Looking for a painting on video tutorial

I'm a new media artist and recently purchsed Corel being excited at the possibility of painting on video, however information seems to be scant and wondering if someone can point me to tutorials.Working with video in Corel is very different to working with Premiere or After Effects, the timeline is reduced to single frames. As video is 25 or 30 fps, I was expecting some kind of tweening or keyframe option?
