General help

There is a plugin called Readspeaker that may be worth looking into. It's a paid plugin so that might not suit your needs though:

Most modern browsers come with 'speaking' built in. For free.

What I seek is that every text I add in Admin should be combined with video too
Such as:
Course name should be in text and video
Course description also be in text and video
Course questions, answers, choices should be in text and video
and all items in the course should be in text and video
What is available now in Moodle as I found is adding them in text only

Every added text should have a button beside it to point to a video to be working after clicking on it

Or every added text (including course name and all other course structure) should be added in html5 containing both text and a button points to a video on youtube for example
Any suggestions in this?

This is possible.

The idea would be to append something like ##[youtube id] after each of those locations. And have a little javascript in the footer of the page, that would look for those snippets and turn them into triggers for youtube lightbox players. In the following example we use a thumbnail as a youtube lightbox trigger. But you could use a little icon just as easily
eg https://demo.poodll.com/mod/page/view.php?id=184

I suspect that not all those locations can be filtered using Moodle's filter system. But if they can it would be reasonably simple task. Since the functionality could all be captured in a single template for Generico filter. But you could still do it with plain old javascript in the additional html area of Moodle. 

Hi all,

Maybe this is a bit of a silly suggestion, but I've seen it implemented in some Moodle sites for providing video tutorials.

Create a site level (or course level) glossary
Add items to the glossary, pointing to the specifics of your course, etc...
Add a video in the item description bit
Turn Glossary Item auto linking on

Once done, you're set up with a set of interactive popups your users can click on whenever they need to find something or need to learn about this.

If the glossary itself shouldn't be consulted, but its items should, consider turning on stealth mode (available from 3.5) and set the glossary to hidden but available.
