Which camera to rent for a video shoot occurring at night outdoors with very low light?

I will be filming skydivers doing a jump at night [so, speeds between 20-40 mph when they're going past me and I track them] wearing suits with lights on them. I would like to rent a DSLR that shoots video so that I don't have to carry a video camera and a DSLR to shoot both during the day and night, are there any Nikons that can shoot video in the dark? I'm renting from these guys, as they are local.http://kspphoto.com/rental-department.html
If you could tell me off their list which to rent, and if there's no good Nikon DSLR to shoot night video on recommend a video camera to shoot with.

Sorry but you can't do "filming" with a video camera… You can shoot video but these cameras don't use film.

None… There are no cameras that shoot in very low light - they don't exist. In Hollywood movies they always appear dark but if you were actually there you'd be amazed at how much light they use.

Low light camcorders, Sony leads the list. The following models all got excellent for low light picture quality.
Sony HDR-TD20V
Sony HDR-PJ710V
Sony HDR-PJ580V
Sony HDR-CX580V
Canon VIXIA HF M52
Canon VIXIA HF M50
Sony HDR-GW77V

No DSLR got an excellent rating for their video, much less low light video.
