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.

Well done Ella! I don't try to memorize the script... I make sure the script is just underneath my webcam so it looks like I have an amazing memory :)

<p>Next consider that mistakes can improve teaching. If you show your students that you also make mistakes, then you can improve their confidence.

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.

<p>If you don't mind skipping your own face, your easiest, cheapest option is probably PowerPoint itself.  PowerPoint allows you to record audio (and animations) for each slide, set up timing for the next slide to start automatically, and export the entire thing as a video.</p>

You are right, that's a good solution, except I do want to show my face. 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

@BenI. It's okay, but I was hoping for a program that answers requirement number 4 to minimize edit time. I often say the wrong word or sentence and I would really like the possibility to easily go a few seconds back and continue from there.

@EllaSharakanski i'm  afraid it doesn't. I suggest you record first, restart your sentences if you make mistakes and worry about editing later. One problem at a time. See other answers.

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).

sorry, totally missed this question @Ben. From what I recall I had to enable the Recording tab in Powerpoint. Under that tab there's a  Record Slide Show function, in there there's an option to turn on the webcam and show video preview.

I have created a PowerPoint presentation and I want to create a video of me presenting it. I'm looking for a software to make my life easier. The features I'm looking for are:

1. Can record a 25-minute video for free.
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.

For high-stakes presentations, I suggest writing a script. 1 page of well-spaced A4 reads back at ~3 minutes and allows you to get your points across clearly and concisely, especially points that need to be well-phrased.

This should enable you to do a one-take presentation on Zoom or OBS.

If you baulk at writing a presentation, record yourself, transcribe it (I think that’s built into Word on a Mac) then tidy it up. If you are like me, that will involve deleting many instances of the word “arm”.

[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.
