Vertical video recording on laptop

[ashish531]

 I record my zoom on a macbook. I want to record my meeting in a vertical video so that it is mobile upload friendly. if required.  I want to know how can I do that as the meeting is recorded in the landscape mode or what are the other options to record zoom meeting in a vertical mode. Please let me know. Thx
