Do you have support for how-to's to create the mixing and adding in the video of ensemble numbers of online show The Big One-Oh?

Hi Kari!  Thanks for asking this important question as we forge into putting on shows in the world ahead.  When you order your Showkit for the online edition of The Big One Oh!, it will include a Director's Guide explaining all the basics of putting up an online musical-music, choreographing and directing. There will additionally be an online tutorial presented by iTheatrics, 5/16/20 & 5/17/20, 1-3 EST. This will include the ins and out of rehearsing and presenting a musical with  students that are not in the same room. There is a pre-registration and limited number of participants.

Information for music and video editing and choice and use of various platforms is your personal preference.  Congrats on bringing this to your students and break a leg on this new layer of musical theater!
