Answers.Text: Good idea, but as a non-native English speaker, even when I write a script or memorize everything, I still make silly pronunciation mistakes and sometimes get stuck in saying a word. Anyway, in the end, after many many rehearsals, I just recorded a single take presentation as you suggested, and yes it is not perfect but I guess I'm okay with that.

Answers.Text: Thank you, but my presentation is for a well-known computer science conference and it's about theoretical computer science, so I don't think I should add any mistakes. Usually those lectures are with an audience, but because of the virus it will be pre-recorded. So it's not like a movie, it is more like a ted lecture, which is usually a single take.

Regarding products that are free and show a video of me + the screen, there is zoom (you can start a conversation with yourself, share the screen and record), and also you can use the built-in "screenshots" program, and from there you can put your face on the screen and record the screen

Answers.Text: Powerpoint can also show your face in a window in the corner. Recording slide by slide allows you to easily redo a single slide without having to redo the whole thing. Can also reorder after recording, or divide the presentation into smaller chunks if needs be, before exporting to video. As much as I'd prefer the idea of doing my presentations in a more "techy" way with latex or markdown, PowerPoint is just providing such an efficient way to record video presentations that I'm sticking with it. It also allows you to publish directly to Stream, if you're institute is using that (in Office365).

  2. Works on Mac.
  3. Can record the screen and me (audio+video).
  4. Lets me rewind while recording and continue from there, so that if I make a tiny mistake I can just go a few seconds (or one slide) back and continue recording.
  
  Any suggestions would be greatly appreciated.

  [OBS Studio](https://obsproject.com/) fills your description.
  
  It is not the easiest program to use, but you can find plenty of tutorials on YouTube.
  
  While rewinding the recording again might seem appealing, it is very common to find out more errors *after* you complete the recording. In that case, you need a better video editor. OBS studio might be enough, but [shotcut](https://www.shotcut.org/) is your best bet.
