Hasta La Motion!

I am going to be receiving some stereoscopic material that has already gotten picturelock and i wanted to do colormatching and interocular distancing using ocula (this could apply to any full frame effect on any type of content). How will nuke handle something like colormatching or IO distancing when the scene changes? Will the effects be applied globally based upon the initial shot, or is nuke intelligent enough to automatically detect scene changes and apply its effect dynamically?

If not, am i doomed to using merge/time offset combo’s along with my effect nodes in order for the effects to be accurate over time?
