Pal > Ntsc?

Does a progressive camera have any filtering at all or does it give you the full resolution? For example would the JVC HD100 actually give you the full 720 lines of resolution or due to many factors could it be something like 710 or 700?

Thomas,

Since the JVC HD100 has yet to be released, any comments on what it does or does not do would be pure speculation.

Based on my experience with other HD cameras, I suspect that the JVC will be filtered. And will likely have the option of enabling the full vertical resolution or leaving the image filtered, available in the menu system.

Both the 27F Varicam and F900 Cine-Alta are filtered with the option to enable full vertical resolution in the menus.

Great info, guys.

What is the vertical rez for a PAL DVX100A in Progressive mode??

I checked out that atlantis software. Works well, only problem is the price.

I'd buy it if I owned a PAL camera, but I'm only borrowing one. Anyone know of anything cheaper?

PAL Progressive is 576 lines of vertical resolution.

Thanks, Jon. So I guess for the ultra low budget filmmaker if they want best possible resolution for a film blowup (assuming their movie gets picked up) a DVX100A (or XL-2, etc.) PAL cam would be superior to an NTSC model.

However, looks like the HVX200 is going to change that. :)

I did find this interesting bit under "Will PAL Video help in the Video to Film Process?" on this page: http://www.vtpcorp.com/htm/vidfilm.htm

(It's talking about PAL interlaced) "PAL also increases the vertical resolution of the image since there are more scan lines used, although it has been said that for many reasons, progressive scan has a potentially bigger impact on the perception of spatial resolution, followed by horizontal resolution, and then vertical resolution."
