Ok so I have a bunch of comps that are on my Editor timeline, they all play fine and is good, I want to a Letterbox to the film so I create a new Video Layer, call it GRADE and put the letterbox effect. Only trouble is it is doing some odd things. In order to see the effect at all I have to have the blend set to NORMAL anything else and its gone. Next the effect only works on part of the project (yes its a full length effect covering all below layers). The same comp on another layer goes black to start with then kicks in. Its all very odd, am I doing something very wrong.
