Without getting my pedantic head on, I’m just querying this because I am genuinely interested. The camera itself does store the progressive frame within an interlaced video signal by storing the lines in a certain field order. Would it not be wise to maintain the correct field dominance that the signal started with?
Or a better version of the question is, what problems might you encounter (if any) if you don’t maintain the field dominance of a progressive frame encoded within an interlaced signal?
