Match the platform: Veo and Imagen output tighter when you generate at the target aspect ratio rather than cropping later. Pick the preset that matches your final platform — TikTok 9:16, YouTube 16:9, Instagram 1:1 or 4:5.
Why Aspect Ratio Matters for AI Video
AI video models like Veo, Pika, and Kling generate tighter, more coherent motion when you target the final aspect ratio at generation time — rather than generating wide and cropping. The framing is built into the take.
Common Ratios
- 9:16 (vertical) — TikTok, Instagram Reels, YouTube Shorts
