Panopto allows its users to combine powerpoint slides and video screening at once. After recording your video, you can upload it to the Panopto system easily, and then edit the video if you need to cut parts. For instructors at universities using learning management systems to organize their course materials such as Desire to Learn (D2L), Panopto allows the users to embed the videos quickly to the D2L platform, which is very convenient.
The editing section is not that easy to use. It is slow, and it does not allow you to combine two videos you recorded. You need to record everything in one video and start cutting that. It also does not allow you to add images or texts to your video. It is not possible to edit voice and video separately, either; although Panopto allows you to the voice recording only.
I am preparing lecture videos using Panopto for my online classes. I usually choose powerpoint screening and audio recording options, which allows me to read the printed text I have while recording the audio, and change powerpoint slides by hand while recording my audio.
Note: I recently figured Powerpoint can also be used for creating videos. Powerpoint takes time to learn how to combine videos, powerpoint slides, images and audio recordings but gives wider options. Therefore I usually prefer Panopto for videos I will publish for my online courses because it is way more convenient to use. But, if I am recording a video to advertise my class via my own webpage, then, to make it look "prettier", I switch to Powerpoint (technically because I did not invest my time on learning how to use Premiere Pro CC for professional video and film editing).
