Interactive Video

I want to customize the ui of https://github.com/h5p/h5p-editor-interactive-video Component

I've run the command

h5p get  h5p-editor-interactive-video

which downloaded the main component and all its dependencies

Now I Want to edit h5p-editor-interactive-video  js files and rebuild it and get .h5p file by  renaming the .zip file of current directory

Problems i get

1.How to create a content for it

2.how to create h5p.json content

I am not sure if this is a bug or not.

 have a background video that is stored on Vimeo and a H5P interactive video project that contains hotspots. When a hotspot is clicked that is linked to another time in the video some of the intermittent screens are displayed before the actual target is displayed.

What is causing this effect? Is there a setting that might prevent this? 

I want to prequalify a pull request related to the following:

As an author I want to be able to direct the user to a specific time in an interactive video based on the answer they give to a question I've given them.
