Should all of my livestream be live? Or should I integrate pre-recorded content?

Do you want it to be perfect or do you want it to be real?

If you need to really control the brand, then you should fully pre-record, and then keep the interaction with users via the hosting platform, that can allow for chats, Q&A, or even sidebar rooms. But if you want it to feel “real”, with less concern for brand control, then stay as live as possible. You can’t have it both ways - unless you are willing to put in hours into rehearsals - so be clear with your objectives to set clear expectations with your production team.
