My connection is gigabit actually, thanks for the offer. Lots of people are using Nostr through VPN, or on mobile connections though, which will limit bandwidth. I was offering advice, because I assume you actually want people to view your vlog.
That other version is better, but still not optimal.
Here is a better encode, 720p, 34 mb

Better yet, 480p, 12 mb

You'll note on mobile they look the same, while using a fraction of the bandwidth. You don't need broadcast quality 1080p for social media posts.
Nostr doesn't do media optimization like centralized services, and also lacks HLS to serve appropriate streams for different devices and bandwidths. If you want people to watch your video, rather than scrolling by because it stutters or doesn't load, you need to do it yourself. Just some advice if you want people to actually view your vlogs rather than scrolling by.
