Interactive Video

I would like to create an interactive video using a video from youtube. However I don't want to use / show the entire video. How can I make the video stop and end at a certain point?

How do I get rid of the Questions Answered star at the end of an interactive video? We don't need it.

Thanks

There appears to be a problem with the "save content state" feature of H5P and the saving of user's responses to questions embedded in Interactive Video. When partially completing a video and then returning to it, only the user's progress or timestamp in the video is saved -- their responses (whether submitted via the "submit screen" or not) are not saved. In fact, even if the user returns to specific questions they've answered already to answer them again, the submit screen does not seem to accurately record their new answer or updated their score.
