated cost for the chosen version, resolution and duration before you start. Compare models at the same duration.

Do I need a separate key for each model?

No. runblob provides one integration and a shared balance: a single key and one Bearer authorization format are used for all three models; only the version and request fields differ.
