How to avoid black bleeding into adjustment layer?

[bikelike]

In the attached picture you can see what I mean. I like to soften footage by applying a light blur on an ajustment layer, set the blending option to 'darken' and reduc the opacity. Subtle effect. However the borders of the image take in a lot of black. A white color matte, nor a solid white jpeg image would make a difference. Is there an option to set the very background to transparent? Or any other sollution apart from trimming?

Thanks!

Use Gaussian Blur and check Repeat Edge Pixels.
