Interviews are being shot standard-def, the subject matter (loosely) is “webcams” so the quality doesn’t need to be great here (the idea of up-rezing a 320×240 seemed overkill).
However, yes, capturing the screen at a standard-def size seems absurd, so I guess I’ll go with this… it’s just mixing matching and mashing formats that’s a bit of a put-off to me.
Thanks for your replies, Shane
