I personally believe that working with dissolves is easier with the Nucoda Film Master. With the Resolve, it has some limitations that make it a little trickier. If you put your dissolve in the track within the Color tab, you must use the exact same nodes in the dissolving clips. The dissolve here basically just interpolates your nodes, moving your values from your first setting to the next. So, if for example, you have a node with a qualifier that changes values from the first clip to the second clip, then you might see a sort of “morphing” within the dissolve (which I should probably start calling, “dynamic”, in this context, rather than “dissolve”). Since it is a dynamic, the clip is still whole and applying a saved grade would erase that dynamic. As opposed to how the Film Master does it, splitting the clips in two and placing an actual dissolve over the cut. Since the two parts are separated, it’s easy to just apply a saved grade to either without affecting the other clip or the dissolve.
I’ve noticed a lot of engine searches for “dissolve in Da Vinci Resolve” or something similar. I tried doing the search myself and I didn’t find much. But, if I’m not mistaken, the Resolve manual has instructions on this. But anyway, as a quick reference, here’s how to do it. Depending on your situation, you can create a dissolve effect either in CONFORM or COLOR.
