Hi Folks

I've been working on an autoconversion Bash script to pick up videos and convert them to AV1. Yes, I know converting a source to another source means degradation and yada yada yada, but it's something I can live with as most of my sources are of very high quality to begin with, and I'm going for space-saving. Plus, my eyes aren't what they once were.

The conversion into AV1 I'm mostly happy with. I'm currently going through some old 90s shows which are of lesser quality, so they would need a little help to look better with AV1 by adding some natural film grain, else AV1 makes them look a little bit too clean.

I can easily pop into the script and enable film grain in the variables, or add in a simple option, but that's boring and tedious. Why do that when we can automate the world :)

Where I have got to is using the signalstats filter. The issue I have is I don't know how to analyse it's output enough to work out whether I should or shouldn't enable film grain or not. I know it's subjective either way.

Does anyone have experience with this? The output per frame looks like:

frame:1438 pts:59977 pts_time:59.977
lavfi.signalstats.YMIN=0
lavfi.signalstats.YLOW=0
lavfi.signalstats.YAVG=60.6913
lavfi.signalstats.YHIGH=149
lavfi.signalstats.YMAX=239
lavfi.signalstats.UMIN=91
lavfi.signalstats.ULOW=108
lavfi.signalstats.UAVG=121.955
lavfi.signalstats.UHIGH=131
lavfi.signalstats.UMAX=148
lavfi.signalstats.VMIN=124
lavfi.signalstats.VLOW=128
lavfi.signalstats.VAVG=134.535
lavfi.signalstats.VHIGH=146
lavfi.signalstats.VMAX=154
lavfi.signalstats.SATMIN=0
lavfi.signalstats.SATLOW=0
lavfi.signalstats.SATAVG=9.74682
lavfi.signalstats.SATHIGH=27
lavfi.signalstats.SATMAX=43
lavfi.signalstats.HUEMED=147
lavfi.signalstats.HUEAVG=162.949
lavfi.signalstats.YDIF=0.737433
lavfi.signalstats.UDIF=0.642897
lavfi.signalstats.VDIF=0.162755
lavfi.signalstats.YBITDEPTH=8
lavfi.signalstats.UBITDEPTH=8
lavfi.signalstats.VBITDEPTH=8

I'm happy to analyse a random 60-second segment and then grab an average from a couple of these outputs, but I'm not sure if this is a good method or not. I'm asked a couple of the biggest LLMs, they have come back with older ways that no longer exist in ffmpeg 7.1.

I'm trying not to use too many other pieces of software in this script. The dependencies are fairly simple with ffmpeg, awk, grep, etc., the kind of thing you get on nearly every distro of Linux. Any thoughts and/or ideas?

The blaze has officially ignited!

I created an Omnivore account recently and I started to love it. I thought to self-host it but I didn't have enough time and thought I'd host it later.

I (along with everyone else presumably) got this email today:

We’re excited to share that Omnivore is joining forces with ElevenLabs, the leading AI audio research and technology company. Our team is joining ElevenLabs to help drive the future of accessible reading and listening with their new ElevenReader app.

Next, all Omnivore users will be able to export their information from the service through November 15 2024, after which all information will be deleted.

Though it is quite frustrating, I will not go further in my opinion of this move.

I would just like to let the community know that I'm in the market for an alternative for this... or maybe some help how to self-host it. I don't even know if it will be easy to self-host or if it will be worth it, presumably without updates...

November 2024's Humble Choice is now available with the following eight Steam games.

Does anyone have experience with any of the games and, if so, would you recommend them? Is there anything in here that you're particularly excited to play?

Have you watched any movies recently you want to discuss? Any films you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

I read thinking in systems a primer by Donella Meadows and really found it interesting. I have been struggling to find a follow up book about systems aimed at a reader with intermediate but non specialist Knowledge of systems thinking. They are all either to basic, too advanced, or so dry it’s impossible to concentrate. Has anyone found a good follow on book for this book?
I appreciate this might be a bit of a niche topic!

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.

Find yourself watching tons of great videos on [insert chosen video sharing platform], but also find yourself reluctant to flood the Tildes front page with them? Then this thread is for you.

It could be one quirky video that you feel deserves some eyeballs on it, or perhaps you've got a curated list of videos that you'd love to talk us through...

Share some of the best video content you've watched this past week/fortnight with us!

The other thread about potential spam on the site got me thinking, can/should Tildes hide itself from Google and other search engines (aside from just the main page) to avoid the tentacles of SEO from infiltrating the site? I'm not sure how feasible that is, but I know reddit has the option to prevent your profile from getting indexed by search engines so perhaps that could be applied to the site as a whole.

I currently reside in Pennsylvania. The election season has been vitriolic, hateful and stressful. Even in church they are angry. They are going to fizzle out they are so mad. Even the ones who are kind are interminably irritable. I may sometimes be a partisan, utilitarian to the core, but I do not talk about politics in God's house. I will speak on justice and righteousness, but not in such terms as are popular. I would rather take that one moment in the week to see my neighbors for who they are and not the tribe they belong to. Somehow that is gone. Service on Sunday was not pleasant. You could feel the tension even as people sat listening. Even the children could feel it.

There is an election sign, or several, on every block. Every building zoned for electric screens has rotating ads (for both candidates) on it. It's all that is spoken about. One cannot escape it. It swallows you whole, spits you out again having transformed you for the worse. Have you voted? Did you hear what he said? Oh, keep quiet, that couple at the next table looks like they voted for the wrong one. Did you hear the vice president is coming to town? Horrible traffic, oh just so terrible. All the out-of-towners, coming in, you know who they support. Despicable. Do you have an election day plan? I voted early this year. That's nice. There was a sign in the next yard over. I just wanted to run it over with my car. Don't look at that man, sweetie, he is wearing boots only the wrong people would wear. The neighborhood watch got a report today. Vandalism, keys. Looking to do some election volunteering. Ballots are on fire. Did you hear? Have to go into that neighborhood, and make sure they don't vote for the wrong person. It would be so bad for them. Oh, they don't understand. Honey, bring your pepper spray, you're not safe there. You'll be shot, knifed. It's the crime, you know who they voted for. Do you know where your polling place is? I voted by mail this year. Did you hear what she said? Well, she didn't say it, but he said she said it. Let's get out of here, sweetheart, you know they voted for the wrong one, just look at the cars they drive, they don't care. Real Americans vote for the right one. All these people voting for the wrong one, so poor, so uneducated. I hate the rich. Let's get out of this bar. Go home. Back where it's safe. We can watch partisan election predictions and not be disturbed.

Nothing else has made me want to leave this state more than its unyielding power in the election. It is not democratic for six or seven states to effectively determine the winner of an election. And it is not a good experience as a resident to be given that much attention. It turns you against each other. It turns your civic and neighborly lifestyle into a caricature. It is worse that it is so all-or-nothing. The stakes are so high. Our 19 electoral votes are worth more than gold, because they only come in a package.

The Lord says

And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.

And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.

It is bad for many reasons. But it is only this bad because of the way our electoral system is set up pits us against each other. It does not have to be this way.

Here are my suggestions. If you are a Senator, please tell your colleagues that scroll_lock has issued a decree and make it happen. Perfection is the domain of nerds, I am simply concerned about minimizing the dominance of the two-party system and improving basic human decency.

• State Constitutional amendments mandating some variety of ranked-choice voting. I'm sure there is some mathematically optimal method. I don't care a whole lot which, as long as it is not first-past-the-post. I am less interested in the most "virtuous" system and rather the most useful one in effectively increasing the number of political parties present in an elected body.
• Federal Constitutional amendment forbidding the first-past-the-post method in elections for any federal or state office. (The states can decide how to implement the alternative. I'm not convinced there is any single best option.)
• Adoption of the National Interstate Popular Vote Compact.
  • When it is inevitably ruled unconstitutional: a national Constitutional amendment requiring the allocation of electoral votes in a given state proportionally to the votes of the electorate, rather than a "winner-take-all" system.
  • OR, maybe this is better done at the state level. Not important to me. The legal nerds can battle out the specifics.
• Federal Constitutional amendment not only forbidding faithless electors but invalidating the votes of any faithless elector. In other words, that "real" vote for the president in December should become a formality only.
  • May as well get rid of this silly meeting while we're at it.
• Federal Constitutional amendment separating the office of president into two equal offices within the executive branch, to be elected in a staggered configuration following the same system of presidential terms we currently have, just offset:
  • President 1: head of state
  • President 2: head of government
• Federal Constitutional amendment forbidding so-called "independent expenditure-only committees" from collecting annually more than an amount to be designated by Congress for political purposes, from any particular entity.
• Federal law forbidding the spending of campaign funds on public political advertising more than 3 months ahead of the election.
• Federal law forbidding the spending of PAC or equivalent funds on political advertising in support of a particular candidate more than 1 month ahead of the election.

And there we go. Not going to solve every problem, but that is the worst part done with.

Godforsaken land. I am buying extra food tomorrow. Let's hope it is over and done with by the end of the week.

Lately I have seen a few posts here and there from accounts that have been silent for a while, where I can't help but feel that these new posts are made by different people or that the initial posts they made were intended to "pad" the account. In other words, they feel a bit like spam and because of that I would like to "flag" them somehow.

The obvious question people will have is likely "Why not just comment about it under the post?"

I have done that various times, and it has the opposite effect of what I'd like:

1. Commenting boosts the post for people who sort based on comments or activity.
2. From what I have observed, when a post has one comment, it is more likely to receive more votes as well. If it has more than one comment, it will receive more votes. This, to me, bizarre voting behavior is something worthy of a meta discussion in itself. But from what I gather, people seem to think that it indicates discussion. Making them think that there must be something worthwhile about the post. This obviously doesn't apply when it's just the OP sharing a quote and me raising a concern.
3. Sometimes I am not entirely sure and would like to have someone with more insights behind the screens take a look at it. If I commented my suspicions while being wrong, that would suck for everyone involved.

Basically for the first two points I am not sure what a good solution would be. I am not advocating for a downvote ability, though something would be nice.
For the third point, I guess I am saying that I am missing the ability to report a post. With comments, I can use the malice label and write out a report, for posts there is no such thing.

And Sao Paulo completes the triple-header!

What a weekend. What a day. What a race! Rain, amiright? Gotta be the most expensive weekend all year, in terms of destruction.

Congrats to Ocon, Gasly, and all of Alpine! P2 & P3, respectively. No one would've predicted that.

As an RB fan, it's great to see Max back at P1 and extending his championship lead over Norris! The gap has increased to 62pts. Amazing drive, starting at P17 and finishing P1. Plus he kept banging out fastest lap after fastest lap at the front, even with the rain and wet track. Yeah he got lucky with the safety car and red flag, but even before that, he was on form.

On the other side of the garage...Checo, WTH. Can't even pass your junior team's rookie driver? And then letting Hamilton through, as well? I'll just leave it at that.

Props to all the mechanics and engineers for having to fix and rebuild all those cars that got destroyed in Qualifying this morning. Especially Williams. I think Albon's crash was the most disappointing for me. He was provisionally P2 with 3min left of Q3, and I was stoked that he might actually keep it. But then he spun out into the wall. I actually yelled out "NOOOOOOO!" when I saw it happen 😭

Lastly, remember that there are potential penalties for Norris and a few others on the aborted start weirdness at the beginning.

3 weeks until the next race; enjoy the break. REMEMBER: Vegas is a SATURDAY NIGHT race in the US. Adjust accordingly to your local time.

Next race:
