I have figured a lot out but I am not there yet …. maybe someone can steer me over the finishing line…………
I gave up using the Mask Generator once I realized it was just a way to convert your clip into monochrome and that could be done using desaturation in HSL and then levels. I believe it is setting the blending mode of the top monochrome layer to “multiply (mask)” that makes it into a mask for the layer below and not that it was created in Mask Generator. Not sure though coz it still doesn’t work.
CURRENT SITUATION
==================
I have 3 identical layers on top of each other.
I made the top layer into a mask by desaturating it then using levels. It is monchrome now with the background black and the person white.
I set the layer blending mode of this top layer to “multiply mask”
I left the blending mode for the 2 layers below at the default setting.
I set the 2nd layer down as “compositing child”.
The bottom of the 3 layers is where I will apply luminance adjustents to reduce the exposure of the background. The person should remain unaffected by the changes on the bottom layer.
But it is not working. Instead of seeing the background on the bottom layer coming through I just see black, the black where the background has been blocked out from the second layer I assume.
Can anyone advise me how to get it working? Is it a problem maybe with the options in the preview window?
Thanks compassionate ones
