I decided to attempt to make a video about some experiments with Scaler sequences, and to use a combination of OBS studio https://obsproject.com/ and Openshot https://www.openshot.org/ to do so. Having had a few initial struggles, I thought it may be worth sharing the following.
After some frustration it became clear from web forums that OBS did not respond to normal ASIO interfaces. In my case dropping back to MME was not an option because the manufacturer of my PC had disabled the Realtek audio on the motherboard.
However I found (all hail Google !) GitHub - Andersama/obs-asio: ASIO plugin for OBS-Studio which were asio drivers for (as its name implies), err OBS.
So after installing this driver, all that was necessary was to go to ‘Sources’ in OBS, right click and add ‘ASIO Input Capture’
In my case, my MOTU interface has a hardware loopback feature, so in OBS settings the Mic/Auxiliary Audio should be set to input from the DAW. (if you don’t have loopback, a virtual cable like ‘VAC’ might be needed.)
The input meter then shows up in the ‘Audio Mixer’ section, and picks everything up from (in my case) Live.
I am not attempting to narrate live in parallel with recording the Live screen and sounds - that seems like a formula for 25 takes. Rather, I’ll record it with a Shure Mic via the MOTU into (probably) Adobe Audition, and then use Openshot to overdub it all together - there isn’t much of a synch problem with the narrative.
