    because Iran backs one state that everyone lives in it and refugees have come back.

  • oh dont get me wrong. as I said I agree with most of your original (and now second post).

    my gripe with grain was not about av1 per se. it was with movie makers that add it just because they think it is how movies should be

    this is retarded to me: "Reasons to Keep Film Grain On: Artistic Effect: Film grain can add a nostalgic or artistic quality to video and photography, evoking a classic film look" because the reason is just "nostalgic" that the director has, as in if he was born after digital era, he would have an issue with it and not add it (usually).

    about h264 and transparency, the issue is not that h264 can get that but at high bitrate, the issue is that av1 (as I read) can't get it at any bitrate.

    but overall I agree with you.

    I even recently was shocked to see how much faster av1 encoding has gotten. I would have thought it was still orders of magnitude, but with some setting (like x265 slow setting) av1 is has the same encoding speed.

  • I want to agree with you and I do to a large extend. I like new codecs and having more opensourcy coded is better than using a codec that has many patents. long term patents(current situation) slows technological progress.

    what I don't agree with you is some details.

    first, Netflix youtube and so on need low bitrate and they (specially google/youtube) don't care that much about quality. google youtube video are really bit starved for their resolutions. netflix is a bit better.

    second, many people when they discuss codecs they are referring to a different use case for them. they are talking about archiving. as in, the best quality codec at a same size. so they compare original (raw video, no lossy codec used) with encoded ones. their conclusion is that av1 is great for size reduction, but cant beat h264 for fidelity at any size. I think that h264 has a placebo or transparent profile but av1 doesn't.

    so when I download a fi...I mean a linux ISO from torrents, I usually go for newest codec. but recently I don't go for the smallest size because it takes away from details in the picture.

    but if I want to archive a movie (that I like a lot, which is rare) I get the bigger h264 (or if uhd blueray h265).

    third: a lot of people's idea of codec quality is formed based on downloading or streaming other people's encoded videos and they themself don't compare the quality (as they don't have time or a good raw video to compare).

    4th: I have heard av1 has issues with film grain, as in it removes them. film grain is an artifact of physical films (non-digital) that unfortunately many directors try (or used to) to duplicate because they grew up watching movies on films and think that movies should be like so they add them in in post production. even though it is literally a defect and even human eyes doesn't duplicate it so it is not even natural. but this still is a bug of av1 (if I read correctly) because codec should go for high fidelity and not high smoothness.

  • you didn't do the wrong thing.

    what many people don't notice is that support for a codec in gpu(in hardware) is two part. one is decoding and one is encoding.

    for quality video nobody does hardware encoding (at least not on consumer systems linux this 3050 nvidia)

    for most users the important this is hardware support for decoding so that they can watch their 4k movie with no issue.

    so you are in the clear.

    you can watch av1 right now and when av2 becomes popular enough to be used in at least 4 years from now.

  • maybe, maybe not.

    when h264 was introduced (Aug 2004), even intel had HW encoding for it with sandybridge in 2011. nvidia had at 2012

    so less than 7 years.

    av1 was first introduced 7 years ago and for at least two years android TVs require HW decoding for it.

    And AMD rdna2 had the same 4 years ago.

    so from introduction to hardware decoding it took 3 years.

    I have no idea why 10 years is thrown around.

    and av1 had to compete with h264 and h265 both. ( they had to decide if it was worth implementing it)

  • I get the intel lower power when not doing stuff (wish amd had high/low config for cores too) but what I mean was, in laptop cpus that are not on battery (just connected to power) does amd do more with the same power usage?

    if the comparation can not be done with the same gen cpus from two companies, then maybe a similar power usage cpu from amd and one from intel (laptop of course), do they for example have similar geekbench benchmark results? (for lack of better tool)

    so what I am asking is I dont care that is the same gen amd and intel laptop cpu with both connected to socket power, if amd is better. I want to know if for the same power usage (not idling but working) amd is better or not.

  • care to explain that last part?

    for example if I want to by a new laptop right now, do I buy intel? because it has better power usage? is that only idle and/or lower usage power? what about if I just plus the laptop to power socket always (like a simple desktop), then amd is better with respect to performance per watt?

  • I don't think that is how it works. For example I don't think you can get google security update for older android without updating the whole system. there were monthly google security update that are going to become less frequent.

    Also I think the part that stops the apk installation (those not signed with signature in google database) are checked by google play services and that is installed in background which is the result of project treble and mainline that google implemented for modular updates without rom update. so you probably can't stop google from doing this policy even if you stay on older ROMs.

  • science and medicine mostly prolong life or save lives. they can (in a very limited manner) help somewhat with tiredness at old age. healthy brain function is not improved that much with the help of health industry.

    and we need those who their thinking is not fossilized. I don't mean that as insult, it is just they way of life.

    as I said they can of course be advisers.

    are you saying most 110 years old are capable of holding highest offices? like house of representatives? they need to move alot and talk to alot of people. it is very tiring.

    if not at 110 then at some age most of us are not really gonna be great at those "jobs".

    and another side to my point is that old people are gonna set in their politics and also is they survive the politics circus (many many terms) then they become like a family so they are not gonna rock the boat, so they usually become THE status quo. look at Bernie and his support for jewish isis.

    also they are not really good at fixing new problems (or even old ones) with new tools.

  • yes but the public office, specially the manager, need working brain that can tackle new ideas. I think 80 is too high. I think 70 is too high. maybe set it as the age of retirement.

    they can still be as advisors though.
