I am trying to do a school video about India. I have a block of text as different layers inside a pre-comp. the is pre-comp is on top of a Photo-shop background and a video of clouds. I hit auto trace for the pre-comp and then applied the stroke effect to all the mask in the pre-comp. I then key framed it out to appear as if the text wrote on. however when I render after the text writes on some of the letters start to flash on and off. I don't really know what is happening that is causing this any help?
PC: windows 7 Professional 64 bit, i7 quad @ 2.67GHZ, 12 gigs of ram, quadro 4000.
After effects CS5.
all i changed in the stroke effect is:
all mask, stroke sequentially, brush size: 4.5, Reveal composition.
also the text I am applying to is scrolling up across the screen.
