I want to put a moving image in the background, a small 8MB MP4 video with 23 seconds of animation. I choose the video as the background but it just opens, it is not at the bottom of the RETROARCH menu. can someone help me how do i do this? should I convert this MP4 file to another file? please help me 
RetroArch doesn’t support video backgrounds, sorry. The animated backgrounds we have for XMB are specially crafted pixel shaders.
ohhhhhhhhhhhhhh no
