I'm not 100% sure if I understood the problem right, but maybe OBS [1] could be an easier solution. You can use it to record screens and webcam streams. You can layout "scenes" with the video sources and use it while holding to lecture to switch between webcam and screencast. It's usually used for livestreams of all kinds, but works for recording as well. With my little experience in video editing, I'd say 30-45 min for a whole lecture is very optimistic, so maybe this would be an easier solution. [1] https://obsproject.com/ https://obsproject.com/

Thanks for sharing this! Can you simultaneously record your screen and your face, and then later splice the two together (while keeping audio synced, preferably)? To clarify, basically the desire is to be able to sit in front of a computer, look through slides while talking to the camera, and then afterward go through and (easily) choose which segments should show the screen and which should show your face. And hopefully the audio would just auto-sync, so you don't have to fiddle with it to get the lips to line up when it's set to show your face.

  If you already have powerpoint, try that. Camtasia is a licenced ($300) tool, but has almost fool proof editing and post production

  You can't use it to record into seperate files. However, you can use it to make the necessary editing while recording the presentation. In OBS you can create Scenes with multiple video sources. The scene will be the output you see in the video file. You can add the video sources as layers into the scene, scale and move them around. So you could create a scene where the main focus is on the PowerPoint slides and the webcam is just in the corner. The other scene would be the other way around. Then, while recording, you can switch between the scenes to show the powerpoint or the webcam. This does not allow for as much flexibility in post, but it would save a lot of time since you don't have to edit the video afterwards. Also, the audio should be in sync as well.

  I do exactly this. OBS is, in my opinion, what you want. It's worth learning for this problem alone. In short: get OBS installed and started. Then add the web cam as a camera source to the default scene. Then load up PowerPoint, Google Slides, whatever, and add that window as a "Windows Source". Make sure the web camera is above the "Window Source" in the list of sources - they're like layers on a cake. You can edit the web camera source in the live preview to then be a box in one of the lower corners (this is called picture-in-picture). I recommend crafting the slides to support having a picture-in-picture setup. Here's a (very large, sorry) example lecture I did for Chester University in England: https://drive.google.com/open?id=1xT31CU8Lfob88FxaDXAVWy-uXCNjNIQ4 https://drive.google.com/open?id=1xT31CU8Lfob88FxaDXAVWy-uXC... -- skip to about 3-4 minutes in to see how I'm presenting the slides, then jump to about 22m in to see how I present a terminal for programming needs. Reach out and let me know if I can help you or your wife with this. I'm keen to help anyone having to go remote for this sort of thing.

  I made a video that describes the setup that you're looking for to help my own department get set up with OBS, you're welcome to check it out here if you're interested: https://www.youtube.com/watch?v=uNFiBVWhWYI https://www.youtube.com/watch?v=uNFiBVWhWYI
