[Kevin Murray] “in other words, cameras use hardware algorithms to “fake” progressive DV50 but that interlacing is hardwired into the codec”
Panasonic cameras, DVX100, HVX200 and many others record TRUE progressive frames but they have to put them on interlaced tape with pull down (pA mode), when you capture this footage correctly and remove the pull down you have true progressive frames.
DV50 (or DV25) 23.98 is a progressive as long as it is on the computer there is never a need to introduce interlacing. You can also have true 30p if the camera supports it (if going to tape it is recorded with pulldown that must be removed but once captured correctly it is progressive as a file. Anytime you go to tape or video out to TV interlace is added by the video card or computer.
