Hey guys,

Quick questions to ask,

1. Can the HVX be shot on 1080 progressive 24frames per second?

2.I have heard that 1080i and 720p theres no difference to it, i guess shooting 720p would be better cuz u get different fps to choose from..

Thanks for helping..

You have to separate how the camera captures information from how it records that information. The HVX200 does not have 1920 x 1080 CCD's, it has much smaller CCD's in terms of pixels (even less than 1280 x 720), so it's basically "uprezzing" the captured image to be recorded at 720P or 1080i, depending on what you tell the camera to do.

So it can do different frame rates in progressive-scan capture, especially 24P, the only issue is whether you want them recorded as 720P or 1080i, with a pulldown to convert to 60i (although I don't know if all the shooting frames rates are available when you switch between 720P and 1080i recording modes.) If you shoot 24P, it would basically get a 3:2 pulldown in the recording to be stored as 60i/1080.

(I don't think 24P/1080 is a recording option with the camera but I could be wrong.)

So it sort of depends on how you plan on doing the HD post for the project. Personally, I would assume that it would be a "cleaner" post process to stick to the 720P recording mode if shooting progressive-scan rather than deal with footage upconverted to 1080i interlaced-scan with a pulldown, but if you are shooting for a final 1080i master, it might not make a difference.

Variable frame rates are only available in 720P. In 720 you can select 24P"N" which produces 24 discrete frames per second, or 720/60P which adds pulldown depending on the frame rate you shoot (just like the Varicam).

1080 recording is always 60i.

The camera is a 720p camera with the 1080 swtich thrown in as a marketing gimmick. It really doesn't do 1080 to any degree and that is why you cant really see the difference. Stick to 720, its a perfect fit. Bigger is a little better on a camera that cost >$40k but on a prosumer camera like this, you really have no advantage to shooting 1080. It does wonderful 720p so I would go with that.
