I am working on a project in PPro CS 6 and everytime I put down a crossfade I have to render it. Why?
In fact when I put down any kind of effect on a clip or transition between clips, it has to render.
Do all transitions and effects have to rendered?
Is there a seting where I can change this?
Thanks in advance
Depends on hardware, sequence settings and source material. You did not tell that, so there is nobody who can tell whether that is normal.
You don't necessarily have to render just because it's red. Only do so if it doesn't play back smooth and you need it to.
A good way to tell if its playing smoothly (not dropping frames) is to activate the Dropped Frame Indcator in the Program Window.
