If you are using videos that are hosted online, there is software that you can use to embed that video and then insert pauses, questions, or your own text. Many of these can be exported as SCORM packages or imported into some LMS's.
One of the newest is H5P which you can check out for free. Here is an example of one I made to check it out. The video was made by someone else. H5P can be installed on a few LMS's. The site where that is hosted is more for trial/testing.

Another product that can do it is EXElearning. It is a free download and can use existing videos online or you can use your own. It allows packaging the content to SCORM, xApi and a few others including standalone HTML files.
I hope this helps and have a great day!
