>I think 32 MbPS is the typical average.
Got any information to back that up? I mean, not to be completely doubting, but I probably will be authoring a BluRay for a small film festival soon, and it would be helpful to know if Adobe's presets are completely full of crap.
>Can you explain how a 4K H.264 5MbPS stream can look better than a 1080p H.264 5 MbPS stream?
I wasn't talking about UHD vs. 1080p, I was simply illustrating that for what most people consider "good" quality H.264 you don't need 40MbPS of bandwidth if you're transmitting 1080p.
>I agree that 4K/UHD is totally useless until H.265 becomes available, assuming it really performs as well as people claim.
H.265 is available. AFAIK Netflix is using it for their 4K streams. It's also available in some open source incarnations. Based on my testing, using ProRes sources it's pretty consistently hit the estimated compression ratios.
>Wrong, UltraHD BluRays are supposed to have a 500 GB capacity.
I'm not talking about disc capacity, I was talking about bandwidth for the stream. Also, at last report UHD BluRays are only going to have a 100GB capacity. Also last I checked there were no 20 layer BluRay discs on the market. I'm assuming they are either an unreliable medium or uneconomical to produce (which you'd need to do UHD distribution) since we're still seeing multi-disc releases on BluRay instead of fitting them all on a single disc.
>According to people I've talked to working on BluRay, they don't believe H.265 will save anything close to 50%.
Well, I'm not sure who you're talking to, but my back-of-the-napkin testing shows something around those numbers.
>That's why they think the final bitrate is going to be 60-80.
Well at the point you hadn't even brought up H.265. If they're using H.265 then the 60-80 range would produce more than enough headroom for UHD content.
However, that would still require H.265 to deliver 50% better compression than H.264, since they're putting four times as much visual information into the stream, and if (as you argued) BluRays were using 30-40MbPS as its running bitrate then if (again, as you argued) H.265 wasn't delivering 50% better compression than H.264 then they'd need the stream to be even larger than 80MbPS to avoid looking over-compressed.
Do you have a link?
This is the main page for season 4 and there isn't a choice for the Martell box.
This is the only Martell box I can find and they want 140.00$. Not gonna happen.
Which is highway robbery at that point. Hell, I could buy a series on BluRay for less than that and still get a bunch of bonus features.
