so the best way is a background can blur what behind it .
Well... you could try and create custom shaders for GS, and theoretically create a blur that samples the background, but not sampling in real time.Blur Shaders essentially just take a pixel radius sample and blur to the colors sampled by a majority coloration per radius. While GS can't sample in real time. It is possible to pre-sample a scenes colors or sections of a scene and then create nodes that broadcast or give coordinates to which colors are currently in that section.With that in mind using a small pre-blurred white/black image with opacity not at maximum and having that being fed pre-sampled color information in real time based on coordinates, you can create a dynamic blur effect. But it will be quite rudimentary.
@Socks Haha for sure, photoshops blur are so nice.

. . . Surely taking the background image you're using, or a screenshot of a "typical" scene, and applying the blur effects in Photoshop would have a sufficient effect?
Pah can't see how to attach a file to an edited post. I updated it a tiny bit and went to re-attach it and seems I need to post again to do so. Sorry it's rather large, I just grabbed a random image off Google.Aaand I'm going to need to update it again, to rest attribute when you switch scenes. Just hit reset if it doesn't work first time.As you can see, as long as the actors aren't big and white, the effect works pretty well even with actors under it - as long as the image you're using to blur is generated from a broadly similar picture to what it's being put over.
