Make a comp-sized solid. Put it on the layer over the hole. Reduce its opacity temporarily to about 50%. Using the pen tool, make a hole-shaped mask. Put the solid's opacity back up to 100%. Make the credit roll, on top of the hole and below the masked solid. Use the solid as a track matte.
Hey Dave, thanks for answering!
However, I think I've run into a little problem.
I made a video of the rolling credits (an mp4 file that lasts about 20 seconds) and when I bring it into the project, it comes up like this. the borders of the video don't disappear the layer of the mask.
Is there a way that I can have the video file peek through the hole? Like, I want the words to roll upwards, but the video would be inside the hole itself, and you cannot see the edges of the video file. I'm a bit confused.
This is the hole here (without obtrusive the video file):
Thanks so much!
Hi Dave! Just saying that I managed to get it done in the end! Thanks a bunch!
