I have been having an issue when color grading lately with the C300.
After the grade, most blacks that are below 40 IRE seem to be artifacting like crazy on youtube. Whereas I don't see this from other people's work.
Ive tried these encode settings in adobe media encoder,
Quicktime MOV, h264
55'000 kbps
1920 x 818
Quicktime MOV, h264
35'000 kbps
1920 x 818
Quicktime MOV, h264
25'000 kbps
1920 x 818
Quicktime MOV, Prores 444
1920 x 818
But all of them just aren't cutting it and I dont know what I'm missing. My blacks are generally not brought down to 0 because the director wants a low contrasty look and some scenes were shot very dimly with only one LED to light the scene. On the other hand, we've lit darker scenes with several 1k's and Litepanel LEDs and while the highlights and midtones held up the blacks still artifacted hard.
Here is an unlisted link to a test video I made. Please don't share outside of the community.

Any and all info would be much appreciated!
