4K60 on YouTube gets you a maximum 1080p60 … for now.

So … it seems uploading 4K60 content gets you a 1080p60 stream but not a 4K30 stream, let alone a 4K60 stream.

Unless a week is not long enough to wait for processing 100mins @ 90GB?  It took 72 hours to spit out the 1080p60 version.


I read (I forget where;  so "here" is good enough) that YouTube's current limit is 200GB.

Ten years ago their first limit was 100MB which, even for the MPEG-4 Part 2 video of the day, was very limiting.  Remember that their duration limit didn't come in for some time until the commercial world discovered rampant piracy was YouTube's "killer app".  (Orthodoxy says it was the Share button and Embed feature).

I foolishly didn't enrol in their "director's account" system before the Google buyout, so ignored YouTube for most of its 10-minute / 15-minute limit era.  Otherwise I could have used some ancient H.264 kung-fu to really squeeze something useful out of that 100MB.

Instead I jumped on the Google Video bandwagon — not the search, but the upload tool.  Yes, that did exist as a YouTube competitor.  I liked it for its 60fps support.

Here's a 480p60 video from Google Video that made the "migration" to YouTube, losing half its frames:

True, YouTube had 240p60 in the beginning, but since I was dying for 576p50 it never occurred to me to test it out.  I was probably too bitter by the 1990s experience of watching American TV via diplexed analogue satellite feeds that linked two NTSC feeds in 240p30 format, worsened by the early-generation electronic standards converters with one-field frame buffers (and no motion interpolation) that made every horizontal edge move with a continuous slow wobble.


And the first-generation studio CCD cameras, which even in NTSC land had no oversampling:

The eyes!  The eyes!  Where are the whites of their eyes!
Anyway.  Let's celebrate YouTube bringing the internet into the 1930s with full motion video since November 2014!
