Trying out Power Director.
How do I apply incremental changes in the color magic box. There are various changes that can be made such as white balance, color balance, lighting etc. When I apply one of these changes and then try to superimpose another, it does not work.
eg: I apply color hue and saturation changes. Then when I try to use white balance or lighting changes, the last made changes disappear and only the latest change shows, ie, the hue and sat changes made revert to the original and only the white balance shows.

I cant make incremental /additive changes.
