Nano Banana 2 Outpainting: Expand Frames Without Breaking the Scene

Nano banana 2 outpainting saved me when a vertical phone still needed a 16:9 YouTube canvas. I expand on Generate, then crop.

TL;DR

Job	Tip
Vertical → widescreen	Expand sides, lock subject center
Tight product → lifestyle	Expand environment, keep product scale
Broken edges	Regenerate; don’t “fix” five times
Text near edges	Prefer empty space over invented copy

Expansion prompt

Expand the canvas to 16:9. Continue the environment naturally. Keep the main subject size and identity identical. Match lighting and perspective. No new logos or text.

Soft CTA

Expand on Generate. Thumbs workflow: YouTube thumbnails.

FAQ

Better than crop-zoom? When you need more scene, yes. When you need tighter focus, crop.
Hands/faces at the cut line? Recenter first, then expand.
