[ANSWERED] Help needed for a Shader

[jfg]

I have managed to add a horizontal and vertical movement to the shader "circle open", but I can't manage to get the width and height of the oval changeable to get a circle as well. Would be very grateful if someone could help me. 

The original shader:

circle-open.frag.zip

my changed version:

cercle.zip

thanks a lot

So your Texture 1 should be sized to the same XY ratio as the GLSL Shader Width and Height parameters.

You will see if you connect an Shapes with 400x400 resolution to Video 1 - In and set the Width / Height to 400x400 that you will get an circle.

yes, it is clear but if I work with two HD movie as input I get only an ovale and cannot change the proportion.
