Thanks for your reply!
The lesser dimension on 4k is 2160, correct? I see how you could still crop HD out of that though. So I guess my assumption that filming in 4k for Instagram vids won't increase video quality so it's fine to just shoot in HD?
A general question about resolution. I posted this on r/videography and got zero responses. Maybe my question(s) is too hard, or too stupid? I don't know lol.
Does 4K make a difference for Instagram Reels?
Technical/Equipment Help and Information
The max resolution for Instagram Reels is 1080...
