Thanks for response Kalleheikki.
But footages are pre composed more than once and there are lots of motion graphic elements inside of those compositions. I want to grade them without affecting those motion graphics. Also there are different shots, i did different grade for each of them.
what i am trying to archive is applying an effect direcly to source file but apperanly there is no much a thing in ae.
It’s weird that nobody asked this before.
