I noticed on the Interactive Video that it is possible to set seek times as an consequential action / response to a right or wrong answer.
This sounds like the basis for Scenario Branching.
Is Scenario Branching possible in H5P IV ?
Although the seek option might be developed to include a hyperlink to another short video clip, this would involve a series of short videoclips stored elsewhere and accessed via static links that get easily broken if the site structure gets moved or updated.
Ideally all the related video clibs would be embedded and linked within the same 'entity' for Drupal CMS connectivity and referencing purposes.
Rapt Media for example I believe have this kind of scenario branching capability and UDUT2 also has a powerpoint / presentation slide based version of it. However, can any of these be imported in to H5P or does it have to presented as a completely separate lesson entity?
