    Example; The Office Season 5 Episode 1 comes out under 1GB. However, that same episode on AMZN is 3.9GB? Why does the NF such low bitrate? I noticed this on other series & movies.

    I just noticed on AMZN it's a double episode so let me try single vs single

    Different platforms. If you download the episodes from iTunes it will also be a different size.

    However I do note that Amazon at least seems to go by your settings and presumably bandwidth test on what is listed in the MPD. Depending on days and times I have noticed higher quality streams listed that were not in previous sessions. NF maybe the same? I should note none of this is recent w/ AS just over the years and at different times I noticed that.

    It's a pain as not always easy to get the best quality. As you have to check both NF and Amazon, then go with higher bitrate. Amazon gets even more complicated w/ h265 and VBR and CBR streams (AS doesn't seem to access those). Amazon has 3 different streams that I am aware of for all files, h264 CBR, h264 VBR and h265 VBR. What's the best quality? Will the best quality be available in your MPD if maybe your connection is a little slow etc. It can be a headache.
     
  7. netflix started out somewhere between 10-15Mb/s then they made an announcement that they had tested a new encoding method that even their staff couldn't tell the difference between when given the potential to win a prize (obvious bullshit) and that was just the first of what has been a few decreases in bitrate and what has become a visibly shitty picture. amazon unlike netflix actually has a server farm of some sort so unlike netflix they don't really have to worry about the storage space. as far as quality, there's very little chance amazon will ever be inferior. they do however suffer from being inferior to different regions when the product didn't originate in the US but you can most likely chalk that up to the distributor who sent the files likely trying to save bandwidth/ time. I've gotten shows off itunes in different regions with superior quality to what amazon had on hand.

    as far as " Amazon has 3 different streams that I am aware of for all files, h264 CBR, h264 VBR and h265 VBR" there is damn near a 0% chance this is true. anystream is pulling both CBR files and VBR files where appropriate in relation to the file's age. earliest amzns were 10Mb/s CBRs followed by 15Mb/s max VBRs and finally this third or foruth window appears to be where the scene CBRs started coming in. as far as x265 chances are it's only ever with 4k content and possibly 1080p HDR if they even ever have such a thing. with the bitrates these VBRs have though there's no reason to worry about the CBRs. I've seen Blu-rays that never improved on itunes quality due to encoding methods and source. I would bet on these VBRs being as good as or the best possible quality available the vast majority of the time.

    Netflix 1080p has always been an inferior source to Amazon.
