Parents: don't panic about Momo – worry about YouTube Kids instead | Keza MacDonald | Opinion | The Guardian
The majority of YouTube Kids content isn’t distressing or disturbing – but it is mostly brain-numbingly terrible. A vast amount of the kid-friendly videos that are uploaded are straight-up garbage: cheap, algorithm-driven songs or nonsensical stories featuring 3D models or toys of popular characters such as Elsa, Spider-Man and Peppa Pig. They are designed purely to extract views and thereby money from common search terms – not to entertain or educate kids. Friends with young children regularly complain about the inane surprise-egg or toy review videos that have become household obsessions. My toddler would watch cheap, repetitive, unbearably cheery nursery rhyme videos for an hour if I let him.

The easiest solution for parents of young children might be to purge YouTube from everything – phones, TVs, games consoles, iPads, the lot. This is the approach we’ve taken in our household, which inconveniently contains two video games journalists and, consequently, an absurd number of devices. You don’t need to be a tech luddite to find YouTube Kids both irritating and vaguely worrying. There is no shortage of good children’s entertainment available on Netflix, through BBC iPlayer and catch-up TV, or through advert-free games designed for young players. And there’s zero chance they’ll come across any suicide tips there.

Paywall: The Business of Scholarship
Paywall: The Business of Scholarship is a documentary which focuses on the need for open access to research and science, questions the rationale behind the $25.2 billion a year that flows into for-profit academic publishers, examines the 35-40% profit margin associated with the top academic publisher Elsevier and looks at how that profit margin is often greater than some of the most profitable tech companies like Apple, Facebook and Google.
Staying true to the open access model: it is free to stream and download, for private or public use, and maintains the most open CC BY 4.0 Creative Commons designation to ensure anyone regardless of their social, financial or political background will have access.

How Peppa Pig became a video nightmare for children | Technology | The Guardian
Whether these videos are deliberately malicious, “merely” trolling, or the emergent effect of complex systems, isn’t the point. What’s new is that the system in which such violence proliferates is right in front of us, and visibly complicit, if we choose to see it for what it is. I titled that original essay “Something is wrong on the internet” because it seemed and still seems to me that the issues made glaringly obvious by the scandal are not limited to children’s content, nor to YouTube. First among these is how systems of algorithmic governance, rather than leading us towards the sunny uplands of equality and empowerment, continually re-enact and reinforce our existing prejudices, while oppressing those with the least understanding of, and thus power over, the systems they’re enmeshed in.

Take YouTube’s recommendation system for starters, which doesn’t differentiate between Disney movies and a grainy animation cooked up by a bot farm in China. Essentially what the seemingly benign “if you like that, you’ll like this” mechanism is doing is training young children – practically from birth – to click on the first thing that comes along, regardless of the source.

Tactical Urbanists Form "Human Bollards" On Bikes Lane - CityLab
Along midtown Manhattan’s busy Second Avenue, volunteers from the advocacy group Transportation Alternatives linked elbows to form a chain of “human bollards,” to borrow the title of a short Streetfilms documentary that captured the moment. Grateful cyclists on their way to work high-fived the volunteer human shields, who have been pressing the city to keep its word on properly securing the high-traffic right-of-way.

“These cyclists are so happy to see friendly faces in the morning, and also to have that bumper from moving traffic,” Macartney Morris, an organizer with Transportation Alternatives, tells Clarence Eckerson, Streetfilms director.

When the New York City DOT painted a new lane on 18-block strip of Manhattan’s Second Avenue last year, it was a huge improvement on the spotty sharrows that were there before. But it was a promise only partly fulfilled: The city decided against installing the "tuff curbs”—upright barriers to physically prevent vehicle intrusion—that it had initially proposed. Now, the exposed lane is perennially blocked by trucks and parked cars.

YouTube isn’t removing the selected videos, but is instead setting new restrictions on viewing, sharing and making money on them. A note detailing the changes will go to producers of the affected videos on Thursday, according to a spokeswoman for the Alphabet Inc. company.

Since the videos can still be embedded into external sites, pirates and others are still able to host them on their own pages and get the traffic and ad revenue from doing so.

A little late, but since I had to work on something similar just a while ago there is another solution using fmpeg that I'd like to share:

Choose/create a picture of whatever you want as background in the final resolution of your video (e.g. 1280x720) and type something like this in your console (or create a batch file, whatever you prefer):

Code: Select all
ffmpeg.exe -y -loop 1 -r 24000/1001 -i input_image.jpg -i input_music.mp3 -acodec copy -shortest output_video.mp4

Of course you can adapt this to whatever output you want (e.g. -r 24000/1001 sets fps to 23.976, but you can choose -r 25 as well, or you want not only to copy the music but use another codec, in this case you might use -acodec aac, or you might want to get an avi, then just name the outoutfile whatever.avi . Well, you get the idea: read ffmpeg manual for the settings)

Close Viewing by Austin Allen - Poetry Foundation
When I told a friend I was writing about great poets on video, he guessed right away which poet had sparked the concept. In 1967, Al Alvarez interviewed John Berryman for the BBC, sharing beers with him in a Dublin pub and letting the old lion hold forth. The footage has become legendary in poetry circles, for good reason.

Berryman’s verse is known for its contrarian rhythms, the quirks of emphasis he sometimes signals with fastidious accent marks. Watching him declaim his “Dream Songs,” you realize how physical those rhythms were, how he converted bodily and vocal tics into metrical ones. You see him hunch and rock, stroke his outrageous beard, jab a pedantic finger on the line “this is not for tears; thinking”—and jab even harder as he shouts the word But in an explosive volta.

Sure, he’s drunk, as the YouTube commenters gleefully point out. But sobriety wouldn’t smooth over such spiky eccentricity.

The secret rules of the internet | The Verge
Sometimes exhausted, sometimes elated, and always under intense pressure, the SQUAD reviewed all of YouTube’s flagged content, developing standards as they went. They followed a guiding-light question: "Can I share this video with my family?" For the most part, they worked independently, debating and arguing among themselves; on particularly controversial issues, strategists like Mora-Blanco conferred with YouTube’s founders. In the process, they drew up some of the earliest outlines for what was fast becoming a new field of work, an industry that had never before been systematized or scaled: professional moderation.

Public-Friendly Open Science | Authorea
Scheme of a possible Public-Friendly Open Science bundle.

PFOS should be package in bundles containing papers that are reproducible, interactive and multilayered. Papers should contain all the information to reproduce the described research (including the main code and data). It should also allow the reader to interact with its content, for example through interactive figures. See here for a more detailed description of what the “Paper of the future” should look like.

The important point is that papers should also contain links to “supplementary” documents created for a larger audience. A good start is to include a draft of a press release, where the media can find the most relevant facts and a few quotes from the scientists, and a quick research summary for the layman, where the authors can tell the short story of their work to the general public.

As discussed in the description of the paper of the future, videos are also useful, complementary ways to communicate the results of the research. For example astronomers at Ohio State, when they submit a paper to arxiv, they accompany it by a simple YouTube video that explains the basic idea (they call it “Coffee Briefs”). Together with a quick summary of research, these scientists also get their faces out: this way colleagues can identify them easily at conferences and the public can finally see that scientists are “normal” people, helping to make science more approachable.

Choreography of cyclist behavior
Although it was relatively early in the season and most footage was shot just after the busiest peak period, these nine junctions processed a total of more than 18,500 cyclists in one hour. What is immediately striking is the high percentage of conformists. Although the research was carried out during the morning rush hour and predominantly major junctions were researched, this is still a radically different picture from what's often suggested in the public debate, such as a recent article in the Amsterdam daily newspaper Het Parool about 'the Amsterdam cycling rogues'.

"I laid out three types of pleasure in a foreign language, because that’s how I roll, with definitions taken from the internet. Jouissance, Divertissement, and Schadenfreude. A working hypothesis for why the three examples were sticky or different is because people see them as something that could happen to them but did not. They are also all types of pleasure that have some pain, discomfort, or cringeworthyness attached to them."

What a beheading feels like: The science, the gruesome spectacle — and why we can’t look away -
The al-Qaeda-linked site that first posted the video was closed down by the Malaysian company that hosted it two days after Berg’s execution because of the overwhelming traffic to the site. Alfred Lim, senior officer of the company, said it had been closed down ‘because it had attracted a sudden surge of massive traffic that is taking up too much bandwidth and causing inconven­ience to our other clients’...
The Berg beheading footage remained the most popular internet search in the United States for a week, and the second most popular throughout the month of May, runner up only to ‘American Idol.’
‘The point of terrorism is to strike fear and cause havoc – and that doesn’t happen unless you have media to support that action and show it to as many people as you can,’ said one analyst interviewed by the Los Angeles Times shortly after Nick Berg’s execution. These mur­derers post their videos on the internet because they know that the news media will be forced to follow the crowd. Television news pro­grammes either become redundant by refusing to air videos that are freely available online, or else they do exactly what the murderers want and show the footage to a wider audience.

Anarchist aesthetics and U.S. video activism, text version
This brief historical overview of U.S. anarchist-inflected video practices exposes both the limits and possibilities that undergird them. By addressing anarchism, we can better see the interconnections not only between various video activist formations and their historical trajectory, but also their relations to neoliberal networks and the inequities these groups sometimes perpetuate. Regardless of how one might feel about anarchism, anarchist-based affinities and practices run throughout much U.S. video activism. By failing to acknowledge this long-running underpinning of video activism, we remain blinded to a vast network of individuals and collectives struggling against the gross inequities produced by neoliberalism and its concentrations of wealth. Although their struggles might not be perfect and replicate some of the very injustices they are attempting to overcome, these video activists represent an important part of the mediascape and their working processes have still remained under-analyzed. This essay offers an initial foray into the topic in order to encourage further discussion. It is time that anarchism becomes a frame of reference to understand contemporary video and media activism.

YouTube: Your videos will process faster if you encode into a streamable file format. - Timo Hetzel
YouTube will try to encode chunks from the video as it is still uploading. This also allows them to spread out this single encode job to multiple machines, optimizing load across their nodes and speeding up the process.

In order to do that, they need to know how the data inside the file is laid out. This information is stored in the moov atom of the video container. When locally encoding the file, this information only becomes available at the end of the encode and is therefore appended at the end of the file.

To move the moov atom to the front of the file, one may use the “Fast Start” option of the encoder. QuickTime and others do this in their GUI, ffmpeg users can use the -movflags faststart option, and one may use the qtfaststart script after encoding.

Encoding for YouTube: How to Get the Best Results - Streaming Media Magazine
If you're working with HD video, it's hard to imagine a usage case where you'd want to upload a file smaller than 720p; see above for recommendations there. If you're uploading DV or similar footage, I would heed YouTube's recommendations and convert to a square pixel resolution before uploading. I tested by uploading both 4:3 and 16:9 DV files, and the aspect ratios were slightly off in both. Nothing tragic, but definitely discernible to the trained eye.

Specifically, YouTube encoded the 4:3 DV file to a resolution of 654x480, rather than 640x480, and produced the 16:9 DV file to 854x470 rather than 854x480. Rather than uploading at DV resolutions and aspect ratios, I would convert 4:3 DV footage to a progressive 640x480 file, and the 16:9 DV file to 854x480. Three of the vendors, Adobe, Sorenson and Telestream, provided 640x480 presets, and the data rate ranged from 2 - 2.5 mbps, which sounds about right. The 854x480 file has more pixels, so I would boost this to no more than 3 mbps, with 128 kbps audio good for both resolutions.

So, that's it. Hopefully, you know a lot more about encoding for YouTube upload than you did at the start, with links to get more information should you need it.

Why France Is So Afraid of the Big Bad American Netflix | Renée Kaplan, l'Amie américaine
Either to send a message to Netflix, or simply realizing that the French video content market was about to receive a shock of innovation with which it wasn’t necessarily prepared to compete, Filippetti, the Culture Minister, decided to make some changes.

In July, she announced that feature films could be made available for broadcast on television two months earlier that previously, and reduced the delay for making films available for VOD from three years to two years. These were changes that would allow French broadcasters to be a bit more competitive with Netflix without really having to change their business models or their offers. I don’t want to say this is very “French,” but it certainly isn’t very radical. But it was something.

Conspiracy videos of 9/11 on Facebook: People should be responsible for what they share on social media.
I get that people can waste their time how they like, and freedom of speech means you can publish and share any addled, paranoid rant, but 2.5 million hits is 2.5 million wastes of 2:18. That’s 5 million minutes. That’s closing in on 100,000 hours that people spent watching this hooey.

This is the front line against viciousness and madness and anti-science and anti-reason.

I finally figured out why the pure wrongness of this particular waste of time wouldn’t let me go: Not that it was crazy, but that it was so provably—so easily provably—wrong. Global warming? That involves big data, statistics, and debates about weather versus climate, and there’s plenty of room for genuinely well-meaning people to fall into error.

Righting Waco: Confessions of a Hollywood Propagandist < Killing the Buddha
Confessions of a network TV scriptwriter, writing the TV movie of the original raid on Waco, where 4 agents (and 6 cultists) died in a gunfight:
"There’s a Hollywood maxim: A script can be either fast or good... But how could we do that when the opposing points of view were fundamentally irreconcilable? Since the government’s story was the only one available and we were working under deadline, we reluctantly decided to accept the BATF’s “facts” ... The more I learned about what had really happened, the more I regretted the flawed movie I’d written ... Ever since the movie aired, her family had shunned her. “I do forgive you,” she told me. “But I want you to know that your movie destroyed my life.”...Ars longa, vita brevis – art endures, life is short. --August 25, 2001 Phil Penningroth is a freelance writer who lives in Longmont, California.

Watch out for data caps: Video-hungry cord cutters use 328GB a month | Ars Technica
The average cord cutter—a person who watches online video instead of subscribing to a cable TV package—isn't all that far away from going over the typical data usage limits enforced by Internet service providers... cord cutters "consume on average 212GB a month, more than seven times the usage of a typical subscriber. These 'cord cutters' consume an average of 100 hours of video a month and account for 54 percent of total traffic consumed each month."

Across all US Internet subscribers, about 6 percent use more than 200GB a month. The top 5 percent of online video watchers are hitting an average of 328GB a month, Sandvine said. This number represents total data usage, including both upload and download on fixed networks; the data does not include cellular Internet.

We took all 862 videos from four edX courses offered in Fall 2012 and hand-classified each one based on its type (e.g., traditional lecture, problem-solving tutorial) and production style (e.g., PowerPoint slides, Khan-style tablet drawing, talking head). We automatically extracted other features such as length and speaking rate (words per minute). We then mined the edX server logs to obtain over 6.9 million video watching sessions from almost 128,000 students.
