So forgive my technical ignorance, DrDre, but how exactly does this work? Do you have to manually attach a shot to a source frame? Or does it take the bulk of reference frames you have and build a universally applicable model to grade any shot with?
And how is the grading accomplished? Does it just take the color palette of your references and match the source to it as closely as possible?

A detailed explanation of what steps the software takes would go a long way for helping a non-technically minded person like myself to comprehend what’s going on here.

No, you don’t have to manually attach a shot to a source frame. The algorithm just needs a set of source frames and their references. These references are not the original reference frames, but the source frames matched to references by the color matching algorithm, such that the colors of a pixel in the source can be directly mapped to the same pixel in the reference. For any new shot that you want to regrade, the algorithm automatically assigns higher weights to the references, that are more most similar to the new shot. There are no manual steps involved. You just point it to the shots you want to regrade, and presto…
