I built an open source media file compressor with realtime preview

Capsule is a cross-platform open source app for capturing and compressing media files. I originally came up with the idea because I wanted it to be easier to add more images/videos/voice memos to my Obsidian vault without inflating the vault size.
The interface is inspired by squoosh.app which I've loved for several years for compressing images but wished there existed something similar for other media files. I've always felt frustrated with the complexity of compression tools like ffmpeg CLI or HandBrake when I wanted something quick and simple without having to Google how to use it.
Currently runs on macOS, Linux, Windows, and Android. Let me know if you have any feedback!
