@[email protected] the video on this page is 1440p with a 15k kbit/s bitrate. It is very tolling on low end devices (especially mobile) or non hardware-accelerated renderers, to the point it makes playback impossible.
Consider reducing the bitrate to ~3k kbit/s and video quality to 1080p/720p, or even automatically change the quality based on screen/window size.
@[email protected] lmfao imagine seeing fediverse completely failing and resorting to whataboutism instead of thinking what could be the problem
