@-chamkilli-:Use a black background and make sure ur black background is much bigger than ur gif.
Then group ur gif layer,make sure u add a Black and white gradient to it and add a layer mask.
Now choose ur eraser tool,SOFT BRUSH,lower ur opacity and fill erase the gif.That seems to be most of it..though there could be a little more to it..i will a tut in tumblr
