vx2000 progressive question

i'm trying to understand how progressive images are handled in a workflow.
right now i'm dealing with a vx2000 and am curioyus as to how its frames are
stored on tape. the reason i ask is that i know that 24p images in the dvx100
are captured as progressive but broken down into fields when they are sent to
tape. is this kind of thing done with the 2000 in progressive mode? i'm assuming
that 30p will be significantly different because of the lack of extra frames. all of this
assumes ntsc work, of course.

i want to bring the 30p into final cut or premiere pro. i'll be editing with an ntsc
monitor for previewing. somewhere in this chain, i know the 30p will have to
be dealt with as lower rez fields.

where does this happen?
is it done by the camera internally?
is there a process the video has to go through during or after capture?
is it handled by the editing software?
what is the pattern?

any help is appreciated. thanks,

george

The VX2000 is not doing a real progressive video.
The progressive option is a joke that is not giving you usable video.

That isn't true. The VX-2000 shoots real progressive, but it isn't in a format which is terribly useful. It is 15 frames per second which will produce a strobing image. You cannot shoot 30p, 25p or 24p with the VX-2000.

There are some good uses however. You can use it like a continuous motor drive still camera that captures 15 pictures each second. The only limitation is the 720x480 resolution. Another good use would be time lapse video where you want to speed it up in post. For example, you can film the sky in progressive mode and then speed it up perhaps 10x in post to see rapidly moving clouds. Or you could shoot a sunset and speed it up to happen in 10 seconds.

But the VX-2000 progressive mode won't help you get a "film look" if that's what you want.
