Resolve FX and Transitions on Clips w/ Alpha

Hi there,

I got a big problem. I have two video layers:
Track 2: Foreground building with Alpha Channel (it's cut out so to say)
Track 1: The Background

What I tried to achieve: I want to make a tilt shift effect, first blurring Track 2, then a transition to blurring Track 1 and having Track 2 fully focused. I used Resolve FX Lens Blur.

When I apply any Resolve FX, in my case Lens Blur, on Track 2, the outcome is not as expected. The blur is limited to the "cut-out" (where Alpha = 1) of Track 2.
Expected result: The blur should "bleed" into the Track below to give a realistic composite.

I tried the same thing with Groups on the Color Page. This is better, because now the Blur is on both Tracks, but I actually don't want it to blur the complete Track below (just the edges of the cut-out instead).

Now on the other hand, I wanted to use the Transition "Smooth Cut" on Titles - this time it works other way round. I'd expect the effect to only work on the Title, but it doesn't. Instead it deforms the Tracks below, too. I don't want that.

This is a bit counter-intuitive and pretty frustrating. All help would be appreciated!

Thanks,
Manuel.

Hey,
I'd do it with the background and foreground on the same track, maybe blended in the same clip, with a power windows around the FG and an outside node attached after...

The title issue is known, you will find some threads here around but I don't remember the main workaround. Try turning the title into a compound node before, or into a clip by dragging it from the viewer to a bin.
