Adding Quiz Questions while Watching a Video

Put all your instructions and folderol on a slide. When the learner is ready, have them take an action (like click) which advances to the next slide with the video. If the video starts when the slide timeline starts, you can use the slide timeline to control what happens.

So when the timeline reaches the appointed moment, pause the timeline, show layers with the questions and feedback. When that is done, hide those layers and resume the timeline until the next question.

Two things of which you must beware:

1. If you allow the learner to have video controls, they will use them, and throw off your timing. It is a trade off between you having control, and the learner having control, but since you want to stop the video, and you know when you want to stop it, it seems to me to be an easy decision.

2. If you allow the learner to click on the video, it will stop and throw off your timing.  Avoid this by covering the video with a shape that is filled, without outline, and set to 98% transparency.
