Good lime-warm-day! 
search for help…
I have a huge openEXR file (35K for example) with a large number of passes(777 for example :). Whether there is any software to create a smaller proxy file from the original one? And the number of passes, their names and all the rest must be the same, but the resolution of the file.
thx!
