Is there any way to link my paid account to amethyst?
Discussion
If you have nostr.build selected in Amethyst it will automatically link, when you upload something via Amethyst it will go to your account.
For 7min though I highly recommend compressing with Handbrake. It will get it down to a few megs.
If you want an native android options for video compression try out https://play.google.com/store/apps/details?id=com.arthur.hritik.proton.video.compressor&hl=en-US
or
Yeah I was just looking. Gonna give this one a try
