Mitch from The Audio Dabbler has produced a tutorial series on how to produce tutorial serieses... Serii? Nope, I checked, the plural for series is series. Fuck me, English is weird.
The two videos in the series focus on different recording methods. The first method is computer aided, but for Maximum Meta there is also a video on doing the whole thing using only iOS devices and apps. I've embedded the iOS video here, which has a supplemental video showing off the results.
Here I demo how I filmed and edited a tutorial using only my iOS devices.
