Intro to Masking with After Effects

Get your workspace ready


Add the text and position it or add the animation you want


I am adding some drop shadow to this text


going to position it on the far right so it scrolls across the page


mark the keyframe on position


scroll through the video, move the text to it’s next location


the mask


Add a solid layer, color doesnt matter


looks like this


move this layer to the bottom, but keep it selected


I like to use the ruler to know the area of the text


ctrl r brings up the ruler, you can click and drag from the ruler to create these lines


move it to the bottom


move to the portion of the video where the text crosses path with the object


pen tool


use the pen tool and select around the object


move your mask above the text layer


select alpha inverted


expand out the mask and transform


mark the keyframes for mask path, position and scale


move through the footage, keeping the object covered with the mask


bounce around through the video moving the mask as you go


this turned out poorly, but you get the idea
