Here is a youtube link i don't know what dlive is doing while encoding my videos but it didn't work :
Parallax is the effect of different layers of elements of the background moving in independance of each other with some factor of depth of field to take into consideration and the likes, i was just rendering a test to have a preview for myself. (animated some jumps at the beginning to have an idea of how it moves when the character goes higher and there is kinks to work around that.)
My video is at DLive
