  1. Re:2-pass vs. quantizer on Goodbye, HD Component Video · · Score: 1

    Yes, it's a huge difference, and the other commenter is wrong about "doing the same thing".

    A single pass can only adjust the bitrate based on what it has already seen, and has to make assumptions about what will come later. In general, single pass encodes won't change the bitrate by very much from frame to frame. Some frames need the equivalent of 40-50Mbps, but if the 50 or so frames before averaged only 10Mbps, most encoders won't jump up to more than about 20Mbps for the next frame.

    Imagine a movie that spends the first 90 minutes being basically talking heads..in other words, not much movement and easy to compress...and then spends the last 10 minutes with full-on action sequences with lots of motion and hard-to-compress images (smoke, fireworks/sparks, etc.). A one-pass encode at an average of 10Mbps will run those first 90 minutes at very close to 10Mbps, using up 90% of the total bits available to the encode. A two-pass encode might average only 5Mbps for the first 90 minutes, leaving 55% of the total bit budget for the remaining 10 minutes, which could be encoded at an average rate of 55Mbps (if Blu-Ray wasn't limited to about 35Mbps max average rate).

    A two-pass encode really isn't about limiting filesize...it's about allocating the bits to the right frames within whatever size gets used.

    I don't think much of that applies to movies scanned at 4K and resized to 1920x1080.

    Even if the original scanner lost half the resolution in both directions, it would still have more resolution than the final product. You might be right about the color losses, but AVC and VC-1 on Blu-Ray seem to do a good job without losing much quality...MPEG-2 is a different beast.

  3. Re:No it doesn't, your cables are bad on Goodbye, HD Component Video · · Score: 1

    My only problem with the switch to HDMI has been that the long cable to the projector is so heavy that the HDMI connectors won't physically hold the cable in place unless they're anchored in place with velcro straps around the cable. It's not a very good connector design from a physical standpoint.

    You need to suspend the cable from the ceiling a few feet before it connects to the projector. Then, the only weight on the connector is that few feet of cable.

  5. Re:i know what you need on Goodbye, HD Component Video · · Score: 2

    Because mine tops out at around 4 TB, that's not that many HD movies unless you compress the crap out of them and then you've basically done what the ICT flag would do, reduced the quality.

    Many Blu-Ray movies are encoded at essentially constant bitrate despite the fact that this is not required to maintain the full quality.

    You can re-encode a 1920x1080/24p movie at about 10Mbps average and be 99% identical to the original 30Mbps encode, as long as you use a 2-pass encode to make sure the bits end up where they are needed. Then, toss out audio and subtitles you don't use, and it's pretty easy to get a movie down to about 10GB with no real quality loss. For movies with wider aspect ratios (where there are black bars encoded into the Blu-Ray), you can get away with even lower bitrates.

    That would give you room for over 400 movies on your media server, which really should be enough for most people.

  6. Re:Wow, that would be redonkulously profitable. on AMD Sale to Dell Rumored · · Score: 1

    The latest Intel chips use the 1155 socket, and motherboards start in about the $100 range, although they are hard to find right now, due to the SATA hardware bug. Look for them by the middle of next month and you'll see that the price is competetive with AMD. You can also get 1156 motherboards as low as $65, and the CPUs are reasonably competitive on price/peformance with AMD.

    The only real advantage AMD has is that if you already have an AM3 motherboard, you can generally drop in a new chip with just a BIOS upgrade. For a completely new system, it's pretty much a wash on the price between Intel and AMD at the same performance level.

    It's apparent from your rant that you aren't a good enough manager to be able to deal with people who know how to get the job done right the first time for all time.

    I suspect you prefer to deal with the currently predominant types of admin:

    • Ones that must have hundred page change-requests to fix a typo in a string, so that anything that needs to get done takes weeks or months.
    • Ones that just change things until the system works, never knowing why it works, but it does get running relatively quickly and without too many errors.

    I have the luck of currently dealing with admins for our datacenter who are a frightening mix of both. If they had just one "veteran Unix admin" who would spend a little more time and do the job right the first time, but not take weeks to do it, things would run a lot smoother.

    And, I'm not kidding about the weeks or months to get anything done, as currently after full testing of changes to web pages (no matter how small), it takes 3 weeks before those changes roll out to the production system, as there need to be two meetings a week apart where the changes get signed off on twice. Meanwhile, these same bozos will patch production database servers without telling anyone. The problem is that their attitude is that the underlying system (OS, DB servers, web servers, etc.) is "theirs" and they make sure it is "correct" ASAP, without regard to the fact that applications need those resources to run. The sys admins don't care that the apps are what are important to the business process, but the "veteran Unix admin" understands that.

  13. Re:Should have never been there. on Microsoft Kills AutoRun In Windows · · Score: 3, Informative

    True in general, but some Windows installation disks do more than just run setup.exe on startup and instead have rather involved scripts in autorun.inf. I had a driver/utility CD for an NAS device that created a menu of the manufacturer's different models via autorun and could not be invoked any other way

    There is no scripting in AUTORUN.INF...it's really just a very simple INI file. The only thing that could be considered a "script" is the ability to run different programs based on the machine architecture and OS version (controlled by square-bracketed INI section heading tags).

    If you trust a disc, you can just open the AUTORUN.INF file with a text editor and copy what is to the right of "open=" and paste it into the start menu run box and it will do exactly what would have happened if autorun was enabled.

    Installing pirated maps requires running an executable to patch your GPS.

    I guess that depends on the GPS design.

    Some have no protection, so updated maps can be used by anybody. Even with maps with some sort of DRM, often it can be removed from the map and again used on any unit. Another method does require you to run a keygen, which could have malware, but a VM would solve that.

    I've never seen a case where you patch the GPS code in any way, though...it's all about removing the DRM from the map, or finding a code so that the GPS unit will be able to decode the DRM.

    In the US, 12K miles per year per car is the baseline for things like depreciation, etc., and many people drive 15K miles per year. This is because the country is bigger, and the required driving (like commuting for work) is generally longer distance. In the same way, optional driving like vacations (or "holiday" for you UK lot) are also longer.

    So, if you only drive 5K miles a year, even at $8/gallon you'd pay less per year in gas than a US driver paying $3/gallon and driving only slightly over the norm (about 14K miles).

    In other words, the smaller the country, the less transportation cost per mile matters.

  17. Re:Wrong. on Netflix Compares ISP Streaming Performance · · Score: 1

    Full HD streams using H264 run around 10Mbps for poorly compressed video (small publishers without a video engineer doing the work).

    Actually, 1080p24 works just fine at 10Mbps average bitrate using H.264 and a two-pass encode, which can get essentially transparent re-encodes of Blu-Ray sources (at least based on PSNR and SSIM results).

    If you can use the two-pass encode as a streaming source and guarantee a video buffer (like Blu-Ray), then it should work fine. For streaming of live 1080p24 (or worse, higher framerates), then you probably need 15-20Mbps average to maintain quality on the single-pass encode. Netflix should be fine for video at 3-4Mbps for 720p24, but they won't be able to afford the bits to allow the audio to be anywhere close to Blu-Ray quality.

    The primary reason Blu-Ray sees average bitrates of 20-30Mbps for 1080p24 is because they can. Once the disc size (25GB or 50GB) is decided on, it doesn't cost any more to fill it with bits. Unfortunately, it actually reduces quality in the scenes that need it because of the 35Mb limit for any single second of video. With a lower average bitrate, then hard-to-compress frames could use the equivalent of 60-80Mbps and not overflow the video buffer.
