Yes, certainly. Depends on what you are trying to accomplish? for example:
- do you need Presenter Mode and see presenter notes, etc?
- does it need to be full screen? or will/would you use a Windowed (ie something other than full screen) Slide show video? (what I use)
- what else do you want to add to composited video?
generally not recommended (from what I've seen... not something I've dealt with) to embed video into PowerPoint, much better to have audio/video play direct in OBS, if practical
- are you planning to add a webcam view of yourself? or other overlays? or ??
search this forum for PowerPoint and you'll find a number of discussions. Just a heads up - the 2 most common use cases are teachers/educational type presentations, and the other is for House of Worship service bulletin content. An understanding of your use case will inform others who might make suggestions/comments
