Unchecking the CLUT box has no effect on the Before/After images. But that may be just one side effect of whatever is happening, i.e., if I Uncheck CLUT and select Reset on the Manual settings (and never selecting a Preset), I expect the Before image to be the same as the After image. But that's not the case: the AFter image looses most of the detail in the dark areas.
In your video (thanks by the way) once you uncheck the CLUT the two images appear to revert to identical which is what I expect to happen.
So to recap my workflow:
1. open MOV in ColorDirector 2
2. select comparison view
3. notice that Before and After images are different (specifically the After image darker areas have lost detail)
4. uncheck the CLUT
5. The After image does not change
6. Reset the Manual adjustments.
7. The After image does not change
I also tried clearing ALL of the checkboxes under Global Adjustment Tools to see what effect it had on the After images: The After image does not change.
BTW, it's not completely nonresponsive, manual adjustments modify the After image as expected.
If this isn't enough of a clue, tell me what I can do to provide more detail.
I'm very excited to be able to color grade. Just need to get past this unwelcome modification of the images.
Thanks!
