Last year I built Recut[0], a native Mac app that helps speed up video editing by automating the rough-cut process. It finds silence, gaps, and pauses and removes them, creating a cut list that you can import into editors like ScreenFlow, Final Cut, Premiere and Resolve. Here’s the Show HN [1] from a couple months ago.
I built it because I was making screencasts and cutting out silence + mistakes was 90% of my editing time. This makes it a ton faster. There were some command-line scripts to do a similar thing but I wanted something visual with a fast feedback loop, where I could quickly preview how it would sound and tweak the parameters in real time.
I didn’t know anything about video and had never built anything with Swift before so it’s been a fun way to learn a bunch of new stuff.
