[Feedback] First project on Replit: simple vertical → horizontal video converter (with blur)

Hey everyone,

This might be super niche, but I built a quick tool to solve a problem from my remote marketing job. My client shoots everything vertical on his phone, and we needed to upload them to YouTube.

The usual black bars looked plain, and I couldn’t find a fast way to fill them with a blurred version of the video itself (like some news clips do). Most methods I found required downloading editing software, following tutorials, or paying for a premium subscription.

So I hacked together this quick tool. It converts vertical videos into horizontal 16:9 with blurred backgrounds.

Details:

• Cap: 200MB
• No batch uploads yet (maybe later)
• Just looking for feedback — would this be useful for casual editors, influencers, or lazy marketers? Should I add more editing options (i.e. for blur intensity)?

Thanks a ton, excited to hear what you think!
