Stop OD video recording

I just watched the video about managing urges in the stop OD program. I’m curious about the recording of the video. For the zooming in and out to your face during the video, was that done in the editing process after it was recorded or during the recording process? What software did you use for editing the video? Was it the same software as used for recording it? Did you use only your iPad/Mac/iPhone to record or some other gadgetry to record?
Thanks mama!
