Vertical Video Cropper - Turn horizontal videos into vertical with AI tracking

👋 Hey Product Hunt! I built this over a weekend (2.5 days) because I saw a friend struggling to make a rugby short. Cropping the video and setting key frames looked annoying, so I coded something up. I think this could be particularly useful for horizontal sport highlights for TikTok, Instagram Stories, and YouTube Shorts. 🎯 **What makes it unique:** • Uses state-of-the-art SAM2 AI for intelligent subject tracking • Automatically keeps your subject centered while cropping • No video editing skills required, just click and process • Perfect for sports highlights 🚀 **What I'm most proud of:** The tracking algorithm is incredibly smooth, it doesn't just crop blindly, it actually understands where the important content is and follows it throughout the video. Perfect timing with the rise of vertical video content across all platforms. Would love to hear what you think and get your feedback! ⚠️ **Fair warning:** It's currently quite slow. Expect up to 10 minutes for processing. This is very much an MVP! 🤝 **Looking for collaborators:** If you're interested in improving this or working on something similar, I'm open to cofounders.
