Using information from the Video Scopes tab, you can adjust the Whites and the Mids
sliders to make the two spikes of the Histogram match more closely, so you get
comparable luminance levels. Moving one invariably results in some movement in the
other, but keep making your adjustments until their position approximates the
Histogram from the master shot.
8 With this accomplished, focus on the Parade scope. It shows that the second clip has
far more blue and green than the first.
Adding progressively more cyan to the mids brings the hues of the two shots closer to
one another. As you adjust the Mids Balance control, continue comparing the previous
shot and the current shot as outlined in step 7. Continue to make adjustments until the
shots match as closely as you need them to.
Note: Remember that your goal, in this case, is to balance all the shots in the scene so
that as the sequence plays, no one shot stands out from any of the others.
