I am familiar with composition settings and duration. What I am not quite clear on is how to change or lengthen the animation within the composition while retaining the original format it was designed for. If I change the duration of the composition to the length of my 7:00 video but do not change the intended video holders accordingly, I would have 2 minutes of animated elements and then just see the rest of my video without any effects. Rest assured I do not just start asking questions on forums without prior research and a solid attempt at resolving my own issues. If this forum, which I thought was for beginners, is not an appropriate place for my request of information, I will just seek help elsewhere. Thanks for your time and detailed response!
