Is there a way to setup AE so it always interprets the alpha of dpx rendered frames as straight ?
Hello people !
Im working on 3D intensive projects for TV, and all the renders I get from 3Dsmax (Vray) are in DPX and my project workspace is linearized.
Those DPX are rendered non-premultiplied so that I can avoid having edges when I recompose my beauty out of the dozen of Vray elements.Problem is, each time I update the passes with newer renders, the alpha interpretation goes back to premult !! Im wasting hours just to reset the interpretation to straight 🙁
Does someone know if there is a way to force AE to interpret the alpha of any given footage to straight ??
Thanks folks
E.

In this thread, near the bottom Walter Soyka discusses how to change AE’s interpretation by editing the interpretation doc:

Thank you very much John
I found the line that was causing me such a trouble :
# OpenEXR is premultiplied by convention
*, *, *, "oEXR", * ~ *, *, *, P, *, *I changed it to
# OpenEXR is straight by convention
*, *, *, "oEXR", * ~ *, *, *, S, *, *
