Thanks for using Pro Color on the video JazzBox.
I see you had contrast -5
It would have looked better with the optimal settings in the guide, which have contrast at 0.
When you set contrast to -5 it doesn't give you more dynamic range.
It reduces the amount of tones between one colour and another = Less colour information in the end result even when you add contrast in post.
This is EOSHD Pro Color for Panasonic with Contrast at 0 (optimal, as in guide):
And this is at contrast -5 (see how the tones on the face are mashed together?):
