Nice tip to hide the banding. However, when you do Dithering, you usually do it when downsampling your signal, so here it would be when the camera encodes the video files, it should use Dithering to have smoother looking gradient. Adding noise in post will just distract the eye from the banding, I think. Also, the banding that you see in the first place with an 8bit codec on the GH4 is most likely due to the H.264 compression, for instance if you look at those three pictures I have included, one is in PNG 8bit/channel, no loss of information, the other one is JPEG 8bit/channel, lossy. You can clearly see the banding in the JPEG picture whereas I can barely see it in the PNG one, or maybe what I see is due to my shitty laptop TN display. PNG gradient: http://postimg.org/image/wb5o7976z/ JPEG 75%: http://postimg.org/image/mrxc0lj1b/ JPEG 100%: http://postimg.org/image/u5ouxfsvp/ note that I chose such a slight gradient on purpose, as the less difference there is in the gradient, the more likely you will have banding. The only way you can see the banding due to using "only" 8bit is by grading/color correcting it heavily, like I did here for the previous picture: http://postimg.org/image/oc2ogiz1j/ Again, that doesn't remove any value from your tip here, I am no videographer and I just wanted to add some technical precision so that you know what causes what.
