HapYak is a flexible and extensible platform that allows you to create any interaction on top of your video. The Custom Widget Library is a set of more advanced interactions that you can add with one click to your HapYak projects (no need to hand code with HTML / JS / CSS).
Note that all custom annotations are in Beta and should be tested before going live.
Workflow
While editing a project, click the Add Iframe Icon.
