Veo vs Runway vs Kling: compare video workflows
Compare the access route, model and usable results. This source review contains no original benchmark scores and does not declare an overall winner.

Google Veo: What the provider documents
Veo 3.1 generates video with native audio. Gemini API documentation describes 16:9 and 9:16, reference images, first/last frames and extension of existing Veo videos. Resolution and available features depend on the variant and input.
Google Veo: Compare costs correctly
Gemini app, Flow, Gemini API, Vertex AI and third-party platforms have separate billing and limits. Compare the same model variant, resolution, audio and duration on the relevant price page. An app subscription does not establish an included API budget.
Runway: What the provider documents
Gen-4.5 supports text-to-video and image-to-video. Its web documentation lists 2–10 seconds, 720p and Standard or higher access. Editing and other models require task-specific selection.
Runway: Compare costs correctly
Gen-4.5 is listed at 12 credits per second. API credits cost USD 0.01 each, giving USD 0.12 per generated second before tax and extras. This conversion is not a web subscription price. ProRes and PNG sequences incur surcharges; web access depends on the plan.
Kling AI: What the provider documents
Kuaishou describes Kling 3.0 with native audio, multiple shots and generation up to 15 seconds. This is a provider announcement, not a guarantee for every option, region or account tier.
Kling AI: Compare costs correctly
A current direct price was not reliably confirmed here. Check model, credits, billing period, watermark and usage terms in the selected access route before ordering. Reseller pricing is not Kling direct pricing; a general cost advantage is unproven.
A comparable pilot
- Use the same cleared subject, brief, aspect ratio and audio goal. Record variants and inputs.
- Run multiple attempts within a fixed budget: assess subject fidelity, motion, continuity, audio and editability separately.
- Divide total generation and post-production costs, including failed attempts, by the seconds actually usable.
- Before uploading, check rights to people, voices, music and assets, plus contract, processing and retention. Company headquarters alone do not establish data residency.
