Don't know about videos but...prepositions are just tricky. Because there are almost never 1-to-1 translations for them, it's actually easier to just learn 1. which situations to use them in and 2. which verbs to use which prepositions with. Because the thing is, even if you learn like all 8 or so possible translations for "auf" (it's close to around that many, no joke) you can't apply the possible meanings of it just wherever and whenever you want to. Like it can mean "on," but you can't use it to mean "on" everywhere because of the fact that multiple other prepositions can also mean "on." It really is something, which is, for the most part, arbitrary, that you just have to learn over time as opposed to something you can easily conceptualize like you can with grammar.
#Any good videos to start to teach me prepositions?

Like if you type in "on" and "auf" into dict.cc these are the results you get:
I have been learning German for almost 7 years and I think after all this time, I do instinctively know when to use what, but there are still times where I am not 100% sure. Prepositions are just really, really tricky, and sadly not a very black-and-white concept.
The best someone could do is give you a video about common and useful verbs in which the prepositions for them are also discussed, but really, it's not like you can learn one preposition and just be done with it; there always seems to be something else you can do with it that you stumble across.
I mean, eventually you do learn it all, but only after having eventually discovered all of their uses...not after memorizing them in one day.
The things in language that are largely arbitrary are often the most difficult things to learn. It's a matter of exposure and repetition with them.

There are a few different things you can learn about prepositions. Cursed Alien gave an overview of how to learn the meanings, but maybe you wanted to learn something else? For example, which case goes with which preposition? There are some songs and other similar memory techniques that some people like to use for that.
Here is a link which describes some basic rules of some of the simpler preposition usages: https://resources.german.lsa.umich.edu/grammatik/prepositions/
There are quite a few videos about prepositions on YouTube if you just search it. But for an example of songs for memorizing cases, here is an example: https://www.youtube.com/watch?v=X2MoLSJxt6A
