I wrote:It's a portion of the same video only blurred. So normally you'd copy-paste the video, mask it so only a portion of the side is shown, and blur it. do the same on the other side and you're done. You just have to make sure that you're doing it on 16:9.
^ That's exactly what I did. Just had the clip done in 16:9 aspect ratio (and since my monitor is still the good ol' 4:3 with no resolution support except between 800x600 - 1024x768, I had to improvise WWE-style). The only difference is that I was lazy to duplicate the clip again, blur it slightly lesser than that of the sides and mask it (therefore making it the same as they clip you posted).
This may also do the trick on other video-editing software:
So basically the recorded clips are in 4:3, I made a composition in After Effects in 16:9; then I imported all the stuff needed. The recorded clips are then duplicated. The duplicated clip is then stretched to fill out the space in 16:9 then blurred. I then placed the stretched and blurred duplicated clip under the original clip and there you have it.
Side note: rendering your video in WMV format makes the file size so much smaller.
