Adding custom metadata to scenes (or timecodes ranges) within a video

I have a use case where I want to break down a video into scenes and for each scene I want to add custom metadata. One example is, I want to add a locale to each scene (e.g. locales would be kitchen, street,  bar, hospital, office etc.). And I want this to be a specific list or a dropdown, not an open text field. 

I wan to add multiple custom fields like these, where it might be a single select list/dropdown or multi select. 

Does anyone know if I can do this or if there are any existing plugins that might help here?

If not, I am open to creating my own plugin to do this, but I haven't explored enough yet to know if this is feasible, possible. Any help on this would be appreciated as well.
