I’ve never seen/noticed this noise you mention in the field, nor have I heard any complaints from clients or post houses. I’ll be running some tests though! Thanks for the heads up.

The physical glass filter “D” that you roll in manually is 6300k in preset, assuming that your preset is set to 3200k in the OPERATION/WHITE BALANCE MODE MENU. Likewise,the physical glass filter “C” is 4300k in preset. If you want to bypass the glass color correction you can leave the physical glass filter on clear–3200k and change the OPERATION/WHITE BALANCE MODE value to whatever you want in either preset, awb/ A or awb/B. I often set my preset to 5600k and use the clear filter, “B”, under HMIs or Kinos because they look too warm using the daylight 6300k glass filter “D”. The C and D filters are also more dense than the clear filters A and B so sometimes it’s nice to be able to change color temp without losing light by changing the menu instead of the glass. Careful though, because if you set your preset to say, 4300k, and roll in the glass filter “C” (4300k), you’ll actually be shooting at 8600k. Roll in glass filter “D” and you’ be shooting at about 10,000k.

Thanks John. That helps. To be clear though….

…HDX-900 in System Mode 1080-59.94i and Camera Mode 30P, I’m recording progressively in 1080, and there’s no pulldown per se because it’s 30 progressive frames over what is essentially a 30 frame/60 field system?

But that’s not the same as 1080P. Can 1080P only be achieved by using a camera with a native 1080 imaging device?

And finally, again just to be clear, you think that any loss of vertical resolution in 1080i vs 720p is negligible relative to the increase in horizontal resolution?

Again, thanks!

I too, have been under the impression that 720-59.94P would be prefered to shooting 1080-59.94i when using the HDX-900. Recently I’ve been asked to shoot at 1080. My concern is that the clients are expecting 1080P and that the HDX-900 is outputting 1080i.

My question is, when the Camera System is set to 1080-59.94i and the Camera Mode is set to 24P or 30P, am I essentially capturing at 1080P? Or is it still recording and outputting an interlaced signal that may have frames that are made up of non-identical fields(pull-down), and with less vertical resolution(at least where there’s motion in the frame) than material recorded at 720-59.94P?

Any guidance is appreciated.

As I understand it, your blackest black is 0 in any digital format, whether HD or SD. The ability of some cameras(like the SDX-900) to spit out a signal with a 7.5 IRE set -up allows you to feed older CRT analog monitors without the picture looking too contrasty.

I’ve fed a down-converted HD signal into a SD waveform/vectorscope for setting up both Sony and Panasonic high definition cameras with good results. I usually set the master blacks 2-3 units above zero though, especially when running and gunning. It’s easier to pull those blacks down in post if you have to than to do the opposite if they’re crushed.

[Redflag] “You can use 2/3 inch lenses with an adaptor,”

How much image do you lose through the adaptor with a 2/3″ lens? Is 5.2mm still 5.2 on the 1/2″ chip? Is it more like the equivilent of 8 or 10mm in a 2/3″ system?

I bought a Nikon digital still camera, and found tha a 24mm lens for my film body yielded the equvilent of 35mm on the digital body?

Anyone know if this might be a similar situation with 2/3 vs. 1/2 inch chips?

Seems to me that blacks and gammas have a lot to do with color saturation, and that the VariCam factory settings for these two items are set pretty high. Lower gammas and blacks seem to equal more saturation. I havn’t done any film-out work–most of my clients expect to see in post, what they see in the field. I’ve had pretty good luck, sat-wise, with blacks 0-5 IRE and gammas 60-70 IRE. Though I am pushing some of the matrix and CC numbers toward their upper limits. Like others, I wonder how you really know without a waveform and a chart.
