HVR-Z1 and 24P at DVinfo.net

Paul Brady · December 5th, 2004, 12:19 PM

Does the HVR-Z1 have true 24P like their $80,000.00 cameras in HDV mode. Can the HVR-Z1 shoot 24P like the XL2 24P in non HDV. Does canon and sony both use the same method of getting 24P.

Sony uses something they call CineFrame 24 which works by dropping every fifth interlaced frame over the period of 30 frames, thereby creating 24 interlaced samples per second. Although 24 samples per second are obtained, the sampling interval is not constant with a real 24fps camera.

Would the best situation be true 24P, which canon and panasonic has. So if I was shooting regular DV the XL2 would have better picture than the new sony. If I was shooting HVD it would not be as good as the proffesional camaras. Paul

Hi Walter!! Good to see you here!

Is that what it's really doing?? Ouch. I knew it looked bad but.... I know some cheapo Sony home cameras did that. Wow. How did you find out the details as Sony seem to be keeping tight lipped... No wonder why!

hi Graeme,

Steve Mullen said that is how they do it. It sure looks l like crap from my tests with it. As long as you are shooting dead people it looks okay.

Graeme Nattress · December 5th, 2004, 08:30 PM

Thanks Walter. Looks like I'll still be working on Film Effects then, adding features for HDV users.

I've heard CineFrame24 sucks but CineFrame25 is supposed to look great. Going from 25 to 24fps is supposed to be very easy. I'm not even sure if it's necessary unless you're doing a filmout. I'm probably the single most excited person on these boards to see what people can do with CineFrame25.

It should, but in reality it doesn't -- it even looks awful on still shots! We shot some resolution charts with the camera, and in CF24 mode there's an odd weird pulsing going on -- plus field-based flicker. It looks lousy on still shots as well as on moving shots. CF24 is completely unusable.

What medium were you using to view the footage. Was it live, was it a dump to computer?

This is a conversation we have a lot. Do a search to find other discussions.

We're talking about the Z1 or the FX1? The Z1 is supposed to be better.

Walter Graff · December 7th, 2004, 08:44 AM

Better? It has some extra features and XLRs but is the same camera with a different label.

Chris Hurd · December 7th, 2004, 08:59 AM

For a detailed list of differences between the FX1 and Z1U, see my extensive Sony HDV Comparison Chart here.

We don't know that -- there was some speculation that maybe the Z1 handled CF24 differently than the FX1 did. Chris Hurd assures us that there is no difference in that regard, so no, the Z1 would be no better.

But, until there's a final finished product on store shelves, anything could happen. I sincerely hope (for the Z1's sake, and for the sake of all the people who spend $5000 to $6000 on it) that the CF24 mode is somehow improved on the Z1.
