Thanks for sharing your process and enjoyment, John 😀
Yea, the main recommended way is to share a youtube link, as you did.
A guide on this process can be found under the ‘Support’ tab, and the ‘How to use FiddleHed’ page. Part way down this page, there is the question ‘How can I upload a video to the site?’. This provides good info for folks navigating creating a youtube video for sharing. Here’s the reference page for this: https://fiddlehed.com/contact-help-new/how-to-use-fiddlehed/
I’m not as familiar with the .mov attachment sharing, though am seeing the 50 MB limit prompt.
I’ll investigate this more and share what I find out.
