Help with the video settings

Unfortunately, it can be very tough and expensive to try to prevent someone from copying videos that you put online. There are two main methods: DRM and/or Watermarking. Where watermarking is the simplest. You simply put a watermark on the video as you transcode it. DRM is a bit more complex, costs money and in the end, you still risk someone just copying it by using a screen recorder or similar methods. Just look at the amount of money Netflix and other companies are pouring into it and still, people are copying and sharing their content illegally.

Anyway, this is outside the scope of the WordPress plugins. I advise that you created a feature request issue in the Github repo or the h5p.org forums to help gather support for this.
