i would only go for a dedicated video camera if you are intending doing LOTS of video work - if only a bit now and then, i would go for a bridge stills camera with video function. if you do go for a proper video camera, i would get one with a HDD in it for easy storage and transfer to pc.

if it's car related, i would go for a bullet cam and a HDD recorder. bullet cams work surprisingly well at low light

my fuji s6500fd does very good video and unlike a lot of other stills cameras that do video, the zoom lense can be used during filming.
