Honestly the biggest hurdles are the mythical free time and being comfortable enough with my understanding of the material to allocate said free time. I love the Khan Academy-style super casual, not overly produced, just "here's me writing out the concept and providing a worked example". Take a look at the link in my profile, you'll see its mostly that and talking head over code/slides recorded on OBS. I like that style because it requires minimal overhead work on my behalf.

Students' attention is low (not an insult, just what my analytics show). They are mostly searching for a fix to their immediate problem when coding. So my videos are split into 3-10 minute chunks covering that single thing. Recordings for a single concept take roughly 1ish hour, mostly a combination of setup, being human and flubbing words, and something in my examples going awry and taking too much time on it rather than demonstrating the example. I mostly record on Sundays (again, free day) or at night if I know I'm going to be away. As faculty, you're not paid extra to do this, so its very much intrinsic altruistic volunteering your time to do it.

And like I said, the second part is being comfortable enough with the material to record it. I'm teaching Intro to AI for the 3rd time this semester and while I'm confident in my ability to teach it, I still have some kinks in my examples. Typos, what gets covered when, etc. type things. I feel ready to record it during my next iteration, but then we fall back to making time to do it.
