Best Noise Reduction Settings for HPX300

Just received my HPX 300. Know noise has been discussed before.
Any coring, ped, detail and saturation settings to share?
I have been shooting Cine V with my HVX 200, and plan to continue using it for the 300.
Thinking by turning down the saturation, I might reduce noise in blue skies and shadows. Love the saturated panny look, but maybe it would be better to goose saturation in post, and keep the 300 a bit flat on ingest.
But then again if I boost saturation in post, noise might come back?
 
What firmware version are you running? If it's not a brand-new HPX300, make sure you've got the latest firmware installed, which featured a major reduction in noise.
 
Yes, if you have the newest firmware (9.30), noise is not that big problem anymore.
But Gain -3dB is still not bad i think.
And who sets the ped to +30? Nobody i believe... I use unbelievable +3... No issues :-)
 
I have fairly limited experience with the 300, and no experience with it since the firmware update, so any suggestions I make are general and not specific, but the first thing I'd do (as Emmet said) is drop that master pedestal. I don't know why it comes factory-set so preposterously high, drop it to zero or even negative. Turn on the waveform monitor and put the lens cap on and try to get a nice clean flat line of absolute zero.

As for coring & detail, one way to go about it is to shoot a gray chart, and turn on the waveform monitor. Look at the transitions from one step to the next, see if the waveform shows it as a clean transition or if there's a big nasty spike at the transition point. You want the detail as high as you can get it without causing a big ugly spike. The smaller the spike, the less "edge enhanced" your footage will look. Once you've got the detail set right, look at the crawling noise on the waveform, and turn up the coring to try to tame that.

As for saturation, I pretty much always glue the saturation on +2 on any Panasonic camera I use. It makes for a rich oversaturated look that I like. It doesn't contribute much in the way of noise on the CCD cams, but I didn't experiment too much with the CMOS camera so I don't know; you'd have to really A/B it on a monitor (or record some footage and split-screen it and play it back) to see how much of a noise difference it makes.
