Detailed Comparison
Veo 3 (Google)
The only model that generates native audio. Perfect for atmospheric content, social media clips, and presentations. 720p, 4-8 seconds. Prompt tip: describe sounds explicitly.
Kling 3.0 (Kuaishou)
Best raw visual quality. Native 4K output with cinematic motion. Great for professional-looking content. 5-10 seconds. No audio.
Sora 2 (OpenAI)
Longest clips (up to 20 seconds) with consistent quality. Cinematic style. Expensive but worth it for longer narratives.
Grok Video (xAI)
Fast generation (under 30 seconds) with native audio. 720p. Great for quick content creation and iteration.
Wan 2.6
About 210 credits for 5 seconds. Up to 15 seconds, 720p. Open weights, so it imposes far fewer style constraints than the closed models. Image-to-video mode available. Quality is good for the price.
Tips for All Models
- Describe motion explicitly: "camera slowly pans left" or "she turns and smiles"
- Keep prompts focused on one clear action per clip
- Shorter is better for quality (5s > 15s for most models)
- Use Image-to-Video for more control over the starting frame
