When you train to be a teacher, most of what you have to learn os dreadfully dull, but some bits really stick in your head. Most is to do with communication. Two way communication works best, and we can interrupt when we get lost - which is why the delay on the TV interviews with policiticans is so horrible. The delay wrecks the two-way process. One way communications, like Youtube goes wrong because the person sending the info has to guess on the level of the viewer. Most click aways on YouTube are because the information is presented at too higher level, or too low a level. When there is a match - you watch. This is why many do intro level videos, then have a separate higher level. "if you want to know more in depth info on XYZ, click on the link below.." type stuff. How many unboxing videos stop at exactly the point you want to start? Too many. Or maybe you just make the video in sections - the basic info first, followed by the deeper stuff. One way comms, when it fails, is usually due to level mismatches. With any technical subject that needs to be presented to non-technical viewers - you need to keep the level constant. You also have to decide about words and vocabulary. The technical viewer gets annoyed when non-technical processes are dumbed down, but the non-technical viewer gets lost. Sometimes the presenter needs to work out what exactly people will want to know, what they probably already know and what they almost certainly need help with. With electric cars - the key thing people want to know is how long it takes. The answer depends on the type of outlet, the available current and the difference between the outlets. The trouble is as soon as you try to be technical and accurate and mention Amps - many will switch off. Writing the script is hard!
I'ma bit of a Landrover fan, and on Youtube is a load of videos by PowerfulUK ltd - who sell mail order parts, but the owner is very keen on making videos - of their parts being fitted but also Landrover's own parts being fitted. They're very watchable because of him - he's a bit eccentric, and NOT a know it all. he does his videos as a fan himself, and shows you the messes he gets into, how he fixes them and pretty much just pitches it right. He doesn't use technical terms that would confuse, and instead of the fancy words Landrover use, he'll call it a flap, or a clip-thingy, or other made up nonsense that everyone can understand. He does what we all do, prods buttons before reading the instructions where it says do not do this - and shows you when it's terminal or how to reset things. I leaned a great deal from his style of video. Lots of the bits he sells need modifications to the wiring because socket types get changed or fittings are modified - so he'll say "see this bit?" and point to a clip - you need to chop it off. You see him do it, and then see how it re-fixes. Stuff like that. If he did a charging video - he'd work out what people needed to know, then show them - he'd also point out how it can go wrong, and then show you how to fix it. He did an electric car one recently where he showed how you grab the cable from the boot, stuff it in the socket but look ...... the little light's not flashing - something's wrong - then explain that the car he's trying to charge has a slightly loose socket so you need to hook the cable over the flap, then the light flashes and you can come back in 6 hours. Then 6 hrs later he says how annoying - it still needs another hour? I wonder what the readout will say when it's an hours short - and he shows you. People see the impact of cutting a charge short. His videos are always hand held, often wobbly and often go wrong. He does things on the spur of the moment and occasionally breaks a plastic clip or something - so say - see this one? don't remove this one, because you don't need to and it breaks - very watchable style. A bit chaotic, but the guy really wants to help people. I'm not sure Tesla liked his video if him collecting his brand new car from a supermarket car park and spotting little things wrong with it, but I bet this helped people considering doing the same thing.
Making interesting tutorials on YouTube is not easy.
