Searched on the forum but i haven't find a good way to change a jit.videoplane to the same proportions then the texture on that jit.videoplane.
a texture is 4:3 then videoplane is 4:3
new texture is 16:9 then videoplane changes to 16:9
new texture is 12:4 then videoplane changes to 12:4
and so on ...
Now textures are stretched or compressed on jit.videoplanes.
