How do you mix (pix-mix) images and film in GEM? I get this error message when I try, [pix_mix]: two images do not have equal dimensions (320x240 != 2100x1400). Do i have to custom shape the image dimensions to match the film images?

yes you can do that. or than use alpha blending in two renderchains to blend the between the two sources

Thanks Johnny. I am pretty new to this. How would you use alpha blending?

I have also been messing around with pix_resize, matching the dimensions of the lower dimension (the film), and it is almost working...

sorry for the late reply. I have this problem about the alpha blending i tried to fix before answer you, but i couldn't. but as long as you blend only the video in the front it doesn't matter. You will understand when opening the patch.blending.pd
