Hey guys,

How can I get noise less shadows? Bringing down the Master Ped seems to work in some ways but it gets way too dark. Coring to the max but it doesn't seem to help. What tips can you give me? :)
 
I'm also curious to find this out as well. I tend to get a good amount of noise in shadows and it's pretty annoying.
 
Your not the only ones guys.
When the camera just came out there was a whole discussion about this. Some saw it didn't mind it other almost went gaga over this.
And others will say you have to buy a expensive hd monitor and have it calibrated ...... by a profesional .... yeah that will help.
The only thing that seemed to work is crushing the blacks. negative master ped.
I also wondered if this has more todo with the avchd codec and less with the settings. But then again the hpx 170 owners complained about this to.
For now I learned to live with it and try to expose my subjects properly as much as possible.
With that said Im having some good times with this camera. HMC 150 is just sweet.

add :
Even though I mostly shoot with Cine D , I remember getting less noise with Cine V.

I know you can get some really clean black shadows without having an overwhelming dark footage from some night shots I download from Vimeo(will try to find it later and post it here).

Any expert willing to share their settings?
 
The lowest noise setting is the B.Press ("black press") gamma -- clean at the expense of dynamic range.

Increasing Detail Coring (+2 or +4) helps and doesn't dramatically soften the image.

Lowering "detail" in-camera and doing sharpening in post also helps -- as higher in-camera detail settings also sharpen noise. Remember, the appearance of sharpness has nothing to do with resolution -- meaning that -7 "Detail" has the exact same resolution as +7 Detail.

Cine-D is a dance party of noise -- the price of dynamic range. Cine-V is less noisy -- again, at the expense of dynamic range.

Hmm, I have to see a comparison to understand that. What exactly is "Details" then? My understanding is +7 Detail will be sharper?

Ok, found a very good low light footage from Vimeo
http://vimeo.com/2039485

Matt's settings:
cine-v
cinelike
-20 master ped
+2 chroma
720/24p
1/48 shutter
no gain
preset 5.6k white balance
 
There is a free demo version of the NeatVideo plug-in on their site, and you can also search the DVXUser forums for posts from several different NeatVideo users.
 
check out some frame grabs from my recent lowlight shoot:
http://dvxuser.com/V6/showthread.php?t=180566

used cine-V with masterped -7 and NO gain.
cine gamma and color matrix.

would like to see someone's b.press samples to compare to.

shot in 720_24p to match the A-cam, but otherwise would've shot in 1080_24p for the xtra bit of color sampling for less noise.
 
I just used the demo of neatvideo, and I'm blown away! I'm buying it tomorrow! It does soften the image a little, but the sharpening works well. I don't know how they do it so well. I'm just waiting for a catch (other than long render times). Once processed properly it looks as smooth as the super expensive digi-cinema cams. I hope the company is doing well, because I think this is a wonderful plug-in without an equal yet. I always worry with niche things like this that are almost essential, that the company will disappear one day. Ahem... VisualHub anyone?

The NeatVideo plug-in ( www.neatvideo.com ) can clean up just about any video noise and retain full quality of the original video. Best $100 you'll ever spend.

just played with the demo in AE...the process seems a bit tedious.
its very exacting, needing to be fine-tuned for each clilp it seems.

it does suggest that you can create a general 'noise profile' that might work for a bunch of clips.

they don't have a plugin for Edius unfortunately, so i'd have to resort to using it in AE on a final export from Edius. in that case i'd need a general noise profile that would work for all the shots contained within the exported video clip. i'm not convinced that's the best or easiest way to do it though as one wedding video may contain indoor and outdoor shots with completely different noise profiles.

conversely, for cleaning up individual clips it does seem super powerful!
