What is the issue? Big files will inherently have issues, we do not transcode. There is absolutely no need for a five minutes video to be anywhere close to 1.6GiB. HD movies (fully featured movies) can fit in that size at top notch quality. 4K 5M video should be very much under 400MiB.

This is the HD video master file that I would distribute to distrokid or any distributed for my music or videos - for less than $20 a year. Same file I distributed that will come out on traditional distribution on 1/5
It’s too big for sharing. I even created https://apps.apple.com/jp/app/nostr-build-shack/id6752591477?l=en-US to help users overcome limitations imposed by the nostr protocols geared for media uploads
