Here is how to embed the HD version of a video into our tour
To embed the HD version of the video, when you generate the embed code, you need to make sure you have the BLUE HD option clicked and blue, then generate the code and paste into the custom video section on Edit Details of your order. If you do not, then it defaults to the non-HD version. The size does not matter as we automatically adjust the size to fit the window allocated in the tour.
YouTube has a similar option to embed the HD video.
