- mdp2021 5y ago> 50 kB/s means you'll be downloading a 10min video like 10 hours Very misleading phrasing: you would download in 10 hours a ~10 hours long video, which (of course) could have been downloaded in a fraction of the time. The throttling has the user download at a speed similar to that required to viewing the video.
- emteycz 5y agoI played a random 1080p YT video and the player-reported data rate is at least 2.5 MB/s, peaking to 20 MB/s (cca 10 MB/s average). 4K is of course much more than that.
- mdp2021 5y agoI just took a video as a parameter - a recent engineering animation - and got the following: format 18 - 640x360 AVC1, V+A : ~50kB/s format 22 - 1280x720 AVC1, V+A : ~60kB/s format 137 - 1920x1080 AVC1, V : ~128kB/s format 400 - 2560x1440 av01, V : ~450kB/s format 401 - 3840x2160 av01, V : ~850kB/s Are you sure you are not reporting mega/bits/? When you mention the «player reported data rate», are you sure that is not the "connection speed"? 10MB/s means downloading 36GB/h (one CD per minute, dozens gigabytes per hour)...
- emteycz 5y agoYou're right it's somehow weird. Perhaps the player shows decompressed figures? Check for yourself - right-click on YT video player, show developer/debug info, and there's a chart.
- mdp2021 5y agoI checked that interface (if you mean the "Stats for nerds"), hence I asked you if you were not by chance reading the "connection speed", which could be the closest to the values you reported and may be misleading to a glance.
- marcan_42 5y agoNo, the throttling is much more aggressive than real time. I suspect it's Google's way of sneakily breaking ancient YouTube clients that won't run arbitrary JS as a countermeasure for downloaders, without really breaking them all the way, so users of e.g. ancient smart TVs just think their network is (unusably) slow instead seeing an outright error, so they don't complain en masse that their TV no longer works properly. Typical video bitrates for bog standard 1080p30 will be in the 1MB/s range, so the throttling is around 20x slower than real time.
- mdp2021 5y agoRight: I forgot about the higher end encodings. 50kB/s is a speed similar to that of the "base" 360p ("format 18") - ~100MB every half hour.
- mdp2021 5y agoSorry, one detail (cannot edit the former reply): 1080p30 will be in the 1Mbit/s range (not «1MB/s»). That's maybe ~2.5x slower (not 20x).
