DH_FieldTrans is a transition effect which provides an easy solution to the problem of applying effects to clips which have vision cuts on field two.
Cutting it Fine
DH_FieldTrans is the simplest plug-in we've ever created. As you can see, it has no controls at all.
Just apply it as a transition effect and set the duration to one frame. The cut between the clips will happen on field two rather than field one, so you can now apply different effects to each clip without any fear of flash fields appearing.
