Blockiness in green on export
I have a very strange problem… Using Premiere Pro 5.5.1, Mac OS X 10.6.8, NVidia Quadro 4000 and clips that needed pretty severe color correction to match another camera. The camera is a JVC HM100 using the XDCAM EX codec with 1080 30P framesize/rate. I have run a couple 3-way color correctors, a RGB color corrector, a gaussian blur and a luma corrector filter on the clips. I have them looking pretty good while in Premiere Pro, when I export them, no matter the format, H.264 or Prores, the green is blocky, like somehow there are only a couple of shades of green.
I’ve tried a bunch of things, putting the sequence into best quality mode, using high quality render, turning off MPE, nothing seems to help. I’m considering just doing the clips in Colorista II but wanted to ask if anybody has a simple solution to this?

Hi Keith,
It could be that you are now exceeding the color depth of the format, basically causing color clipping. For H.264, that would mean increasing the level / profile in your export settings.

turns out it was the RGB Color corrector filter, I think it may be a bug with the type of media I was using it on, which was XDCAM EX in a quicktime wrapper. Premiere Pro has some bugs when it comes to things other than prores wrapped in quicktime. When I took out the RGB color corrector the problem went away, but I had to use another filter to replicate what the former filter did.
