While we ColorCorrect or Grade a CG render (with Alpha), which of the following method works best
Method 1:
-Create and connect 'Premult' node to the CG footage
-Create and connect 'Grade' node to the 'Premult' node
-Create and connect 'Unpremult' node to the 'Grade' node.
-Now when we adjust values on the 'Grade' node, it will also read the Alpha channel and we get to see nice edges while color correcting.
Method 2:
-Create and connect 'Grade' node to the CG footage
-Also connect 'Mask' input from the 'Grade' node to CG footage (which will automatically read the Alpha channel from the CG footage while adjusting values on the 'Grade' node)
For me, both methods works good, just that 'Method 2' is simple with minimal nodes.
Does anybody has any work experience on both of the above and feel one is better than then other?
