I've been a software engineer for over 30 years and have fairly recently worked with video tech. How about you? We can possibly go back and forth with this for days
Netflix rolled out a new client and a new set of streams. The combination of the two has resulted in drastically improve picture quality. It would seem to be a safe assumption that the encoding has changed.
It seems unlikely to me because there've been no improvements in codecs or encoding tech worthy of the massive amount of time and effort required to re-encode tens of thousands of existing streams.
By "new client" and "new set of encodings" you're referring to the installable PS3 player and the 1080p encodings? Again, it's not reasonable to me
to assume that they reencoded tens of thousands of streams for that, since it wasn't necessary. The initial PS3 encodings were AVC with DD2.0 at the same bit rates as the older VC-1 with stereo WMA ones. I'm sure that it required quite a bit of time and resources to encode and verify those in the first place; that they would go through that again without a tremendously good reason seems unlikely.
Like the other poster, I haven't noticed any generally drastic improvement in PQ in the PS3 player. I have seen some very crisp video on the ones with 5.1 sound, but I've assumed that they were just 1080p encodes. There were also some recent tweets on the Netflixhelps twitter account (here
, from the end of October) which quote numbers in line with what I gave.
