Aren&#x27;t they also saying that 5800kb&#x2F;s is not enough for some bits of some movies?<p>I&#x27;ve definitely noticed this - on 1080 full bluray files the bitrate swings enormously - from 2mbit&#x2F;sec up to 50mbit&#x2F;sec (so much so my Chromecast wifi can&#x27;t keep up in high action scenes).<p>So I definitely think they will be able to make improvements to their 1080p content (and definitely 4k content - I don&#x27;t think 25mbit&#x2F;sec CBR is enough IMO).
