And that doesn't sound fishy to you at all........
Even with netflix who are streaming 30fps videos.....
5Mbs recommended for HD streams.
25Mbs recommended for 4k srteams.
They found that Netflix actually uses:
4300-5800 kbps for 1080p@24
16,000 kbps for 4K@60
That's closer to 3x as much bandwidth for 8x the quality.
Optimizing streams for video can be done in a ton of different of ways. Consecutive frames aren't likely to be very different, with 4k consecutive pixels are more likely to be similar.
Yes I am aware of that too..... that's why I was being very generous with google when I said that we should at the very least double their bandwidth if not triple it.
And yes there are a lot of different ways to go about encoding, but the thing is that whatever netflix needs to do for encoding, becomes like 5 times harder when it comes to stadia..... cause all netflix is is a video player. And it has the luxury of buffering video. It also has the luxury of optimizing codecs on a file by file basis (or even a frame by frame) and use that specific profile on that specific file. So when there is that mostly black screen it can get more aggressive on the compression using less of your bandwidth for the active stream allowing it to buffer more of the video.
Stadia cannot do anything I just mentioned above. They have to adopt compression on a service wide basis as opposed to a game by game/file by file/frame by frame basis. And there will never been the option to buffer anything for them.... that is why the actual bandwidth requirement is as high is it is for even their 1080p streams. What you are saying about optimizing is just something stadia cannot do. Because of the very unpredictable nature of a game. With a movie/show whose frame output is fixed and predictable yes you can do things like that. With games, you can't. Google has to assume that at all times you are going to demand the most of their system, and build their system around accommodating that. Thats why you have stress tests.
Don't get me wrong,for people that have like 70Mbs to 100Mbs this will be great for them. They will get completely artifact free streaming cause even when their network/ISP fluctuates (and these things always do) their bandwidth drops to a level that still will exceed what the "true" minimum speed is for 4k/60fps. The rest of us.... wel we won't be that lucky.
Why I have an issue with this is that its obvious google knows about this... and even looking at Phil's quote, its clear they are trying to somehow gloss over this thing. Its misinformation at its finest.
