Hello vade,
I am able to reproduce it.
it seems that the colour corrected movie has different coordinates in
the CI space (don't know what the correct name is. working space
perhaps)
I tested it with image 1 larger than image 2. When I do that and
enable colour correction then I have to shift the image vertically by
the dimensions difference.
say image 1 is 1024 x 768
image 2 is 640 x 480
then I have to shift image 2 up by (768-480)px = 288px
vec4 img2 = sample(image2, (samplerCoord(image2) + vec2(0,288) )/
maxSize * samplerSize(image2) );
A long time ago when I read the CI manual I think that I can remember
a part where the image is usualy positioned into the first quadrant in
CI space. When correcting the colours it seems to no longer apply.
Don't know whether it is intended to be so but in my opinion it is not
because I can't see any sense behind that.
At least this little hint will give you a workaround.
-Michael
