@thomasfuchs @Gargron @selea a server storing one video file is one thing, having to store two versions, one of them being a huge 4k file is unfair - instances are going to have to start asking for higher donations just to cover it
4k simply uses more storage space and energy. I'm not saying it's inefficient in isolation, but it is inefficient in comparison to lower quality videos which for almost all cases are perfectly suitable

that said, maybe this is something the more media focussed instances like pixelfed or goldfish.social would be happy to do, not so much for conversational instances in my opinion
