Merging vaams means that you can combine two vaams, often one generic and one personal. A generic vaam is a longer one where you do your pitch, your sales demo, your tutorial, etc. A personal vaam is shorter and custom to the person you send it to. That means that you can send a well-rehearsed and put-together vaam to anyone, with just a few seconds recording and a few seconds to share it. No more retakes because you messed up the ending. No more recording the same content over and over. Just record, merge and send.
