Panasonic G7 Video Noise

To me, the "noise" on the subject's pant leg looks more like moiré.  Did the pant fabric have thin bands or closely placed pin stripes?

I don't know if there is something peculiar to Adobe Premier, or a particular export setting thereof, that might "bin" rows of pixels and thereby aggravate moiré.   Was the issue less noticeable in the original 4k footage?  Ordinarily, moiré is limited if the sensor pixel count more or less matches the video resolution.

As an experiment, you might try uploading a 4k version (at 100mbps) to YT, then view the footage at a 1080p resolution setting, to see if the results appear any different.

I don't notice any noise in the stationary black spaces.  Maybe that's my own lack of optical acuity, but perhaps many or most viewers won't notice anything either.

Another test would be to shoot some video at assorted ISO levels with the lens cover on.  Then you'd confirm the actual amounts of noise likely to appear in black portions of your frame.

You could reduce the distraction caused by pixel noise or moiré by using a radial blur filter to soften peripheral areas of the frame.

All I know about the G7 is that is it supposedly performs slightly better than the GH4 in low light.  Most reviews report noise problems only at ISO over 800 or 1,200.

Ok here is a 4k, 100MBps export of the footage. The footage looks as noisy on camera as it does out of Adobe Export.

YouTube DOES process and compress footage to about 45MBps bit rate for 4k. However it is only making the artifacts larger and blockier than normal. On the non-processed footage they appear much grainier.

The clothing is straight, plain black dickies pants, and the side of the truck bed is plain black. You can see the noise in other areas of the image as well, not just the blacks. Black is just easiest to spot it.

Maybe I'm being overly critical since I stare at my own footage ALL the time. However I haven't noticed this in other people's G7 footage.

Try ignoring the exposure meter and over exposing it just before you blow out whites. That way  it will capture more shadow information and I think it will solve your problem. Its easier to bring highlights down in post than to boost shadows with our sensor.

The problem there is I have to dial up ISO to achieve that and once I hit 800, noise is absolutely an issue.  So you are back to the same problem.  I get what you are saying and I will practice different exposure goals and see how it goes.  
I need a quicker lens I think, so I can open up a bit more and keep my ISOs down.

Alright thank you for the input.  I'm probably being overly critical of my own stuff.  Like I noted before YouTube compression it is more grainy noise than artifacts.  But to most folks the artifacts are absolutely more noticeable.

Yea, my next purchase is the 12-35 2.8f lens.  I almost bought it this weekend, should have when I saw a deal.  Thanks.

Thanks Jody, that is good info.

Hi man ! I have the same issue but right now, not even minute ago i thik i solved this issue. So i just turned on camera without removing cap on lens, because i just wanted to check something, i looked through viewfinder and i just saw a black picture because i didnt remove lens cap and i saw a lot of noise on that black picture, then i went ti change "photo mode" and at that moment i used cinema mode with custom settings and when i started changing modes noise was changing so much, even on standard you have a lot of noise, for me best photo mode is vivd, you cant even see noise... Just try it, turn on camera without removing lens cap and then by looking through viewfinder try to change photo modes, i hope it works Good luck !
