   PSA: if you upload stuff to youtube, I highly recommend upscaling your videos to 4K first even if they're 1080p.

   they've tanked the bitrate on 1080p, even on premium now, and it looks awful. it's particularly problematic on anything with lots of hard cuts because the keyframe intervals have been stretched out. the very second you go up to 1440p or 2160p source it fixes it.

   I've seen multiple creators have to reupload videos because they look so bad, and it hurts their views as a result.

     I suspect there's also something else going on beyond the bit rate reduction, because if you upload a 4K video but watch the 1080p transcoded stream it's nowhere near as bad as uploading a 1080p video and watching at 1080p. my guess would be that they've semi-recently cost-optimised their transcoder in a way that ends up producing worse results for same-resolution conversion.
