Re: 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.
