I agree with Lisa. You’re better off stepping down your pics in post, rather than trying to step up later.

With shutter speeds, you’d need something quite high for motorsport. However, big question is are the races run at night or during the day? Ramping up your shutter speed will cause your depth of field to shrink considerably, throwing out your focus very noticably as the cars come towards you.

I’ve shot cycling races (Much slower, I know!) as an ENG cameraman using 1/125 shutter, which made everything appear sharper and that beautiful clear frame look for slow motion replays. However, our cameras were dodgy as hell, and I figure since you’re shooting in HD, you’ll have a lot more options. I’d recommend shooting some traffic on a highway with different shutter speeds, and see what works best for your equipment. Though I think it’d have to be something higher than 1/250.

Good luck 🙂
