I have a question.
I was watching "Collateral". Michael Mann said it was mostly shot on digital video. I notice when objects, like cars (mostly wheels) or street light poles pass in the shot, frame by frame, they are represented in a cluster of that object. 4-5 light poles evenly spaced, blending in together.
Why is this?
Shooting in 24P, regardless of shutter speed, there should only be 24 (23.98) shots in a second. Each frame exposed just once.
Right?
Why the appearance of multiple exposures in a single frame?
Doesn't seem to be a long duration exposure smear. Multiple separate exposures.
This (if I remember correctly) is present in "Miami Vice". And some night footage of some reality shows, I assume shot in 60i. My Z7U may do it too, I just haven't used it under those conditions to notice.
I don't think it is only in night time footage, but in footage of the city at night, it really jumps out at you.
What am I missing?
