Excellent interview. Thanks for sharing. Subscribed.
I'm imagining that 10 and 20 years from now people will be claiming to own one of the "taped box" Waterfords and the value will increase if they still have the taped box lol
Regarding the audio, a simple shotgun mic like the Rode VideoMicro will improve your interview audio a bunch. One step up would be a pair of lavalier mics, like the Rode Wireless Go II.
