Late answer, I know. At the moment this possibility seems that has not been directly-implemented.
You may give it a look to the impress video converter extension.
Command line with
You can export the
jpg, whatever..., and then convert the result in a video. (You may need imagemagick).
Assuming you have installed on your system the right codecs (libx264 or better, I refer here explicitly to the encoding libraries) and that the images are named
you can use a command line similar to the following one:
ffmpeg -r 1/10 -i picture-%01d.png -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4
-c:v libx264 : Output video codec (i.e h264) but if you have h265 is better.
-r 1/10 : Display each image for 10 seconds.
-r 30 : framerate of output video.
-pix_fmt yuv420p : Output video resolution (not really needed)
There are tons of options. Moreover, with
ffmpeg it is also possible to add audio tracks to a video.
For example to add the audio of the file
input.mp3 you can use:
ffmpeg -i video.mp4 -i input.mp3 -c copy -map 0:v:0 -map 1:a:0 output.mp4
Again there are tons of options (you can compact in only one command line, stretch the audio ...)
Bonus: the following line will shorten of 20% a video and audio (note atempo=1.25 is
1./0.80 where 0.80 is the compressing ratio for video -- useless complication but it works in this way).
ffmpeg -i output.mp4 -filter_complex "[0:v]setpts=0.8*PTS[v];[0:a]atempo=1.25[a]" -map "[v]" -map "[a]" output_02.mp4
Video Editing Programs
As you see this is a path that may lead to use video editing programs such as
You can use a Screen Recorder (also know as screencast programs) as suggested from the other answer.

Video conferencing software
There is a wide number of Video conferencing software that allows to share your screen, add your audio and record the session. Pick one.

The World WIDE Web
A good number of sites offer for free and online the possibility to convert a powerpoint to mp4. A simple search on your preferred search engine will show you a bunch of them... and all your intentions of confidentiality and privacy may RIP.

zip and you extract with its subfolders, you will be able to find the media included, original audio files too, and to use these to build your video.
