easiest for editing IMHO, is a second camera on a wider shot of the interviewee and interviewer, or just a different angle (as other people have mentioned close up on face/ skewed shot….)
run this with onboard mic, and keep both cameras running,
if you dont have budget for a good second camera then just use a cheap dv camera. tint it , turn it B&W, add noise etc. in your edit.
you only ‘need’ this shot to cover the jump edits, but can drop it in just to keep ‘interest’.
b roll is best but we all know that there isnt any footage of the new product they’re talking about, they dont have images of the new staff about to join the company or whatever else…
it makes the interviewee more at ease coz they only have to go through the questions correctly the once.
it makes your job easier coz you dont ‘have’ to try and cut two (or more) differently worded takes on the same answer.
the interviewee runs through until they’ve got decent takes for each question (1 or 2 fluffs/takes per answer) then they can go,
next shoot the questions close in on the interviewer.
job done
yes its not the best way but it gets it done, quickly and gives you options.
