Hi there, 

Working on latest Avid MC.  Working with an imported title in two parts along with a BG.  I want to sweep the firat part of the title on from the left and use a BCC Channel Blur dissolve, and then bring the 2nd part of the title on with the same effect.  The issue is the BCC blur affects the layer below.  So the BG gets blurred with the first title, and when the 2nd title comes on it blurs everything belos - including the first part of the title.  Is there a way of having BCC only affect the layer it is applied to?  Thanks in advance!

I think you need to check the Apply to Title Matte box in the settings for your chosen effect. Also if you are applying the effect to a matte then don't Alt+drag the clip on to it, just drag it straight on top. This is counter-intuitive to how you usually stack effects but once you check the Title Matte box it should respect just the matte below it and not affect the background.

this is not working here.   no combination of applying on to a matte key clip with a diffusion effect dragged or alt dragged on to the clip gives the result required.  applying to title matte does not do the trick.

the only way this works here is to double click the matte key clip, then drag the diffusion to the v1.2 track and then drag the same effect on to the v1.3  track. that way the fill and the matte have the same amount of diffusion.

what am i missing?

any thoughts?

The method you describe (stepping into the effect) is how I was going to suggest fixing the problem.

Here is how Boris says to do it - you may need to set some layers to have a background layer of "none" depending on your stack and you may need to alt+drag some effects but not others.

FWIW - I took a title (matte key), dropped the Boris BCC+ Diffusion effect on it (without holding alt), opened up the Composite drop down, clicked Apply to Title-Matte, opened the FX Editor and chose a texture, clicked ok and brought the blur level (under the diffusion parameters) down to zero. I can now see my chosen texture overlayed on my title without affecting anything in the background. 

From here I'm free to play around with my blend mode, colours, blur amount etc. Works as expected.

....this is working here now...not sure what was missing the first time around....perhaps the combination of Background: First Below, Apply to Title-Matte and Invert Title-Matte never got done here before now, which is what it took to get the effect to respond....
