One is a render from lightwave of a tornado that I have added colour correction to and extra particle effects in ae.
The second is footage of actors that is blue screen with keylight plugin on all of them and extra bits and bats as if they are in a tornado.
I finish all the work friday night and render out a test.
I then decided the next day to do some more. I try to render it out after the tweaks (mainly just timing and adding a few glows around the actors) and it freezes mid render. No message, just hangs forever.
I take the fx of that part and render a test. Its fine. So i delete all the fx of that one clip and make new ones. The test renders fine.
So I stick it on a full render. It hangs somewhere else.
I try the lightwave footage and that hangs at the end of the render no matter what I do.
I have resigned myself to doing the whole thing again, but are there any suggestions to what might have caused this so i dont fall into the trap again?
