Veo3 vertical video: Flow 9:16 update

Why 9:16 matters {#overview}

Shorts and Reels default to 9:16. When Google Flow aligns Veo3 output to vertical, your veo3 prompts should state aspect early. This veo tutorial covers framing and safe zones.

Flow & Veo3 vertical {#flow}

In Flow-style workflows, pick portrait / 9:16 before generation. Veo3 benefits from selfie POV, phone held at chest height, tall subject centered so faces stay in the upper third.

veo3 prompts for vertical {#prompts}

Add to every prompt: vertical 9:16, mobile first frame, subject centered, headroom for UI. For product: top-down desk or hero on pedestal filling lower two-thirds.

Use cases {#scenes}

Format	Best for
9:16	TikTok, Reels, Shorts
Safe area	Keep text-critical action in middle 80%

Talking-head, unboxing, fitness reps, street vertical walk—all map well to Veo3 when veo3 prompts repeat the vertical constraint.

Summary {#summary}

Prefer UI 9:16 when the product offers it; otherwise repeat vertical 9:16 in every Veo3 prompt for stable shorts.
