I have created an animation that includes my logo. But this does not fill the entire screen. Therefore everything around the logo shall be transparent during the animation runs (so that you can see the gameplay in the background), but still be somewhat blurred. How do I do that?
I'm not entirely clear on the exact effect you are trying to accomplish, but this should get you close.
1. Create a new adjustment layer above your gameplay footage.
2. Apply the blur effect of your choice to that layer. Everything should be blurry now.
3. Place your logo animation above the adjustment layer.
4. Set the track matte on the adjustment layer to alpha or alpha inverted.
Alpha will blur the area inside your logo. Alpha inverted will blur the area outside your logo.
would you Please put a screenshot so we can Give a Quick Solution ?
