No 480 24p? at DVinfo.net

Paul Pelalas · February 17th, 2006, 10:12 PM

I was reading the recording formats of the camera as I am about to purchase one, and according to the specs it does 480i 60 (23.98), but no 480 progressive like the the DVX ? http://pro.jvc.com/pro/attributes/HD...-hd100_faq.pdf
I hope that's not true as I still need to shoot in SD and don' want to lose the ability to record sd progressive.

It is capable of recording in DV24P and DV24PA (different type of pulldown, same options as the DVX100). Perhaps Tim or Steve could explain exactly which mode and frame rates it's using in which setting, pretty please?

unless i'm mistaking, and i could be, the dvx shoots 24p and 24pa over an interlaced signal. so if you notice that when you shoot 480/60 it is actually 480/60i, an interlaced signal. so somehow the 24p modes are shot as progressive over an interlaced signal. well low and behold the jvc shoots the same way. however, the jvc shoots 480/60p intertwined with hdv. don't ask me how they do this but they do. so what this means to me is that the jvc shoots the same as the dvx but with 16:9 chips and better glass. if i'm wrong somebody please correct me.

That pretty much sums it up. For all intents and purposes, the HD100 functions exactly like the DVX100 when in DV mode. Actually, it would be more accurate to compare it to the XL2, since it shoots true 16x9 instead of stretch.

It's confusing because though it can can be seen as progressive being overlayed on interlace, it still is a progressive picture, not interlaced. I thought when progressive was recorded to tape, it applies a pulldown, and those pull down frames are also progressive frames, which can be removed to extract the original 24, so it's not interlaced.
On the HD 100, when you shoot 4x3 480i , is there wasted resolution because you are using less of the chip for a 4x3 crop . I mean compared to say a DVX or other sd cam, which would give you the best 4x3 and why?
