the big question left in the P2 flow
-
That’s what happens on DVCproHD tape, but all indications are that the P2 system is a bit more intelligent only recording what it needs, and that has been indicated so for the 720p24.

Several people have mentioned HD D5 as a mastering format, and while HD D5 kicks major butt, I will mention the same comments I made regarding HD SR, which is that the deck is too expensive to be intergrated into the workflow of a $9000-ish camera. That deck and a P2 camera combined would actually cost more than a Varicam and the 1800 DVCPROHD deck. And it rents up here in NY for around $1800 a day, plus the required insurance. Now if I had a feature film or some sort of long format project, that’s not a problem, but that’s not a deck I could rent on a continual basis or purchase to integrate into the P2 workflow. It’s a matter of budetary mismatch. The Panasonic AJ-HD3700A HD-D5 deck (which records 1080/24p) at $100,000 is simply too expensive to be practical with an under 10k camera.
I’m positive that panasonic will annouce some sort of solution that doesn’t require the use of deck that costs over 10x what the camera costs. The ususal budgetary match is that the required deck costs less than the camera itself, but is somehat similar in price.

Graeme is 100% correct. The great benefit about shooting to P2 is to leave the limitations of tape behind- including the necessity of shooting discardable or repeating frames. It wouldn’t make sense to re-introduce it, since those frames are discarded “upon capture” and with P2 there is no capture.

I think (personal opinion, NOT Panasonic statement!) that there will be a version of 1080/24p from a 1080/60i with pulldown – like the 24p of the DVX100. How this will be acheived, I don’t know if/yet. This would be an extremely easy workaround which will allow people to use AJ-HD1200 for instance as a mastering format.

Yeah, that sounds like it could be pretty cool and do-able. I’m still waiting for our friend Jan to chime in with some official word. Don’t be shy, Jan! This isn’t the HDV forum- we like you here!

Until the official specs are out we do not know how 24p is done on this camera. The fact there are two versions, American and European makes me suspect there is frame-padding going on. Why else would they have make two versions?

I don’t think panasonic is going to give up on its frame tagging protocol. its embedded into the
decks, cameras, frame rate converters and FCP HD to boot. It is more of a number theory like implementation of a universal or special number to give it all incarnations of the dvcpro hd format. it has less to do with tape per say. -
[George] “I don’t think panasonic is going to give up on its frame tagging protocol. its embedded into the decks, cameras, frame rate converters and FCP HD to boot.”
Well, that may be the case as of right now.
But, there is no need for a deck, the camera is new, if they do away with the tagging protocol, then there is really no need for the frame rate converters, and FCP is coming out with a new version. So, I think anything is still possible.It is more of a number theory like implementation of a universal or special number to give it all incarnations of the dvcpro hd format. it has less to do with tape per say. “
I’m not sure I agree with that. It was my impression that the only reason the frame tagging was used was to workaround the limitations of using the tape transport.
Anyone else want to chime in on this?

I think Luis is right-
1. One of the primary benefits about moving away from tape is getting to move away from needless frame padding. This is why this technology is the future for all cameras- not just a clever thing Panasonic is doing with one speciality camera.
2. Panasonic is going to have to release new P2 codecs for the upcoming FCP 5 anyway to make the P2 stuff “edit ready”- plus introduce their new DVCPRO HD 1080/24p. So it’s almost certain that the new codecs with new protocols will not need frame tagging.

Frame tagging is to keep the tape running at a constant speed. On P2 there’s no need for it at all.
