Same goes for e.g. car repair stuff and even some solutions people post to weird software issues. There are lots and lots of very niche videos posted by normal people who aren't professional "youtubers" and really just want to help someone out and document things they've done. Video quality, editing, etc. can be crappy, but the information within can be just what you need. Unfortunately there are also lots of absolute trash videos that sort of claim to show you what you need but in the end they don't. Same format. You can't tell which is which before you watch, unless you see that at least half of the thumbs are down in which case it's probably a trash video.
