Vibe Coding Reel Fast

Last week, a preschool teacher had a folder full of photos and needed a quick way to turn them into a slideshow video with music for the last day of school. No time to resize and arrange dozens of images in a video editor. She asked if I had a solution, so I vibe coded Reel Fast.

Before I started building with Gemini, I asked AI if it was even possible for a single-page HTML web app to turn images into a video. I assumed the answer would be no, but modern browsers are surprisingly powerful! They can handle image processing, transitions, music, and video export right inside the browser window.

The really important part is that everything happens locally on the device. Photos never need to be uploaded to a server, which means private student images stay on the teacher’s computer.

This is what continues to amaze me about vibe coding. You can start with a real classroom problem in the morning and end up with a working solution before lunch, even if you’ve never built something like it before.

And, I just love having the Teacher Hive platform there to easily publish the HTML.
