Answer 1

Andrew Warner at mixergy.com once answered someone who asked this question. He said:

The picture-in-picture layout is from Skype. The new format is from Ecamm, a new recorder.

I suppose the recorder is Call Recorder from Ecamm.

Answer 2

I use:

Call Recorder - to record

ScreenFlow - to edit
