Hi,
I recently helped the French openSUSE community to edit simple video tutorial about openSUSE.
here the channel (using Yast2 and drawing and painting demo under openSUSE)
I am far far away from being professional but with the help and support of communities making this kind of video is not that hard (takes time yes) and it could be useful in my point of view, for new users.
As you can see from link, videos are short and made with a specific target.
-How to use … this particular soft
-How to install … softwares (for instance)
- Drawing / Painting (tools available)
etc …
So, what do you think about making videos about Ubuntu Mate ?
best regards
