Downloading a photobucket remix to the computer, is it possible?

[J=n=o]

Hey

First of all, sorry if it is in the wrong section although I think it isn't. I made a remix in photobucket with the thing they have from Adobe. So first of all I notice it has a different extension: .pbr. I don't know if it is possible to download the video. Like all the possible ways that you can with youtube videos or others. I was wondering if someone knows how or has done it.

Thanks in advance.
