All FFmpeg-based options were slow and too bulky, so I decided to use the Flutter video_compress package instead.

It supports all levels of compression and handles a wider range of video formats.

Note, after creating subscription to get a real-time compression progress bar. Remember to close that subscription properly before starting a new compression, this was the main reason for the errors during development.

Also this my 2nd flutter project, so I might be doing a lot of things incorrectly

 Nice find! It looks like it uses https://github.com/deepmedia/Transcoder. I might be able to switch to this directly from our current compressor.  

 Sounds great! I'm also thinking about building something more serious—maybe an all-in-one toolkit app with built-in micro-apps and Nostr DVMs for more complex tasks.

Side note: I'm using your Amethyst repo to learn Kotlin, and thanks again for putting so much of your energy into building this amazing app.
