You're right, I wasn't clear. What I'll do is post a 30 minute technical presentation on YouTube that I've given, but then slice it up into two minute clips for LinkedIn, change the aspect ratio to make it a square rather than a rectangle (it fills up more of the screen real estate on a person's phone that way), and add subtitles because I know mobile users often times watch videos without listening to the sound. Reposting other pieces of content you don't own won't get you anywhere, the copyright strike mechanism is crazy extreme. My friends who post guitar covers detune the song by a few percentage points in order to bypass the copyright strike filter, even though they're 1000% within fair use.
