I thought you would just click on the Resources drop down and get Tutorials/video tutorials but no. In fact I only came across them by accident and forget how I did that!
You are dead right. When I first loaded up Kdenlive, this magnificent editor opened in front of me and I just starred at it, wandered around the menus a little and thought, now what? Help was absolutely no help. Found this Forum but everything they were talking about, at that time, was like a foreign language. A few hours on the web helped.
There must be more.
On the Home page, from page 4 there are some nice little tutorials explaining new features. Click on the read more tag.
Searching for "Kdenlive" on youtube & co also brings up some useful tutorial clips.
