Thanks for the reply Seth. I just compressed some test images to OpenEXR B44 4:2:0 using rvio (which is fantastic btw), and when trying to read these images into Nuke, I get the same error as with images compressed using ProEXR from After Effects CS5.5. I have tried reading 4:2:0 yryby EXR in

Try a shuffle node after the Read and grab just rgba. I'm not at my machine, but from memory even the flattened result that you're after needs to be shuffled out to rgba. Not sure what the image is that comes directly out of a Read psd is doing. -Dan On Mar 2, 2012, at 5:40 AM, lozo
