Hi @schuemie,
This is really great idea.
Not all of users can understand principles and features of some the OHDSI tools (for ex: General questions on Atlas)
In my experience such series of short tutorials will be quite useful -at this moment new user should have a lot of patience and coffee to reach his needs searching across documentation and looking through hours of videos.
Your video seems perfect! 
I suppose that sequence of themes should be approximately like this:
- Vocabulary and OMOP CDM shortcuts (focus on definitions of domains)
- ATLAS: Concept Set definitions (regarding previous theme- new users often mix different domains in the concept set)
- ATLAS: Cohort building (explaining start/end date, qualifying criteria etc.)
- Population level estimation method (idea of propensity score is exotic for newbies)
- Patient level Prediction
- ATLAS: Estimation
-…(continue/edit the list)
