@The Fishcake (nostr.build) any info here mate?

Not yet. I assume by smoothly you mean something similar to YT

Technically, videos cannot be uploaded to Nostr, as relays only store json text notes, they don't store any media at all. There are media hosting services intended to be used with Nostr, but your Nostr notes still just have a text URL that points to where the media is stored. It is then up to each client to determine what they will do with that URL. Whether they will render the media that it points to directly within the client, render it as a URL that can be tapped or clicked on to open the media in a web browser, or render it as plain text. When it comes to videos specifically, how smoothly it will play often depends on how well the video has been optimized for web. Media hosts can help with that, performing optimization for videos that are uploaded to their hosting service, but not all of them do, so your mileage will vary considerably.

No one optimizes videos on Nostr

To optimize a minute of video takes the same resources as optimizing at least 5000 images with the same resolution. About a day of video and it would take more resources to optimize than all images on Nostr

End of the day still comes back to CDN though. For a 5-minute1080p video transcoded to 3-4 web-optimized outputs that'd be like 30 cents or something. But if it went viral then... nevent1qvzqqqqqqypzpwgv8jm36e358cq3qn2unt0hmvzaxejnk9mqrlum9m464qd7v7prqy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qghwaehxw309aex2mrp0yhxummnw3ezucnpdejz7qpqf9ss72h5cqn5zy0e9y5epuumvfgjt0r3xgnrzhllq3eumnjjl75stna6x0

It’s about compute, not really CDN. It would cost $500 max on any sane CDN 1440p anyway. Unless your basis is AWS egress costs

Also yes this does include serving to Asia regions

Yup, even Middle East, Brazil, etc. will eat it up. If $500 for just the US, global will be double at least. (That's CDN after egress from origin storage.) But zooming out I doubt any creator here is going to pay even the low end. Example this Ian Carroll video, I'm pretty sure the CDN costs will have eaten up most or all of the sats he got zapped. He didn't pay those costs of course, but whoever did pay the CDN costs essentially paying him.

Cloudflare Stream for example is $500 to serve anywhere 500K minutes (your example). If your goal is “good enough” RTT (less than 75ms) to *anywhere* then you can get your egress down to $10/TB which would again come out to about $500. Example is Bunny’s volume network. So no, CDNs don’t cost that much, but still. But that’s not the point. CDN doesn’t matter right now, as we don’t even have content transcoding which comes with a large price tag as well.

And wider wider point -- if this is going to scale then users are going to have to mirco-pay for their own video views. Which is a cool model I think actually, just a lot more groundwork.

I don't quite know what you mean by long form video. This 20 minute long Tiny Glowing Screens remix I posted usually loads well for me
