Hi Michael!
Your uploaded project “hypetest” does not appear to be as described in your original post. I am not seeing the “vzarr” set-up - just an “.mp4” video.
The “vzaar” will be something You need to set-up - but in the mean time please review what @Daniel suggested as an over all approach - using a “rectangle” as a container for a video. Even though this tutorial is using audio - the same principles apply to video.
Here is information about embedding videos.
Note: I can open your Hype document & play it - I’m not sure what is giving @Casimiro the problem.
==========================
EDIT:
With a little more time I’ve created a Demo for You of using a “rectangle” to contain a video using the basic set-up in your “hypetest” example project above…
hypetestJHSv1.hype.zip (1.8 MB)
In the “InnerHTML” of the rectangle named “Video Holder” in this Demo we have a “video tag”:
<video width="800" id="myVideo">
<source src="${resourcesFolderName}/page4.ipodtouch.mp4" type="video/mp4">
</video>
Note: The id name “myVideo” is what is used for the “Play” & “Pause” javascript functions’ “id” - not Hype’s “Unique Element ID” in the “Identity Inspector”.
