Traditional 24p is recorded into 60i as either 24p or 24pA. I'm only guessing but I assume 24PsF means Single Frame. Their new HDCAM SRW can I believe record 60 disctrete frames per second or 24 discrete frames per second to tape, this avoids having to de-interlace and remove pulldown in post. Given the huge data rates involved in recording HD at low compression ratios this makes a lot of sense.

Price of the camera head is rather attractive, just don't forget about that 'optional accessory', the lens.

24PsF means "segmented frame". It means that he image gets segmented into fields and recorded on tape as two fields. IINM, the original Sony CineAlta (which is the first camera to employ psf notation, is it not?) would use basically PAL mode, 50i, but run the tape just a little bit slower so it was recording 48 fields to tape. The 24p frame was segmented into two fields, so 24 frames = 48 fields. It's not PAL, it's not a pure progressive frame, so they called it "segmented frame".

In the end it means nothing -- the image on tape can be easily reconstructed into the original pure 24p frame sequence.

How are the 24P frames stored on a DVX100 tape? Isn't it say odd field lines first, then even field lines.

Is there such a thing as pure progressive frames in any video format?

As I become more and more dependent on post work, I am really looking forward to a future video format that doesn't use the interlacing hack to reduce bandwidth.

The crystal ball is very clear here:

a) video is increasingly processed with computers (whatever form they may take), not with analog circuits; so progressive would be better, and

b) non-progressive TV displays are disappearing completely.

Today we have to shoot interlaced in most cases, then deinterlace to do post work, then reinterlace to get back to say 1920x1080i, and finally deinterlace this one more time for the plasma/LCD/DLP/OLED/etc. display. Duuuuh!

Yea - I want it. You buyin? :-)

Interesting, thought that there might be a real solution for $16,000. Then I read the part about it being part of a Sub-system able to use 1,000 foot cables to connect this unit to the processing system. Maybe, just maybe it will cost more than $16,000 for a usable complete system.

Figure about 25K if you want full SDI HD/SDI output with an RCP. On paper, looks great. Unfortunately, won't be able to see one for at least 3 weeks or so.

I'm with you on this one. To answer your question the DVX100 writes 24fps into 60i with either 2:3 or 2:3:3:2 pulldown (23p or 24pA). This as Barry points out technically doesn't much with 24p and not at all with 24pA as they pull down can be removed and the fields merged to yield genuine discrete 24fps.
Still as you say it'd be nice to be able to avoid all that number crunching in post and I'd add that silly YUV fudge as well.
Good news is I hear Sony are working on this and some of the new digital film cameras do run such systems, the cost is a bit prohibitive at the moment but it can only come down. Sadly the optics to do justice to such systems will always be very expensive.
