We're in 2026 and:
YouTube: 4K60 + HDR + AV1/H.265 no problem
Instagram/TikTok: Clean 1080p60 vertical all day
X: "Here's your 720p H.264 special, sir" even on Premium+
It's actually kind of embarrassing at this point.
@elonmusk keeps talking about turning X into an "everything app" with long-form video and streaming... but the basic video pipeline still feels like it was built in the early 2010s and only lightly patched since.
