Interrupting Render On-the-Fly
Using Render On-the-Fly can slow down your editing of a sequence. If you are compositing and then change the frame you are monitoring, you must wait for the single frame to render.
Instead of waiting for rendering to finish, you can interrupt Render On-the-Fly. Interrupting Render On-the-Fly interrupts only the rendering of non-real-time effects.
To interrupt Render On-the-Fly, do one of the following:
  Drag the position indicator in the Timeline.
While you are dragging, the sequence appears in the Composer monitor as it would if Render On-the-Fly were not selected from the Clip menu.
  If you click in the Timeline and rendering begins, quickly move to another location in the Timeline. This interrupts the rendering process until you release the mouse button.
