Three players now lead the pack: <strong>Sora<\/strong> (OpenAI), <strong>Runway<\/strong> (Gen-4) and <strong>Kling<\/strong> (Kuaishou). Each has its own signature and blind spots. We put them through 12 identical prompts to answer the only question that matters: <strong>which to choose, and for what<\/strong>.<\/p><h2>How the test was conducted<\/h2><p>12 representative prompts were generated on each platform with the same parameters (5 seconds, 16:9 ratio, maximum quality). Categories: product, urban scene, landscape, character animation, action scene, micro-cinematic, motion design.<\/p><p>Each generation is scored on 5 criteria: <strong>prompt fidelity<\/strong>, physical coherence, visual quality, camera control, usability (editing, retouching). Three people score independently to reduce bias.<\/p><aside><p>Acknowledged limitation<\/p> A test on 12 prompts doesn&#8217;t cover everything. Seed and prompt variations can flip a ranking on a specific case &#8211; think of this comparison as a guide, not absolute truth. <\/aside><h2>Sora &#8211; raw quality<\/h2> 9 \/ 10 Visual quality 9 \/ 10 Physical coherence 6 \/ 10 Creative control <p>Sora remains the reference for <strong>physical fidelity<\/strong>: reflections, shadows, organic movement. On landscapes and complex scenes (crowd, water, changing light), the rendering is a notch above.<\/p><p>Weakness: <strong>creative control<\/strong>. No motion brush, no precise keyframes, no as-flexible image upload as Runway. It&#8217;s an excellent tool for isolated shots, harder to integrate into an editing workflow.<\/p><aside><p>For whom?<\/p> Studios and creators who want <strong>the best quality per shot<\/strong>, and who already have an external post-production workflow. <\/aside><h2>Runway Gen-4 &#8211; the Swiss Army knife<\/h2> 8 \/ 10 Visual quality 7 \/ 10 Physical coherence 9 \/ 10 Creative control <p>Runway wins on <strong>creative control<\/strong>: motion brush, image-to-video, camera control, lip-sync, extension tools, video in-painting. It&#8217;s a <strong>small Final Cut<\/strong> + AI.<\/p><p>Raw quality lags Sora on complex scenes, but integration into a real workflow is far superior. For anyone who <strong>iterates, edits and refines<\/strong>, it&#8217;s the most practical tool.<\/p><aside><p>For whom?<\/p> Videographers, marketers, freelancers who deliver finished videos and want a <strong>complete workflow<\/strong> without changing tools 10 times. <\/aside><h2>Kling &#8211; the very serious outsider<\/h2> 8 \/ 10 Visual quality 9 \/ 10 Human movement 7 \/ 10 Creative control <p>Kling impresses with <strong>faces, bodies, dances<\/strong>. Where Sora makes beautiful abstract scenes, Kling makes credible choreography. It&#8217;s the only one offering <strong>2 minutes<\/strong> in queue &#8211; useful for narrative use cases.<\/p><p>Main friction in France: interface partly in Chinese depending on version, and random generation times at peak hours. The <strong>quality\/price ratio<\/strong> remains unbeatable.<\/p><aside><p>For whom?<\/p> Creators focused on <strong>human characters<\/strong>, TikTok \/ Reels, music video, and anything involving moving bodies. <\/aside><p>Newsletter<\/p><h3>Receive AI insights, once a month<\/h3><p>Analyses like this one, no hype, no spam.<\/p><label> Email <\/label><button type=\"submit\">Subscribe<\/button><label> I agree to receive the newsletter &#8211; see <a href=\"https:\/\/comparateur-ia.io\/en\/privacy-policy\/\">privacy policy<\/a>. <\/label><button type=\"button\">Unsubscribe<\/button><h2>12 prompts, 3 tools<\/h2><table><thead><tr><th>Test case<\/th><th>Winner<\/th><\/tr><\/thead><tbody><tr><td>Cosmetic product shot on marble background<\/td><td>Sora<\/td><\/tr><tr><td>Skater in street, slow-motion<\/td><td>Kling<\/td><\/tr><tr><td>Drone over mountain landscape<\/td><td>Sora<\/td><\/tr><tr><td>Character dancing in a box<\/td><td>Kling<\/td><\/tr><tr><td>3D motion-design logo<\/td><td>Runway<\/td><\/tr><tr><td>Car crossing a bridge<\/td><td>Sora<\/td><\/tr><tr><td>Interview lip-sync<\/td><td>Runway<\/td><\/tr><tr><td>Illustrated 2D animation<\/td><td>Runway<\/td><\/tr><tr><td>Stadium crowd, wide shot<\/td><td>Sora<\/td><\/tr><tr><td>Dish cooking zoom dolly-in<\/td><td>Runway<\/td><\/tr><tr><td>Martial arts fight<\/td><td>Kling<\/td><\/tr><tr><td>Urban B-roll for vlog<\/td><td>Tie Runway \/ Kling<\/td><\/tr><\/tbody><\/table><p>Overall score: Sora 5 wins, Runway 4 wins (+ 1 tie), Kling 3 wins (+ 1 tie).<\/p><h2>Which to choose based on your use case?<\/h2> \ud83c\udfac <p>Cinema &amp; premium ads<\/p><p>Our choice: Sora<\/p><p>When every shot counts and external post-prod is a given.<\/p> \ud83d\udcf1 <p>Social, ads, quick content<\/p><p>Our choice: Runway<\/p><p>Complete workflow + tools = real velocity.<\/p> \ud83d\udc64 <p>Characters, dance, narration<\/p><p>Our choice: Kling<\/p><p>Credible human movement, long durations available.<\/p> \ud83e\uddea <p>Creative mix<\/p><p>Our choice: Stack<\/p><p>Many teams use all three &#8211; Runway for iteration, Sora for hero shots, Kling for humans.<\/p><figure><blockquote>&#8220;I no longer have one AI video tool.

However, creative control (camera, transitions, retouching) remains more limited than Runway.<\/p><\/details><details><summary> Is Kling worth it? + <\/summary><p>Yes, especially for human faces, dances and character movement. The quality\/price ratio is unbeatable. The barrier remains interface translation and generation time.<\/p><\/details><details><summary> What&#8217;s the maximum duration per generation? + <\/summary><p>Sora: up to 60s in pro mode. Runway: 16-20s standard, extensible. Kling: 10s default, 2 minutes in extended mode (in queue). Adjust to your use.<\/p><\/details><details><summary> Are there restrictions on real faces? + <\/summary><p>Yes, on all three. Sora strongly limits public figures.
