Get an Amazon Fire Stick. It gives you much finer control over the "sampling" fast forward and back.
Is that free, and how is it used on a computer with, say, the videos referenced here?
My only experience with Amazon Prime is on a "smart" tv. There the fast forward is braindead to the point of dissuading me from using Amazon Prime; Netflix, OTOH, is perfectly usable.
With Amazon, to skip forward and stop you have to press buttons XYXZX. To zoom forward you press XYXXZX. If you are concentrating on what's on the screen then the tendency is to leave your finger on that second X, rather than
preparing to stop at some time in the future by pressing Z. The, if I come to a bit that looks interesting, I instinctively press the button (X) and zoom forward. Getting back to the possibly interesting point is an exercise in frustration.
GUI usability? No problem; the designers can use it just fine.
A lot of Carlson's videos deal with vacuum tube (valve) equipment. Now to old bastards like you and I we already know that theory and have experience with it. But think of all the young EXPERIENCED engineers/techs who won't know a 6AL5 from a 12AX7 because they never worked with it. So the detail we find snoozing. So should Paul premise his videos by saying "you old bastards are gonna be bored" vs "you young guys be careful because this stuff will bite". He correctly assumes the later and you and I can decide if we want to watch it.
Curiously, I know little about valves. Since I've now got a partially working Tek 184 which multiplies a 10MHz crystal output to 20MHz, 40MHz, 100MHz, 200MHz, 500MHz, I'm going through the pain of how 7487 nuvistors are enabled/disabled in the context of "random" tweakable inductors and "parasitic" couplings. Using 3 transistors (plus caps and resistors) to divide a period by 5 is comparatively obvious
Ideally Carlson (to unfairly continue your example) would state something like "this video takes you through the basics of X, and will be of interest to people that don't know the difference between a 6AL5 and a 12AX7". Or something.
