In 2020, I quit my tech job to pursue creating content on YouTube full-time. The biggest problem I had with making videos was editing/removing silence from them. (For reference, it takes 1-2 hours to edit 10 minutes of video.) I put aside 2-3 weeks in June to learn video editing technologies (WaveSurfer.js + FFmpeg) and make a proof of concept - this is the result. It's really rough around the edges but saves me some time while editing.
I was originally planning on selling this as a standalone digital product (for $10-20) since I haven't made much money after leaving the industry, but I found another idea worth pursuing. I haven't touched this project in a month and figured that open-sourcing it can help others who may want to take this further.
