I wonder what happened? I have been blown away by some of the older explainer videos from the 40s and 50s, esp. some of the military training videos for vehicle repair, electrical engineering, etc. Very concise and very clear explanations, always with visual examples. Today, we have things like 3brown1blue that are kind of like that, but in general you don't see information transfer like this either online or in school (at least not in my experience).
- dmitrygr 3y agoWhat happened is that the average attention span fell bellow 2 seconds. There is a book. “Amusing ourselves to death”. YOU can watch those videos. The average person today will be bored and tune out.
- Osiris 3y agoThe one about how a differential works is fantastic. It just goes step by step through showing the problem to incremental improvements until the final gearing system is “simple”.
- BurningFrog 3y agoMy guess is that back then producing films was expensive cutting edge technology, and the few films that got made hired the brightest and best, and gave them time to get it right. Today any unemployed bozo can make explainer YouTube videos. That great as a "democratization", but the average quality is obviously lower.
- cj 3y agoSome quick googling shows cinematic film cameras in 1930/40 used to cost $100k-$300k adjusted for inflation. Today, the cheapest Netflix-approved camera is $2k [0] Lower barrier to entry is a blessing and a curse. Signal v noise, etc. [0] https://noamkroll.com/the-3-most-affordable-netflix-approved-cinema-cameras-you-can-buy-right-now/ https://noamkroll.com/the-3-most-affordable-netflix-approved...
- treflop 3y agoIt's even lower. The FS7 on that list is more like $1,000 these days. (Not that I would consider all those cameras on the Netflix list cinematic. Some are geared more towards documentary.)
- ghaff 3y agoAnd not that it's contrary to the $1K price point but, I think, Apple's last event was filmed with iPhones albeit with a lot of expensive lighting and other gear/people.
- BurningFrog 3y agoFilm reels were also a significant cost that's pretty much gone to zero these days.
- ersamsa 3y agoThis is the right answer
- SoftTalker 3y agoThey were produced to convey information, not to generate clicks and ad views.
- cm2187 3y agoYoutube is full of videos like that. A few sample excellent channels: https://www.youtube.com/@animagraffs https://www.youtube.com/@animagraffs https://www.youtube.com/@engineerguyvideo https://www.youtube.com/@engineerguyvideo https://www.youtube.com/@Lesics/videos https://www.youtube.com/@Lesics/videos The problem is more that they are drowned under the volume of content available.
- pjerem 3y agoAlso Jared Owen which does an impressive work of 3D modeling to explain how things and places work. I’m amazed by the level of documentation you have to ingest to model things in such details.
- Gerard0 3y agoWow, thanks for sharing!
- sema4hacker 3y agoIf YouTube had a Dewey decimal style clickable directory it would be a lot easier to find content.
- singleshot_ 3y agoYahoo, more or less. You’re not wrong.
- wormius 3y agorip yahoo directory and dmoz.
- wodenokoto 3y agoA librarian friend had the same complaint. The problem is that libraries Dewey decimals are managed by librarians who want to sort things correctly. YouTube would be managed by uploaders who wants their stuff to be managed _incorrectly_. YouTube recommendations and search is a super interesting problem not just because of the scale but also because uploaders are an adverse opponent, trying to keyword stuff their spam.
- jimbokun 3y agoThose videos were the equivalent of 3brown1blue for their day. With YouTube, there are far more videos of this sort today than there were then.
- roywiggins 3y agoYes, however, nobody has (imho) done it better than The Secret Life of Machines did it back in the late 80s/early 90s: https://www.youtube.com/watch?v=yuUyt9RG7pk https://www.youtube.com/watch?v=yuUyt9RG7pk
- ClassyJacket 3y agoHave you seen Technology Connections on YouTube?
- xandrius 3y agoYeah, a bit dry and it doesn't always hit the spot with the tone. I wanted to like it but couldn't.
- JKCalhoun 3y agoA criticism I have with not just Technology Connections but plenty of similar channels is that each video seems to just be whatever they thought of doing next. I would love something of the same caliber of quality but with a blueprint for an entire series that would cover the compete gamut of a subject. A popular YouTuber mentioned on HN, and deservedly so, is Ben Eater. His series on building a 6502 computer on a breadboard is exactly the kind of blueprint-driven content I would like to see more of. He had a goal of beginning from a clock circuit and ending up with an 8-bit breadboard computer displaying ASCII to an LCD display and he delivered it in a series of chapters.
- z500 3y agoThat series Ben Eater did was really fantastic. Between following along in Logisim and trying a more ambitious design afterwards, it was the most fun I've had in a long time.
- chiph 3y agoIt's simple, yet hard to execute well. Each sentence contains one piece of information to be imparted. The speed of speaking is slower - with emphasis on diction and pronunciation. There is a slight pause between sentences to allow the recipient time to comprehend what was just said. Try it yourself - read some of the comments here in that manner and observe the difference.
- nonameiguess 3y agoI pretty much use YouTube as a MTV replacement to watch music videos only, so won't speak to the quality of instructional material you find there, but I was still in the military as recently as 12 years ago and the training material in the military was still terrific. This includes unclassified material, though I don't know how you'd find it as a civilian if, for whatever reason, you were interested in learning how to perform maintenance on a modern humvee or what not. The technical manuals are all available through Army epubs, but even though they're not classified, you still need a common access card to login and use the site. A lot of them get mirrored somewhere the public can find them, but I would definitely not call the sprawl of where you might find them very searchable.
- mozman 3y agocan a civilian obtain a common access card?
- password4321 3y agoKeyword: ECA
- exikyut 3y agoI'm not in the US, so that sprawl sounds like my only option if I wanted to see what was available. Where should I start looking? If there's enough high quality content, it might be worth it to download entire websites and index everything to classify and surface things.
- SamPatt 3y agoSurvivor bias? Maybe they made plenty of trash explainer videos, and those didn't survive. Though for economic reasons, that's clearly less true than today.
- colordrops 3y agoCheck out Jared Owen's explainer 3D videos on Youtube. some of the best I've ever seen, and relatively recent. Example: https://www.youtube.com/watch?v=Iod6uwUGM2E https://www.youtube.com/watch?v=Iod6uwUGM2E
