It's using AAC audio (MP4). I don't think Firefox supports that by default. If your video encoder lets you choose, try MP3, Opus, or Vorbis.
I have no idea why my videos have no sound, (in some clients, not all), when I upload via #Amethyst, using either nostr.build or blossom.primal.net.
Can someone please explain ?

@node I am uploading using Primal client.
After Eight, without speed up.

I am using a phone. I can try to convert audio...but I am not open to upload my videos to convert... 😏
You should be able to do it right on the phone. https://chatgpt.com/s/t_68942cf538908191b6f47ce5146bacc5
