Hey everybody,
Hoping someone can enlighten me. I'm working on a project that's a music video. I may be doing it all wrong I'm just winging it and learning as I go. Anyway there's a ton of characters and props. It's basically one long video that uses the visible function a lot. I've added characters at about frame 875. Seem like when I add a character at this point it creates key frames at frame zero. So I've been making the character or props invisible at frame zero and then visible at the frame it needs to show up. Well when I rendered exporting to After Affects there's 874 black images in the sequence portion before the image appears. Is there a way to set things up where the character or props just start at the frame they're created at instead of creating key frames back to zero. I could be wrong but it seems like it add a bunch of extra stuff to render and uses unnecessary memory.  Hope you have some ideas. 
Thanks 
Larry
