  • M-Discs had merit in the DVD era. It’s a common refrain of those who don’t know the intricacies and read a wired article years ago to claim they mean anything in the Blu-ray era. They don’t.

    Standard Blu-ray Discs have all the technologies that supposedly make m-discs so long lasting and as far as media that isn’t continuously updated and hashed from live storage medium to live storage medium (cold, archival storage unpowered) they are about as good as you’ll get.

    They are much tougher than DVDs. Of course a variety of things go into how long a disc remains readable and without damage to data including luck with regards to no impurities in the batch. Even m-disc themselves based their longest claims off storage in ideal situations like an inactive salt mine (commonly used for archives by governments). Kept out of sun, away from extreme heat (including baking in uninsulated 120 degree F heat all summer year after year), away from high humidity and away from UV exposure to the data side of the disc as well as scratches and such and they should last a quarter to half a century, some more.

    In the Blu-ray era m-discs are just an overly expensive brand.


  • Hamas is a legitimate resistance group exercising their legitimate, legal right under international law to violently resist unlawful colonization, occupation, land-theft, and genocide. They have every right to exist, they have every right to use violence against settlers who should leave and give back the stolen land.

    If you want more moderate types, know that the zionists intentionally crushed them and propped up Hamas to create just this kind of argument and by spouting it you’re carrying water for them. Only the end of the occupation and the formation of a full Palestinian state will result in the breathing room for the creation of moderate groups and opinions.


  • So first it’s client-side scanning for CSAM. Not without some nobility. But the problem is once you wedge open that door it’s technically possible to do it for other things and so you become compelled to.

    It’ll move from just CSAM to stopping and tracking “propaganda” as deemed by them which will be narrow-ish at first (anything pro-Russia, RT links, etc) but gradually expand over time to anything outside the mainstream branded as extremist (and guess what, privacy advocates will definitely fall within that label). And once that’s in place the private stake-holders, copyright holders will come knocking, they’ll say rightly so “hey you have the capability right now, we demand you implement client-side scanning to detect copyright violations” and then that will be ordered by a court, further enshrined by a law and oh look now you can no longer send political thought that the ruling regime disagrees with, can no longer surf the high seas, and so on and so forth. Congratulations and please enjoy living in the “garden” of Europe.



  • China: has like 300 nuclear weapons, none of them stationed outside their country. Has no forward military bases from which to stage or launch attacks, has limited forward radar visibility of incoming attacks. Has a couple SSBM subs which likely operate entirely in the south China sea from which it can launch. Wants to expand to 1000 by 2030.

    Russia: Has over 4000 warheads, most aging. Has no meaningful forward military bases outside their country for staging attacks on the west. Has no meaningful forward radar visibility of incoming attacks from beyond its borders. Has a few SSBM subs from which it can launch.

    US: Has over 4000 warheads, many aging. Has many hidden, classified, constantly operating SSBM submarines which regularly intentionally cruise to the north Atlantic (near Russia), the south Pacific (near China), and a variety of other locations. Has ground-launched missiles, an air delivery system. Has world class sonar (included super-sensitive listening stations bolted to the bedrock of the east and west coasts) and aggressive drone campaigns to hunt and constantly track Chinese and Russian missile subs to allow them a first kill. Has forward warning radar systems positioned thousands of miles from its borders in northern Canada, in Europe, in the Pacific on island chains. In addition has a massive, the most massive spy satellite network in operation constantly watching other powers in incredible detail. Has a space force dedicated to among other things sabotaging Chinese and Russian space assets with kill switches or remote disable explosives which could be used in aggression to blind their enemy first. Of all major world powers will have the most warning and most time to react decisively in case of a full scale launch and attempted sneak first strike on them by either Russia or China. Stations nuclear weapons with allies in “sharing” agreements where the US has final say on their use and launch in countries from the UK to mainland Europe near Russia to Turkey, is considering such an agreement with South Korea right on China’s border.

    But tell me again how the US is backed into a corner in this situation and has no choice but to build more warheads and pour hundreds of billions that could feed, cloth, shelter, and provide healthcare to its people into new delivery systems which will fatten and enrich defense contractors to the tune of hundreds of billions of overage costs if not trillions for systems that may or may not even work thanks to contractor greed and sloppiness.


  • What are you average file sizes for movies and series?

    Movies? 4-8GB for most 60-120 minute features. TV shows. For live action 800MB/episode, 500MB/ episode for animation. For hour long stuff probably 1.2-1.6GB/episode.

    What would you do? what’s your target size for movies and series? What bitrate do you go for in which codec?

    HEVC 10 bit. I target in the 7000-9000kbps bitrate range generally. For animation that can be as low as 3000-5000kbps. Sometimes a bit higher for very grainy old films, occasionally a little lower for grain less modern digital camera work that hasn’t had digital grain added.

    If you want to maximize space savings without losing quality you have to understand what needs more bitrate and what can do with less. Across the board you could do something like CRF 20 but you’d have outliers where you don’t get enough bitrate and those where you still end up with rates of 14,000kbps.

    The above is for 1080p content.

    If you can stand HD video content at 2-3000kbps more power to you but on a large TV I can tell. I think even being reckless and not caring about future-proofing less than 6000kbps is a bad idea for anything but TV shows. Even those I think outside animation you want minimum 2000kbps for 1080p.



  • Unlike the US which has totally forgiven Iran for the embassy thing in the 70s which was half a century ago and as we know now embraces them as brothers.

    And by contrast the US was inviting the attack on its embassy because they had with the help of the British used the CIA (based out of that embassy) overthrown the leadership of Iran and installed a brutal dictatorship. Additionally no lives were lost in the incident itself.

    This is the international law equivalent of barging into your neighbor’s house because you hear them having a domestic dispute and in the middle of pistol-whipping both parties stopping to go to their kid’s room and shoot her in the leg. Do you think if you were that kid you’d be cool with the person who did that with premeditation 20 years later? 40 years later? Or would you blame them forever for being an unhinged maniac who injured you, gave you a token apology that claimed it happened by accident when you knew otherwise, gave you compensation (but only after they got compensation for you for some damage you did to their yard in a fit you had later while feeling powerless after their violence against you) and has basically shrugged the whole thing off while using their connections to the law to prevent themselves ever being prosecuted and going around the community promoting themselves as the arbiter of decency and a paragon of law and order and goodness and continuing to lie about their deliberate intent.

    So why should they forgive and forget what was never fully admitted to? A crime done by a nation that believes itself not bound by laws or convention trying to operate with impunity as the world’s unappointed emperor at the end of the cold war.

    A nation that within the next 6 years no less went on an adventure through the middle east that left hundreds of thousands dead, millions displaced, illegally invaded another nation in Iraq based on lies, etc. This wasn’t a one-off oopsie, this was part of a pattern of behavior. The US has never shown real contrition (which by definition must include admitting it being deliberate instead of trying to obfuscate with lies about it being an accident).


  • DVD’s max out at about 580p (for PAL, NTSC is 480p), resolutions are measured by the number of horizontal lines of pixels (counted from top to bottom of video/screen), not vertical which at 4:3 square aspect ratio on dvds does tend to be 720 pixels (by contrast full resolution HD video’s number of vertical lines is 1920 while it’s horizontal lines are of course 1080, hence 1080p). You’re not the first person to be confused by this.

    Professional encoders who fully understand the encoders and the schemes in use and care about not seeing artifacting or low quality would never intentionally go as low as 300mb for a feature length movie of even an hour. Yes there are people who do such things but they’re not well regarded and it won’t look even passable on anything larger than a phone screen.

    Recognized quality groups that seek low sizes might get an animated feature (less bitrate needed due to lack of fine detail in animation vs real film) in SD quality down to around that. But for most live action content the sizes I see from the best of the best concerned with smaller release sizes are in the 900mb to 1.5GB range for 60-90 minute features.

    300mb for a 90 minute live action feature even in SD is just not going to look good, some of the groups who get those sizes make them look even half-passable by running pre-filters in virtualdub that smooth, reduce grain and detail, etc before passing to the encoder. That kind of thing is way beyond anything you’re going to learn in a few youtube videos though, that’s advanced stuff with scripting.

    Think about it this way, if you shoot for 1GB encodes with 265 or AV1 you can store over 900 movies on a 1tb drive which can be had for well under a hundred dollars.

    I would like the best and fanciest algorithms to have least dataloss.

    There is no magic that will get you where you want. If you want detail preserved you need more bitrate which translates to larger sizes. Modern codecs like HEVC and AV1 mean you need as much as 1/5th the bitrate you needed with old MPEG2/4 encoding schemes used on DVDs, that’s darn good savings but it has its limits.

    Do as you will but anything live action (non-animated) significantly under 1000kbps average bitrate is going to look awful on a 1080p screen and much worse than what it would look like if you popped your dvd in the disc drive and played it from there.

    Opus is fine if you’re not worried about compatibility and just playing on a computer.


  • I really like the one I have. A relative has a much older model and it still works fine too.

    It’s very responsive and the 4k models are quite powerful and future proofed IMO. If you have an iPhone you can quickly use it as a remote too.

    Paired with infuse app it even does local streaming from my media server well.

    And it’s cheaper to get this year’s top of the line Apple TV than it is the 2019 Nividia shield pro.

    Well re-applying thermal paste is a big matter. I’d try stressing it and seeing if you can force it after cleaning the vents.

    So do things to stress the processor and see if you can force it to happen repeatedly. If it is a thermal issue you should be able to cause it by inducing high load. If you can’t it points more towards other issues. A fault in RAM or the motherboard for example, a loose module or connection, etc.

    And just FYI if you need more help in future this community isn’t intended for it. Try posting in a tech or computer help community for a better chance more people engage.


  • Randomly or after a set time of use or intense use? Could be processor is overheating past safety thresholds (new thermal paste could fix this IF that’s the issue).

    I’d try cleaning vents and fans before changing thermal paste though. Could be they’re clogged and not working right.

    Failing that it could be multiple things. But I’d try to address cooling being adequate first. Make sure vents are unobstructed during use. Use it on a flat hard surface, clean the vents with a vacuum and/or canned air duster.


  • As others mentioned having a good encoder is an issue for AAC. And some skills in using it, tuning, etc.

    Nearly all quality releasers now use AC3/EAC3 or FLAC. Tigole is the last one who uses AAC to my knowledge and the rest of the QXR group rolls their eyes at it.

    You’re not going to get a meaningful reduction in bitrate and file size with AAC over EAC3/AC3 without loss of quality. We’re talking maybe you can shave 2-300kbps off an AAC version versus an AC3 5.1 track. And it’s tricky. So much so no one other than that one person I mentioned bothers. At least no one accepted in the higher echelons as competent in creating acceptably transparent encodes.

    If a source has EAC3 (itself capable of up to halving the bitrate required vs AC3) or AC3 I’d recommend keeping it as they tend to already be efficient. They’re also universally compatible as codecs. Re-encode those big 1500kbps DTS tracks and those even bigger monster lossless Dolby and DTS tracks but I’d leave efficient codecs like AC3 alone.

    That said it’s up to you what sounds good. If you’re using lower end stuff and can’t tell the difference after trying a few different test videos with different types of sounds then go for it.




  • Don’t bother with M-discs. They only provided a meaningful advantage in the DVD era. I’ve researched this a bit myself and consensus at least in the data hoarding community is use 2 Blu-ray Discs from two different batches (bought 6 months apart). Which still comes out cheaper or the same as branded M-Discs. (Though that may be overkill and truth be told as long as you test the disc and it’s data done months after writing you’ll tend to catch any rare bad ones)

    Truth is, quality Blu-ray Discs have all the features that would engender M-disc type longevity in the design spec. Just make sure they’re not low to high (LTH) discs which are inferior but always marked as such at least.

    Don’t get no-name cheap ones either, get Verbatim, Sony, some other good Japanese brand. For Verbatim specifically their discs marked MABL on the package are better.

    Always burn data at lower speeds too, less errors.



  • Disgusting that the shutdown note tried to play off their serious issues with grooming and sexual abuse and claim they did a lot. Fuck that asshole.

    Edit: Uh oh I’m being downvoted by his fan boys. The article (and successful lawsuit) say’s exactly what I’m saying and anyone who at scale enables mass sexual abuse of children is an asshole. Omegle had no other uses for most of its existence, hypotheticals sure but as the article mentions in practice it was overwhelmingly full of naked men trying to find women and children to interact with sexually. The site runner was flagrantly negligent.

    Gosh I love certain types, you’ll rightly jump on a pastor who looked the other way for sexual abuse happening in his church as being responsible, yet a guy who runs a big website for years full of abuse is taken at his word as a sweet, innocent, helpless, benevolent advocate for a better web because he talks right. (Never mind he deliberately obfuscated the horrors happening on his website with his closing statement which people here ate up. It takes a lot to lose safe harbor)

    The venture capital dollars started running out. Returns started being demanded. Companies that made slightly improved and/or more accessible versions of more open products extinguished those products using venture capital dollars then started rolling out the enshittification, demands for money, intrusive ads, spying, dark patterns, sabotaging, paid tiers.

    Back in those days the internet was a curiosity. A hobby. A fun thing to share, something a company might hope to break even on or earn minor profits with, these days big profits are demanded, centralization. Addiction to high resolution and size video and image content which is expensive to host and serve. The network effect drained smaller sites and resources, concentrating people in larger venues that had the investment dollars to support them at the cost of their privacy. Combine with search engine optimization and it became harder to even find smaller places. Add in digitally uneducated kids who thought fb and such were most of the internet and never bother to venture beneath the top 6 google results and older people and this is what you have.

    Take something like Omegle. I don’t want to defend what it was for most of its existence as the bad outweighed the good IMO (like 4chan) but something like that if made today would require linking your facebook or google account and serve you video ads every 5 minutes on top of banner ads. But back then it was just something some random guy could make for fun and not think “hmm I need real identities to monetize these people to ad networks to pay for this and turn a big profit selling the data they input”.


  • You are who you say you are to a network though, at least at layer 2.

    If you say you’re one MAC address one time and another next time then so you are.

    Let me give you an example. Let’s say I’m a device trying to connect to a network. Among other things I tell it “can I have an IP address, my MAC address is Majestic”. It says in turn, sure and notes down Majestic and routes or switches things to me when another device says it wants to reach my IP. In Wi-Fi it basically shouts out it has a packet for Majestic and sends it out onto the air with my unique encryption key I previously negotiated and I am listening for packets for Majestic and grab and process that packet. Now if I go back and connect again and call myself Dull it’ll do the same thing. Those names being stand-ins for MAC addresses of course.

    This is simplified of course. And this is why MAC whitelisting is a futile attempt at security.
