How to Choose the Right AI Video Generation Tool
When selecting from the top AI video generation tools, consider your primary use case and compliance requirements:
- Cinematic storytelling: Choose Sora 2 or Veo 3.1 for 4K realism and synchronized audio.
- Social content production: Use Runway for its editing tools and fast turnaround.
- Corporate training and onboarding: Opt for Synthesia or HeyGen for governance and scale.
Key Factors to Evaluate
- Resolution needs: 1080p vs 4K output
- Audio generation: native vs added in post-production
- Compliance: GDPR, SOC 2, or consent requirements
