Hi Everyone,

If someone can share their AE wisdom that would be much appreciated.

I am trying to add a trim path to a shape layer (circle) and then animate the 'Start' option so the circle starts with 100% solid color fill then finishes with 0% (which reveals a video underneath),

The issue I cannot figure out is that I want the trim path to reduce the fill clockwise e.g. as if a big hand of the clock was removing the fill in a clockwise motion. At the moment, it looks like it is following the stroke path to remove the fill of the circle.

Is there a setting that I am missing or am I using the right method?

Trim path modifies the path itself, sweeping one endpoint along the path and leaving the ends open. This is easier to see if you apply a stroke to the shape layer.

When you fill the path, Ae squares off the open endpoints, connecting them directly with an imaginary boundary for the fill.

To do a clock wipe, you can either use the Radial Wipe effect on the shape layer, or you can keep trim path but turn off the fill and use a stroke whose width is set to the size of the ellipse path.

Cheers Walter! Radial Wipe has done the job.
