Great video. One question, when I rotate a trackball vertically (ie towards 12 o'clock), the white dot on the color wheel in Davinci moves up towards 11 o'clock, ie not straight up, but towards the left. Similarly when I rotate the trackball straight down at 6 o'clock, the white dot on the color wheel in Davinci moves down towards 5 o'clock. It seems off by 30 degrees. The same if I rotate the trackball left or right (towards 9 o'clock or 3 o'clock), the white dot moves between 8 o'clock and 2 o'clock respectively). This is with all trackballs. Is this correct? It doesn't seem right. I assumed that the trackballs would directly correspond with the Color Wheels in Davinci on screen.
The main reason to buy the mini panel is the precision it gives to the adjustments and from that you become faster at grading. So no, the deviation you mention is not the assumed or normal behaviour from the panel. I don't recall having any deviation when using my own panel, so I can’t say off the top of my head what might be at fault in your case. I recommend you to post your question in the blackmagic forum.
I'm not selling or buying anything. I only try to teach and train people some editing, gradind, compositing, mixing, media management, just about everything that fits within the field of post production of video.
