    Yeah, I totally understand. Right now, the CPU time on AV1 lossless encoding is STUPID high, and I'm not sure if there are designs for a hardware encoder yet. I hope it catches on, but we're in the early days for sure. Right now the two best codecs (that are actually out and in use) are HEVC and VP9

    Yes, but there isn't much of a point when AV1 isn't ready to go. Those transistors can be put towards other stuff that's more useful right now.

    We don't have train networks between most major cities in the States, unfortunately. Where possible, I try and take whatever will keep my impact at a minimum.

    AV's lossless compression ratio is quite good. https://www.texpion.com/2018/07/av1-vs-vp9-vs-avc-h264-vs-hevc-h265-1-lossless.html See testing done here. Of note, though, even in lossless mode,...

    https://www.texpion.com/2018/07/av1-vs-vp9-vs-avc-h264-vs-hevc-h265-1-lossless.html

    See testing done here. Of note, though, even in lossless mode, AV1 is technically lossy (still buggy and in development). That was as of version 1.0.0-21-g96ee0eb45 (summer 2018). Updated versions should be fixed now, but obviously, performance will be worse than what is shown in those charts right now.

    Between the two tests (different source footage) we saw 700MB >> 89MB and 330 MB >> 110MB, so somewhere between 3:1 and 11:1 compression ratios depending on the content of the video.

    Just keep in mind it's still buggy and not technically lossless due to some bugs that weren't worked out last summer.

    I very much agree on the presentation style of a keynote. Jobs told stories. About engineering, about features, etc.

    iPhone was okay for me. Honestly, they skipped over so much in the keynote just to fit it all within 1.5 hours.

    I wish we'd gotten a polished finish on the iPhone Pros... but that's okay. Battery life going up by 4-5 hours on the iPhone Pro is a really nice touch. Sadly, they took out 3D touch, and now all the phones have Haptic Touch.

    I know a lot of people who think the current price of $279 is too high.

    Yeah, it makes sense that they'd mark these down, and keep the "newest" watches at a high price. The only company reasonably threatening Apple's dominance in smartwatches right now is Fitbit, and their new flagship is also $199 -- the Fitbit Versa 2. So that $199 Apple watch price is not a coincidence.

    There's also a good reason to buy an EV and road-trip it to various places. Also, as electric planes come into service, it'll be interesting to see if they can provide green travel options.

    That's definitely a good way to look at this -- whether we all like it or not, companies like Apple and Google really do set trends for the rest of tech. It's the same reason that even though I'm an apple user primarily, and my only Google products are their web services, I do watch Google I/O because it's always interesting to see what they've been working on.

    As for price, you'd be surprised, but it's generally fair because it's not just about specs -- it's about how you implement software. And Apple generally doesn't vacuum up user data to target ads and subsidize their services (which is what makes Google's hardware and software cheaper). Nothing wrong with that as long as users are informed - essentially, you can have a split payment (data + cash) with Google, or a single payment type with Apple (cash).

    Funny enough, modern smart TV's are becoming cheaper than their dumb-TV counterparts, because once again, user data is subsidizing the prices! it matters even more in a thin-margin business like TVs.

    Also, keep in mind that Firefox and Chrome are actually on VP9 right now, as AV1 remains experimental.

    Thankfully, Apple and Microsoft are part of the contributing bodies to AV1, and it seems to be the setup for a very good, royalty free, and ultra-compatible future standard.

    It's still in active development though - right now, if you use multithread encoding / decoding with AV1 you end up with 30% smaller file sizes, but you're unable to achieve a lossless transcode (when set to lossless) which is a problem. When using single threaded encoding / decoding, you still cannot create a lossless transcode, although quality is much better. So there is much work to be done.

    When set to Lossy, the codec completely outperforms VP9 and HEVC in file size. The problem is that the current implementation takes a long time to encode / decode, and only single thread decoding is available right now, making it about 20x less energy efficient than HEVC. One of the advantages of HEVC / H.265 over VP9 and AV1 is that it's able to fully utilize all threads at 100% during encode and decode, making it (currently) more energy efficient than either VP9 or AV1 (talking about software decoding here). All this could be solved with an open source hardware encoder/decoder for AV1, but we're a few years away, still.

    I'm not at all dinging AV1 for that, though, because it is early days and it's being actively developed right now, and isn't really deployed to consumers yet, so the flaws are forgivable as long as there are plans to fix them. When comparing current formats, HEVC / H.265 has both energy efficiency and file size efficiency over VP9., further boosted by a hardware encode/decode that lifts efficiency even higher is the reason Apple chose the format. Yes, the royalties are a problem - that business model is unsustainable today, and most of the companies who developed HEVC are now onboard with AV1.

    It should be noted that VP9 also has hardware encoding built into later Intel, Qualcomm, and Samsung CPUs. Apple has Hardware HEVC encoding in the A-series (iOS device) and T-series (mac) chips.

    While Apple hasn't baked AV1 support into any of its software (yet), it did join the AV1 group, Alliance for Open Media -- you can bet they'll only add it when it's mature and hardware support exists. I cannot wait - universal standards are a huge deal.

    Well, this is why this year they're doing the stream on Youtube for everyone else.

    And the reason they aren't changing it up is because the stream is actually broadcast from Apple TV / iTunes servers that send 4K HDR Video to Apple TVs. It's an in-place system being adapted to live stream an event, and there isn't transcode / serve an alternative functionality built in.

    Instead of wasting time developing a feature for a few keynotes a year, they're also live streaming it on their YouTube channel this year... so everyone can watch :P

    I really am unsure of what to think about this Keynote. It could go either way. Apple might surprise us with incredible software features, along with an iPhone 7-like update (where the design is identical to the previous 2 years)...

    Or we could possibly see Augmented reality... and major updates to Apple watch, a new MacBook, new mac pro related stuff... (I still want to see AMD's Rome CPU in the Mac Pro)

    iMacs are the one computer that didn't get a significant update this year. Currently iMacs use the RX 580 GPU from AMD, but they've recently released the 5700 / 5700XT which are more energy efficient, and over 2x faster. Looks like a good drop-in upgrade, along with updating to 9th gen Intel CPU's. Or maybe Ryzen. I hope we see Apple embrace AMD some more, and pass some of those savings onto us... especially when AMD has 12 and 16 core desktop chips. :P

    As for the new watches I think we'll see comprehensive sleep tracking features, and maybe some really nice materials, for the new Edition watches. I hope we see a Titanium Hermes watch.

    But let's assume this entire keynote is very very underwhelming, it may set the stage for a late October keynote where iPads / Macs are updated... Or, they could COMPLETELY turn it around by showing off the most amazing AR glasses at the end of the keynote...

    And I agree -- the iridescent glass looks so good, I'm sad it'll be taken away.

    In a rare move for the company, they just stated they will be giving 3rd party repair shops access to official tools and parts to continue supporting out of warranty Apple devices.

    A major step in the right direction for right to repair, from a company that often sets the trends for other tech companies (for better or worse).

    The program will require at least one person at each business to have a Mac or iOS technician certification (apple offers classes for this), and they are specifically not giving these parts out to resellers who will just mark them up and sell them to anyone, but rather to repair shops with trained people who continue to fix apple devices.
