Question / Help Creating a blur extending from the edge of a video.

I'm looking for a way to extend the edges of a video source through a blur effect. Since I'm having a bit of trouble describing exactly what I'd like to do, I'll give two examples. First, some tv broadcasters use this affect to show SD content in hd, with the edges of the SD content blurring into a static HD border. Second, if you look at http://www.youtube.com/watch?v=becjT1x0Egs you can see how they have the edge of the video game source extend and blend with the rest of the scene.

What is the easiest way to achieve this kind of affect? If I'm going to need an external tool to do it, do you have any recommendations?

Thanks!

It looks like what they are doing in that video is with a green screen + chroma key, a back-shadow effect, and arranging the video sources in skewed angles. The skewed angles and drop shadow can't be done in OBS alone at this time. However, chroma key is possible for people in the foreground.

As for arranging things on the screen, you can do that however you want. Just make an HD image, but that into your scene, and move around/resize the SD source underneath the image.

dodgepong pretty much explained it.

What these guys do is have a huge greenscreen behind their couch (camera bottom left) which they chroma key out. Top left of the screen is a partially transparent png image, which is arranged to go behind camera output and cover the game source a bit (this seems to create a feel that the game's image is skewed too, but it actually isn't). Bottom right is a skewed image with twitch chat in it and as dodgepong pointed out, you cannot skew sources with in OBS right now, but it's a possibility you could do it with some other tools (not sure I can remember anything right now though) and capture their output to OBS.

Honestly, I'm not sure. I don't have a lot of experience with more professional-level software. It could be a trick of Chroma key with shadows, but I don't know how I would go about doing that on purpose.
