AI Video Generators in 2026: Veo vs Kling vs Seedance
Short answer: there is no objective winner. Google Veo 3.1 documents video generation with native audio and creative controls. Kling 3.0 documents multi-shot, native-audio and element-consistency workflows. Seedance 2.0 supports multimodal references, multi-shot generation and editing. Runway Gen-4.5 supports text-to-video and image-to-video. Choose using your own test shots, current access and total delivery cost. OpenAI's Sora web and app have ended, and its API has a published end date, so migrate long-lived work.
Below: the Sora news, a quick comparison, what each model is best at, and how to write a video prompt that actually holds together.
Important: Sora is being sunset
OpenAI discontinued the Sora web and app experiences on April 26, 2026, and says the Sora API will be discontinued on September 24, 2026. If any part of your workflow depends on Sora, plan a migration to an actively supported model before the API deadline.
Quick comparison
| Model | Best for | Strength | Note |
|---|---|---|---|
| Google Veo 3.1 | Video with native audio and creative controls | Text/image prompting, audio and camera controls | Access and limits vary by Google product |
| Kling 3.0 | Multi-shot and audio-video workflows | Native audio, element consistency, multi-shot | Official guide documents clips up to 15 seconds |
| Seedance 2.0 | Multimodal references and multi-shot generation | Image/video/audio references and editing | Official page documents clips up to 15 seconds |
| Runway (Gen-4.5) | Text-to-video and image-to-video workflows | Web generation with documented shot controls | Web guide documents 2–10 second outputs |
| Sora 2 | Migration only | API remains temporarily available | App ended Apr 26; API ends Sep 24, 2026 |
| Wan 2.2 | Free / open-source | Self-hostable | The open option |
The models, in plain terms
Google Veo 3.1. Google documents text- and image-prompted video, native audio and creative controls. Access, output settings and limits vary across Google products, so check the surface used by your team.
Kling 3.0. Kling's official guide documents native audio, element consistency and multi-shot generation, with clips up to 15 seconds. Confirm current plan limits and language support in your account.
Seedance 2.0 (ByteDance). ByteDance documents multimodal image, video and audio references, multi-shot generation, editing and clips up to 15 seconds. It is a candidate for storyboard and image-to-video workflows, not an automatic winner for every shot.
Runway Gen-4.5. Runway documents text-to-video and image-to-video generation with 2–10 second outputs in its web product. Use the current Runway documentation for controls, credits and supported formats.
Also in the field: Hailuo 2.3 is another commercial model, while Wan2.2 is available as an open-source model for teams able to self-host it.
How to choose, by use case
- Ads / B-roll / product demos → Veo 3.1 (realism + native audio), or Runway for tight client control.
- Multi-shot / audio-video workflow → test Kling 3.0 or Seedance 2.0.
- Talking head / dialogue / lip-sync → Veo 3.1, Kling 3.0 or Seedance 2.0 (all do synchronized audio).
- Cinematic multi-shot story → Seedance 2.0 or Kling 3.0.
- Image-to-video (animate a still) → Seedance 2.0.
- Free / self-hosted → Wan 2.2.
What makes a good video prompt
The biggest difference between image and video prompting is motion and stability. A few principles carry across every model:
- One clear action. "She slowly turns toward the window as the camera pushes in." Piling on five movements creates chaos.
- Describe the camera move explicitly — slow dolly in, gentle handheld, static tripod, orbit.
- Emphasise temporal stability — consistent identity every frame, no flicker, no morphing, no drift. This is what separates a clip that feels like film from one that melts.
- Keep one lighting setup and one mood, exactly as with images — contradictions blur the result.
- Note audio if the model supports it — "ambient city sound," "soft piano," a line of dialogue.
A useful mental model: write the prompt like a one-sentence shot description a cinematographer would understand, then add the camera move and the stability cues.
FAQ
Is Sora being discontinued?
Yes. OpenAI discontinued the Sora web and app experiences on April 26, 2026, and says the Sora API will be discontinued on September 24, 2026. Plan new work around an actively supported alternative.
What's the best AI video generator in 2026?
There is no objective winner. Veo 3.1 documents native audio and creative controls; Kling 3.0 documents multi-shot and native-audio workflows; Seedance 2.0 documents multimodal references and multi-shot generation; Runway Gen-4.5 supports text-to-video and image-to-video. Test your exact shot and delivery requirements.
Which AI video model is cheapest?
Pricing changes by plan, resolution, duration and provider. Compare the current quote for the same output settings; Wan2.2 is available as an open-source model if you can operate the required infrastructure.
Which models generate sound?
Veo 3.1, Kling 3.0 and Seedance 2.0 document audio generation or audio-video workflows. Feature availability can differ by product surface and region.
How long can AI video clips be?
Duration limits are model- and surface-specific. Kling 3.0 and Seedance 2.0 document clips up to 15 seconds in their current first-party materials; Runway Gen-4.5 documents 2–10 seconds on the web product. Recheck before production.
Do I need a different prompt for each video model?
The principles are the same — one clear action, a defined camera move, and stability cues. Tools like GoldenPrompts output a clean English video prompt you can use across them.
Want your video prompt built for you? GoldenPrompts assembles a studio-grade English prompt — with motion, camera and stability cues baked in — for Veo, Kling, Seedance, Runway and more. Free to start: 24 hours of everything, no card.
