I am trying to create an image of the page.
If I try to print or export PDF from safari I only get part of the page.
If I choose export from Hype the youtube images just show as blank images.
You could probably use an add on for the browsers. E.g Chrome and Firefox I know have screen capture for entire web pages. “Fireshot” is quite a good one. Available for both. Not sure about Safari.
In Safari if you Export as PDF (rather than print) you get the whole page with images too.
I also had a problem with Paparazzi. I went to the Chrome Store yesterday to check out screen shot extensions and I found one called “Open ScreenShot” - here.
I’ve only used it to capture your page demo target - no problem. It’s received high ratings & it’s free.
If the entire page happens to be an entire Hype document, you could use the File > Export as Move > PNG Sequence… and then just export a single frame (timecode like 00:00.01).
