I have taken day and night shots for my corporate video on the dvx100. its my first time using a panasonic camera and god, there is so much noise. I am really unsure about the settings and all.

Can someone tell me a setting (scene file etc) which is NOISELESS? If theres such a setting, or whatever to look out for? Theres so much noise its so annoying.

Or rather can someone tell me wads causing the noise? Im quite new to this actually, but the weird thing is whatever lighting conditions im in its still noisy, and my gain is adjusted to the lowest

Thanks to all in advance
 
If you have your detail level turned up alot, either turn it down a little bit or turn up your detail coring, which smooths out the noise created by detail level
 
Sounds like it may be gain related

Are you applying any gain at all?
What about your "auto" setting on the side of the camera - are you using this option?
 
Klizz,

Which model, the original DVX100? Not A or B?

Just because you are on L gain, doesn't mean gain is off. You can make sure in the menus that L = 0db. Check that.

A lot of the noise is little noise that gets exaggerated by the sharpening. Turn Detail down and Coring up, to taste. You might start with Detail -2, Coring +2, and go from there. Much smoother and more natural.

its the dvx100B and could it be that the camera is physically spoilt and thus causing the noise? ill try reducing the detail and increasing the coring. Any other settings which will cause noise? Rather new to this. sorry.

My gain i am pretty sure is zero. ill recheck again.
 
That's extremely clean compared with what you normally get from the 100 or the 100a. Add more light. If you can't deal with any noise, get a pd170 instead, and I mean it. If you're just shooting 60i, it's a cheaper camera and better for those purposes.

That said, using an 85b filter instead of setting your white balance to 5600k, turning your detail coring to max, avoiding cinegamma and cinelike color, and turning down your master ped will decrease noise. But, in this case, you need more light.
 
i worked with alot of pd170s before the dvx100b. must be what set my standards of noisy video. haha.

would the dvx100 deal with noise better in interlaced or progressive mode? thanks for the reply
 
how does white balance affect noise? and wad exaclty does detail coring do? I worked alot with pd170s previously. and totally new to the dvx 100. haha. thanks for the reply.
 
The dvx can be a very noisy camera, or a very clean camera. It all depends on how you light it. Watch my movie Stricken to see how clean the DVX can be with some post tweaking. http://www.youtube.com/watch?v=aap-11vrYaM

I lit very brightly on ALL scenes and created the look I wanted in post. I used Premiere Pro 2 and After effects pro 6.5 and 7. I was able to remove ALL noise with this method. see how it looks in my movie shot on the DVX100b and read this tutorial. I hope this helps.
Tips to eliminate noise.
1. Tons of light
2. Correct white balance and black balance
3. Master PED between -4 and -7
4. Detail at -3
5. most setting at 0
6. correct exposure
7. Gamma curve "Black Press"


Noise Removal Tutorial:

Step one, Export from Premiere Pro 2.0 in Uncompressed Filmstrip format for After Effects. Step two. Import into After Effects. Drop into a 23.976 composition. Set the composition several frames beyond what your clip length is. Apply Remove Grain. Change the viewing mode to final output, instead of preview. Fiddle with the Noise reduction slider under the noise reduction settings. Try to get a mix between the most detail and the smooth picture. If there is a ton of noise in the background that just seems to not go away, bring the slider down to about .2 and then enable temporal filtering. Set it to 100% and bring motion sensitivity to .9. Observe the results and then play with the noise reduction slider again until you achieve the look you want. It will make much more minor of a difference when temporal filtering is one, but it does help.

Output as an Uncompressed Quicktime or AVI format. NOT as a filmstrip again. For some reason if you export as an uncompressed filmstrip, it stretches the clip and makes it stuttery.

I hope this little tutorial helped!

Yep 24p No prob! I hope it helps!
 
Even in the best of situations, the DVX has a bit of noise, but it's often compared favorably with film grain. It's certainly not the multi-colored noise of older video cameras. It's rather pleasing and organic. There isn't really a need to completely eliminate nosie altogether. There always grain in motion picture films, and no one complains about that.
