The two things with live video:
1) Video work is difficult. Interesting video work is even more difficult. We’re used to well-edited, well-paced video — that doesn’t happen “live”.
2) Mobile data connections are often terrible. Live videos are fraught with breaks, jumps, and drops, and that’s inherent to the mechanism.
On the positive, attractive, charismatic people with an extroverted streak do well in live video. But they’d do well in any form of video!
