I’m new to AF so please bear with me. I made a simple one line text layer over an 8 second mpeg video clip. I applied a preset called Rattle (Presets / Text / Miscellaneous / Rattle). The animation works fine but it only animates for about 2 seconds. How can I make it animate longer? I know how to get to the Layers properties in the Timeline panel but do know which property to change the duration of the animation. I see how to change the Skew but that changed the animation movement itself and not the duration of the animation.
In general, you make an animation longer by moving the keyframes further apart in time.
Please, if you're new to After Effects, work your way through the getting-started materials:
