I am trying to boost the highlights of a specific area of my clip, so I added a Roto node, then connected the OUTPUT to the INPUT of a Shadows/Highlights node. I would like to comp this back on top of the original clip.
Could you please let me know which Comp node I should be using to obtain the proper highlight boost on that roto area without effecting the rest of the clip and also, which OUT should I be using on the ROTO node? I’m using the Output of the Roto, but I also see that there is Color Composite and Composite, so I’m no sure if Output is the correct one I should use for my case.
In zMatte, set Extract On to Luminance and use the Position and Range parameters to set your highlight Matte.
Use the Color Correction tab in zMatte.
The Develop adjustments will only occur in the areas of the matte created by zMatte, and you can comp it over a background.
Option 2 - zMatte with Color Correct or Develop
Connect a zMatte node to the Obey Matte input of a Develop node.
In zMatte, set Extract On to Luminance and use the Position and Range parameters to set your Matte.
Click the Color Correct or Develop > Obey Matte tab and enable Obey.
Click the Color Correct or Develop > Parameters tab and adjust the Brightness or Recovery down. The Develop adjustments will only occur in the areas of the matte created by zMatte.
Use the Roto node node cut out the areas with a shape to comp over a different background
