Veo 3 (Veo3) Review: Where It Shines vs. Where It Stumbles

Veo 3 (sometimes written Veo3) is Google’s latest step-up in AI video generation and editing. It delivers better fidelity, motion consistency, and strong adherence to instructions—great for camera moves, object motion, color grading, and clean scene beats.

Shines: Interprets descriptive, fully fleshed prompts exceptionally well—mention lenses, moves, lighting, and pacing
Stumbles: On-video text (titles, product labels, exact fonts) can be unreliable; add text later for best quality
Best practice: Break ideas into 2–4 clear beats rather than one complex scene

Prompt Framework for Viral Shorts

Hook first 1–2s: write the attention moment (surprise, contrast, big claim)
Motion cues: “fast push-in”, “handheld energy”, “whip-pan”, “object enters frame left→right”
Scene beats: 2–3 shots (fit within ~8s) with one action each; avoid overstuffed scenes
Brand look: color palette, lighting (“neon rim light”), texture (“grain, high contrast”)
Readable overlay: space for captions; safe margins top/bottom for 9:16 (add exact text later)
Dialog lines: script exact lines in quotes (e.g., “We ship in 24 hours”) to improve adherence

Recommended Specs by Platform

Note: Veo 3 (Veo3) currently outputs up to ~8 seconds per generation. Audio is included in the generated clips; you can swap or mix tracks as needed. For longer platform formats, generate multiple clips and stitch or sequence them before posting.
