Piku Piku is a fun video selfie app with awesome filters! I've been playing around with it few days and it's really fun! (and I play with a lot of GIF apps lol)
The end result is you get a really cool GIF or Video, I like that it auto saves to your phone which makes it really easy to try out a bunch of different things, and the filters... are awesome! I actually paid to get all of them :) and the the experience was really smooth. Like really smooth.
Here is me flipping through all the filters:
