Author Topic: Blue Screen -Adobe premiere matho

Hi,

I want to do some blue screening in Adobe premiere. I have got the actual key to work quite well...ie sharp, minimal blue outlines etc.

However i want to know how to apply a filter to only the subject in front of the screen. IE i want to change colors etc. Everytime i try, it affects the blue as well.

Is there anyway to key out the blue so it is not affected by filters.

thanks

What kind of filter is it?

easiest way that I can think of is blue screen it, render it, and then add your filter. Other wise you are going to have to do some sort of mask.

render is keyed out so it has an alpha channel

im not sure if you can do this in premiere but try to make a seprate file as the alpha channel.

apply filter then use the second file as the alpha key.

Thanks Guys.

I will try to create a seperate mask file.

The filter that i want to do seems simple. I want to be able to change the color of the actor or object in front of the screen, without affecting the blue of the screen.

Thanks again.
