Oh yea, as hosting in nostr is decentralized, relay runners limit the data upload as they bare the cost of hosting your files. Self hosting is an option. I know @nostr.build offers paid hosting, some client do also, you’d have to look into paid plans, or paid relays. I think if you want to get around it for free you’ll have to likit it to short clips. @Kieran is running a streaming service @zap.stream  and there is a video platform called Flare or so, maybe that would be the starting point 

 I heard there is a solution to host on your Google account also 

 what does this mean? 

 someone who stores your files (videos, pictures) so that other people can download them

https://nostr.build is a great service for this 

 How technical are you in general? 

 Technical? I think I'm good. I once mounted the screws of the TV panel.
