When Keynote is in play:
- slides can only be displayed full screen
- Keynote window is unable to be resized when in Play
- all other applications are hidden, including the output from the camera therefore a picture in picture recording is not possible.
A workaround to record the camera picture and a reduced size Keynote, is not to Play the presentation, but show Keynote in "Edit" mode as follows:
resize the Keynote window to an appropriate size
remove the navigator and inspector panels at each side to maximise the slide window
View> Inspector > Hide Inspector
View > Slide Only
View > Hide Toolbar
Advancing through the slides is made by using the page down keyboard key
no animations will display as they can only run in play mode.
Record the picture in picture using QuickTime using: File > New Screen Recording
