So, I'm refining my talk with a draft that contains an intro, main development, and conclusion. Also, I recorded myself speaking a short introduction (less than 2 minutes) and it was terrifying!
For the next and final step, I'd like some tips to record my presentation, I'd like to use a presentation and a webcam and my first thought was about using Google Meet for it but the record option now is just for premium users. Any tips? I'm afraid I can't deliver the best audio for the presentation too.
