Best and easiest way to delete a layer by a specific time in the After Effects timeline I use Adobe After Effects (Last version) for video editing
I created a composition with a video, shape and null Object. So far everything work well.
Now I want to hide the layer from a certain point in my timeline.
Let say my timeline is 10s, I want my layer to be visible at the first 3s and then to be invisible the remaining seconds

What is the best and easiest way to perform that?
Thank You
Make a key frame (or more than one at different points) on the Opacity control. You can get to it by selecting the layer and pressing T. Or open up all the triangles to find it. Set the opacity to zero to make the layer invisible.
