- Sora: OpenAI built Sora to simulate real-world physics; Sora 2 is more advanced, with better physical consistency, more accurate motion, and even synchronized audio. (OpenAI)
- Runway Gen-4: Very flexible, creative, and strong on style. It may not always match Kling’s realism in motion, but it’s powerful for creative scenes using reference images.
Winner for realism: Kling AI is very strong for realistic motion; Sora excels in physically accurate scenes and synchronized audio; Runway is great for creative, stylized visuals.
2. Control and Customization
- Kling AI: Offers a good control panel you can set the first and last frame, choose camera movements, duration, and resolution. (klingai.art)
- Sora: Very flexible. You can remix existing video, extend clips, or start from an image. (OpenAI) You also have some control over aspect ratios and frames. (OpenAI Help Center)
- Runway: Gives templates, reference-image generation, and strong editing tools because it’s built for creative professionals.
Winner for control: Sora or Runway may give more creative control; Kling gives very strong but more structured controls (especially on camera motion).
3. Speed and Usability
- Kling AI: Generally user-friendly. Tools like Dzine (which uses Kling) let beginners upload images or write prompts and generate video easily. (Dzine)
- Sora: Integrated into ChatGPT or Sora app relatively easy to use, though users need to wait for generation. (OpenAI Help Center)
- Runway: More professional; some learning curve; but once you know it, it’s very efficient.
Winner for usability: Kling and Sora are the easiest for non-experts; Runway is powerful but steeper to learn.
4. Length and Resolution
- Kling AI: Supports up to 2 minutes in some contexts (according to Kling’s website) at good resolution (up to 1080p). (Kling AI Video)
- Sora: According to OpenAI, Sora (old version) generates up to ~20 seconds in its web version. (OpenAI Help Center) Sora 2 also supports up to 1080p. (soora2.com)
- Runway Gen-4: Might have limits on length depending on the model and plan; often optimized for short clips.
