Practical Tips for AI Video Generation
Writing Effective Prompts
1. Be specific about the subject: Instead of "city at night," try "Times Square at night after rain, neon reflections on wet pavement" 2. Specify camera movement: "dolly in," "slow motion," "time-lapse" 3. Describe the mood: "cinematic," "documentary style," "nostalgic" 4. Define the lighting: "soft golden hour light," "neon reflections"
Tips for Better Quality
- Start with short prompts: Packing too many elements reduces quality
- Use reference images: Adding a reference image alongside text improves intent matching
- Generate multiple versions: Results vary between generations, so select the best one
- Plan for post-production: Use AI-generated video as a base, then polish in traditional video editing software
Summary
AI video generation tools are evolving rapidly, and Sora, Runway, and Pika each have clear strengths. For raw quality, choose Sora; for control, Runway; for accessibility, Pika.
