out vec4 outputColor;
in vec2 UV;

uniform sampler2D bckbuffer;
uniform vec2 resolution;

uniform float timer;
uniform float loop_timer;

void main() {
    vec2 uv = UV;
    vec2 rs = resolution;

    outputColor = vec4(uv, 1., 1.);
}
'''

scene = FBO(
    ctx = CTX, size = (1080, 1080), shader = shader
)

clip = ClipRenderer(duration=2, fps=30, rest_time=0.)
clip.addFBOPass("", scene)
