An example of a Q-Review recording.
Here is an example of a Q-Review recording:

Normally, the left hand screen shows the lecturer and the right hand screen shows the presentation or whatever you currently have on the computer, however you can also choose to use a visualiser instead or to only show the presentation and not yourself too.
Remember: whatever you currently have on your computer screen will appear on the recording, so please be mindful of showing emails or other confidential items, e.g. a student's personal information.
