It doesn't look like Color Grading was ready for this new release!!!
1: Add color grading to any project, save the project. Reopen - VP17 opens the project but marks the file as being modified (* after file name in VP17 title bar). If you check the undo history it has all the items from the color grade available for undo. For example I modified the lift and gain. The undo history after reopening the saved veg file is "Undo Gain" and then "Undo Lift". These changes had been committed to the saved VEG file and should not mark the file modified after reopen!
2: Auto Adjust White Balance is not even close! Selecting Auto Adjust White balance in Color Grading adds a lot of contrast and I don't know what else but it's wrong. If the current frame/cropping has a lot of white in it the results are even worse creating too much black/dark colors.
3: Randomly the Color Grading controls are not responsive (frozen). Clicking any of the tabs (Input LUT, Color Wheels, Color Channels, Input/Output, or any controls in the window itself does nothing. VP17 is not hung, you can still use the menus, play the timeline, make mods, etc. but everything in the Color Grading Window is frozen. This sometimes happens on open of a project and sometimes during an edit session. Sometimes if I change the crop of an event it will come to life, sometimes not and I have to save and reopen the project and hope.
4: Sometimes separately and randomly, the White Balance Auto Adjust button is disabled (greyed) and pushing it does nothing. Actually might be an improvement over when it actually does do something!
