Just heard Jan speak on DV guys abot the HVX-200
The new info i got out of it is that it will indeed record any frame rate between 4 and 60, and that it uses the same pull down as the DVX for 24p when recording to P2 (not sure why they dont record just the frames needed)

Damn, I missed it.
I was under the impression that the frame rates for 720 weren’t set in stone yet, though I know Jan was pushing for the same variable frame rates as the varicam (everything from 4 to 60).
As far as the pulldown on the 24P, everything up until now said that it will indeed perform a pulldown when shooting 24P in 1080P mode, but that in 720P it would only record the frames needed.
Are you certain she wasn’t specifically discussing the 1080P mode?

hey luis,
today’s show should be available for download w/in 1 hour….i’d like to hear what jan said as well!
-
ok, just listened to the show…jan said, “select” framerates between 4-60 frames…does not necessarily mean every frame in between.

I tried to extort an answer from her today at NAB about that as well. All she will commit to is that there’s 4, there’s 60, there’s 24, there’s 30, but she won’t specify what frame rates there are between 4 and 60. Other than to say that yes, there are frame rates besides 4, 24, 30, and 60. I asked “are there ‘many’ frame rates besides those?” No answer.
So, more info will be forthcoming, I expect that there will be lots of frame rates, but probably not every frame rate from the VariCam.

I hope there’s also 25 and 50…

I really like to know (a good technical reason) why this camera is going to add the pulldown to the 1080p24 mode instead of using all the 100 mb/s bandwidth on the 24 frames per second.
-
Me too.
Maybe the reason is in dvcproHD dsp chips and Panny designs new ones after every 5 years, so this model is still done with the old ones… -

There is no provision in the DVCProHD spec for 1080P.
As an analogy, there is no provision in the DV spec for 24P.So, in the same way that Panasonic added a pulldown to the DVX and carries the 24p footage in a 60i stream, they will add a pulldown to the 1080P24 footage on the HVX and carry it in a 1080i stream to be able to record it as DVCProHD on the HVX.
It is a limitation of the codec.
To be able to record 24 frame 1080P without the pulldown would have meant a new codec. Part of the advantage of the HVX200 is it’s use of an established coded with an established workflow and editing support.The disadvantage of this, as you pointed out, is that 20% of storage space is used up to store pulldown frames that will eventually be removed.
I think that’s a small price to pay for 1080P24 footage.

I think that by introducing a new media (p2), it would have been logical time to extend the old codec at the same time. Pull-down frames could added at the export from p2 to legacy tape deck.
But this would need new codec chips to camera… -
I, too, was also hoping that Panasonic would take the opportunity of the new camera to intoduce a new codec that made use of the entire 100 mb/sec for 24p. It made sense for tape to have to have one codec that recorded 60p and below, but with P2 it seems that there’s an increased flexibility. And the codecs that the HVX-200 are shooting to are upgraded versions of their existing codecs. That’s why they wouldn’t be “edit ready” without FCP5.
But I’m content with the upgrades that P2 and the new camera will bring us. You can’t have everything at once, I guess- certainly not for $6000. And we should keep in mind how low the cost of this camera is while we list its shortcomings. I’m sure new codecs will be on the table the next time around.
To be honest, I’m more upset that Sony won’t realease its HD codec to Avid or FCP for native editing. At least Panasonic did that.
