Ever shot amazing footage in landscape but need it vertical for social media? Here’s how Runway’s Expand feature solves this problem. I’m taking this classic wide-shot Indiana Jones style temple sequence filmed in 16:9 and converting it to 9:16 for TikTok and Instagram Reels. Instead of cropping and losing half the action, Expand intelligently generates new content above and below – extending the sky with details and adding elements that match perfectly. The AI understands the scene context and creates seamless extensions that feel completely natural. Transform any cinematic footage into mobile-first content without sacrificing your composition. That’s the power of intelligent aspect ratio conversion!
