> Well, if you don’t need the arrow head just use Media Generator to create a solid color rectangle and give it the dimensions of your line (e.g., 400 x 5). Then use pan crop to animate the two positions.
…and if you do need an arrow head, add the Sony Cookie Cutter FX to the generated media and select the arrow head shape and animate it as well.
– OR –
Drop a solid generated media and use the mask tool to draw and animate any size or shaped arrow that you want. Animating the masks can be done with just two keyframes.
