Hello Peter,
Click the RED colored record button in the initial screen which you have shared with us.
Once clicked, application will start to capture your screen and also the camera.
Then type "Shift - End" on keyboard to end recording.
Once done, video editing screen opens, click bottom left icon to open the branding options.
Hope this helps.
Regards,
Mukul
Thanks Mukul,
I will give it a try.
Is there also some magic for importing video that has been recorded previously? I don't seem to be able to find the import button as indicated below.... 
When I try to import a video with the import button mor eto the right on the ribbon,I can only make it run during the slide on which it has been imported. Not expand and sync it to the whole presentation.
thanks for the support...
Kind regards,
Peter
You use the name "theme" to describe two completely different things: the MP4 that plays before and after a presentation's content, and for the elements of the layout of the slides used in the presentation. This causes confusion.
Referring to the former usage -- the video/audio that introduces and ends a presentation -- if I scroll to the bottom of the list and select More themes, I am taken to a download dialog for Adobe_Presenter_Assets.zip. If I select Download and wait a while, a file by the same name appears in my Downloads folder. What, praytell, do I do then? There is no description of adding Presenter assets in the skimpy and incomplete help document. After a couple of hours of fruitless labor this afternoon, I gave up trying to install these "assets."
Some of my time was devoted to unzipping the file, but I just was forced to guess at at its intended location. The unzipped files content included a few dozen files whose names were long strings of characters without extensions. Are you bewildering us on purpose?? No matter where I placed these files and folders, I had no access to any additional "Presenter assets."
Requesting an explanation here of how to get "more Themes) is my last recourse.
